When software has been supported and maintained for almost ten years, like World of Warcraft, it is not clear whether the worst compatible machine at launch should remain supported or whether the requirements should increase over time. For instance, when Windows XP launched, the OS was tuned for 128MB of RAM. Later updates made it be highly uncomfortable with anything less than a whole gigabyte. For games though, we mostly pretend that they represent the time that they were released.
That mental model does not apply to World of Warcraft: Warlords of Draenor. While technically this is an expansion pack, its requirements jumped again (significantly if compared to the original release). Even the first expansion pack, Burning Crusade, was able to run on a GeForce 2. Those cards were bundled with the original Unreal Tournament, which was a relatively new game at the time that the GeForce 2 was released.
Now? Well the minimum is:
- Windows XP or later.
- Intel Core 2 Duo E6600 or AMD Phenom X3 8750
- NVIDIA GeForce 8800 GT, AMD Radeon HD 4850), or Intel HD Graphics 3000.
- 2GB of RAM
- 35GB HDD
And the recommended is:
- Windows 7 or 8 (x86-64)
- Intel Core i5 2400 or AMD FX-4100
- NVIDIA GeForce GTX 470 or AMD Radeon HD 5870
- 4GB of RAM
- 35GB HDD
World of Warcraft, and other MMORPGs, might get a pass on this issue. With its subscription model, there is not really an expectation that a user can go back and see the game in the same state as it launched. It is not a work, but a service -- and that does not devalue its artistic merits. It just is not really the same game now that it was then.
World of Warcraft: Warlords of Draenor will launch on November 13th.

DDR4 is starting to arrive at NewEgg and some kits are actually in stock for those who want to be the first on their block to have these new DIMMs and can remortgage their home. The price of Haswell-E CPUs and motherboards is as of yet unknown but looking over the past few years of Intel's new processors you can assume the flagship processor will be around $999.99 with the feature rich motherboards starting around $200 and quickly raising from there.
At the 16GB mark you have more choices with Corsair joining in and a range of speeds that go up to DDR4-2800 as well as your choice of a pair of 8GB DIMMs or four 4GB DIMMs. Corsair was kind enough to list the timings, the DDR4-2666 @ 15-17-17-35 and the DDR4-2800 @ 16-18-18-36 though you will certainly pay a price for the RAM with the highest frequencies.
For those on a budget it would seem like waiting is your best choice, especially as Amazon is offering a limited selection of the new kits, as there is only a single 8GB kit from Crucial although you can buy two of the single DIMMs without heatspreaders for $110.
Intel product releases are always dearly priced, the introduction of a new generation of RAM is both exciting and daunting. You will see power reductions, base frequencies that were uncommon in DDR3 and very likely an increase in the ability to overclock these DIMMs but it is going to cost you. If Haswell-E is in your sights you should start planning on how to afford replacing your CPU, motherboard and RAM at the same time as this is no refresh this is a whole new product line.

Tagged: battlefield, medal of honor, ea
Last year, we got Battlefield 4. The year before? Medal of Honor: Warfighter. The year before? Battlefield 3. The year before? Medal of Honor (Reboot). We will not be getting a new Medal of Honor this year, because Danger Close was shut down in June 2013. Danger Close developed the two recent Medal of Honor titles and, as EA Los Angeles, many of the previous Medal of Honor titles and many RTS games (Command and Conquer, Red Alert, Lord of the Rings: The Battle for Middle-Earth).
Many of their employees are now working at DICE LA.
So, when a new Medal of Honor title should be released, we get Battlefield: Hardline. A person with decent pattern recognition might believe that Battlefield, or its spinoffs, would fill the gap left by Medal of Honor. Not so, according to Patrick Söderlund, Executive VP of EA Studios. As was the case at E3, where both studios (DICE and Visceral) repetitively claimed that Battlefield: Hardline was the product (literally) of a fluke encounter and pent-up excitement for cops and robbers.
Of course, they do not close the door for annualized Battlefield releases, either. They just say that it is not their plan to have that be "the way it's going to be forever and ever". Honestly, for all the hatred that annualized releases get, the problem is not the frequency. If EA can bring out a Battlefield title every year, and one that is continually a good game, then power to them. The problem is that, with an annual release cycle, it is hard to get success-after-success, especially when fatigue is an opposing, and (more importantly) ever-increasing force.
It is the hard, but lucrative road.

Tagged: sandisk, fusion-io, buyout
Fusion-io was once a behemoth of flash memory storage. Back when SSDs were having a hard time saturating SATA 3Gb/sec, Fusion-io was making fire breathing PCIe SSDs full of SLC flash and pushing relatively insane IOPS and throughput figures. Their innovations were a good formula at the time. They made the controller a very simple device, basically just a simple bridge from the PCIe bus to the flash memory. This meant that most of the actual work was done in the driver. This meant that Fusion-io SSDs were able to leverage the CPU and memory of the host system to achieve very high performance.
Fusion-io ioDrive 160 creams the competition back in 2010.
Being the king of IOPS back in the early days of flash memory storage, Fusion-io was able to charge a premium for their products. In a 2010 review, I priced their 160GB SSD at about $40/GB. In the years since, while flash memory prices (and therefore SSD products) have steadily dropped in price while achieving higher and higher performance figures, Fusion-io products have mostly remained static in price. All of this time, the various iterations of the ioDrive continued to bank on the original model of a simple controller and the bulk of the work taking place in the driver. This actually carries a few distinct disadvantages, in that the host system has to spent a relatively large amount of CPU and memory resources towards handling the Fusion-io devices. While this enables higher performance, it leaves less resources available to actually do stuff with the data. This ends up adding to the build cost of a system, as more CPU cores and memory must be thrown at the chassis handling the storage. In more demanding cases, additional systems would need to be added to the rack space in order to handle the additional storage overhead in addition to the other required workloads. Lastly, the hefty driver means Fusion-io devices are not bootable, despite early promises to the contrary. This isn't necessarily a deal breaker for enterprise use, but it does require system builders to add an additional storage device (from a different vendor) to handle OS duties.
In 2014, the other guys are making faster stuff. Note this chart is 4x the scale of the 2010 chart.
Lets fast forward to present times. Just over a week ago, Fusion-io announced their new 'Atomic' line of SSDs. The announcement seemed to fall flat, and did little to save the continuous decline of their stock price. I suspect this was because despite new leadership, these new products are just another iteration of the same resource consuming formula. Another reason for the luke warm reception might have been the fact that Intel launched their P3700 series a few days prior. The P3700 is a native PCIe SSD that employs the new NVM Express communication standard. This open standard was developed specifically for flash memory communication, and it allows more direct access to flash in a manner that significantly reduces the overhead required to perform high data throughputs and very high IO's per second. NVMe is a very small driver stack with native support built into modern operating systems, and is basically the polar opposite of the model Fusion-io has relied on for years now.
Intel's use of NVMe enables very efficient access to flash memory with minimal CPU overhead.
Fusion-io's announcement claimed "The Atomic Series of ioMemory delivers the highest transaction rate per gigabyte for everything from read intensive workflows to mixed workloads.". Let's see how this stacks up against the Intel P3700 - an SSD that launched the same week:
|Model||Fusion-io PX600||Intel P3700|
|Interface / Flash type||PCIe 2.0 x8 / 20nm MLC||PCIe 3.0 x4 / 20nm MLC|
|Read BW (GB/sec)||2.7||2.7||2.7||2.7||2.7||2.8||2.8||2.8|
|Write BW (GB/sec)||1.5||1.7||2.2||2.1||1.2||1.9||1.9||1.9|
|4k random read IOPS||196,000||235,000||330,000||276,000||450,000||460,000||450,000||450,000|
|4k random write IOPS||320,000||370,000||375,000||375,000||75,000||90,000||150,000||175,000|
|4k 70/30 R/W IOPS||Unlisted||150,000||200,000||240,000||250,000|
|Endurance / TB||12.0||12.3||12.3||12.3||18.3||18.3||18.3||18.3|
|Warranty||5 years||5 years|
We are comparing flagship to flagship (in a given form factor) here. Starting from the top, the Intel P3700 is available in generally smaller capacities than the Fusion-io PX600. Both use 20nm flash, but the P3700 uses half the data lanes at twice the throughput. Regarding Fusion-io's 'transaction rate per GB' point, well, it's mostly debunked by the Intel P3700, which has excellent random read performance all the way down to its smallest 400GB capacity point. The seemingly unreal write specs seen from the PX600 are, well, actually unreal. Flash memory writes take longer than reads, so the only logical explanation for the inversion we see here is that Fusion-io's driver is passing those random writes through RAM first. Writing to RAM might be quicker, but you can't sustain it indefinitely, and it consumes more host system resources in the process. Moving further down the chart, we see Intel coming in with a ~50% higher endurance rating when compared to the Fusion-io. The warranties may be of equal duration, but the Intel drive is (on paper / stated warranty) guaranteed to outlast the Fusion-io part when used in a heavy write environment.
For pricing, Intel launched the P3700 at a competitive $3/GB. Pricing data for Fusion-io is not available, as they are behind a bit of a 'quote wall', and no pricing at all was included with the Atomic product launch press materials. Let's take a conservative guess and assume the new line is half the cost/GB of their previous long-standing flagship, the Octal. One vendor lists pricing directly at $124,995 for 10.24TB ($12.21/GB) and $99,995 for 5.12TB ($19.53/GB), both of which require minumum support contracts as an additional cost. Half of $12/GB is still more than twice the $3/GB figure from Intel.
My theory as to why SanDisk is going for Fusion-io?
- A poor track record since the Fusion-io IPO have driven the stock price way down, making it prime for a buyout.
- SanDisk is one of the few remaining flash memory companies that does not own their own high end controller tech.
- Recent Fusion-io product launch overshadowed by much larger (Intel) company launching a competing superior product at a lower cost/GB.
So yeah, the buyout seemed inevitable. The question that remains is what will SanDisk do with them once they've bought them? Merging the two will mean that Fusion-io can include 'in house' flash and (hopefully) offer their products at a lower cost/GB, but that can only succeed if the SanDisk flash performs adequately. Assuming it does, there's still the issue of relatively high costs when compared to freshly competing products from Intel and others. Last but not least is the ioDrive driver model, which grows incresingly dated while the rest of the industry adopts NVMe.

Tagged: x86, restructure, gpu, arm, APU, amd
According to VR-Zone, AMD has reworked their business, last Thursday, sorting each of their projects into two divisions and moving some executives around. The company is now segmented into the "Enterprise, Embedded, and Semi-Custom Business Group", and the "Computing and Graphics Business Group". The company used to be divided between "Computing Solutions", which handled CPUs, APUs, chipsets, and so forth, "Graphics and Visual Solutions", which is best known for GPUs but also contains console royalties, and "All Other", which was... everything else.
Lisa Su, former general manger of global business, has moved up to Chief Operating Officer (COO), along with other changes.
This restructure makes sense for a couple of reasons. First, it pairs some unprofitable ventures with other, highly profitable ones. AMD's graphics division has been steadily adding profitability to the company while its CPU division has been mostly losing money. Secondly, "All Other" is about a nebulous as a name can get. Instead of having three unbalanced divisions, one of which makes no sense to someone glancing at AMD's quarterly earnings reports, they should now have two, roughly equal segments.
At the very least, it should look better to an uninformed investor. Someone who does not know the company might look at the sheet and assume that, if AMD divested from everything except graphics, that the company would be profitable. If, you know, they did not know that console contracts came into their graphics division because their compute division had x86 APUs, and so forth. This setup is now more aligned to customers, not products.

It should not pass anyone's smell test but it apparently does, according to tweets and other articles. Officially, the TrueCrypt website (which redirects to their SourceForge page) claims that, with the end of Windows XP support (??), the TrueCrypt development team wants users to stop using their software. Instead, they suggest a switch to BitLocker, Mac OSX built-in encryption, or whatever random encryption suite comes up when you search your Linux distro's package manager (!?). Not only that, but several versions of Windows (such as 7 Home Premium) do not have access to BitLocker. Lastly, none of these are a good solution for users who want a single encrypted container across multiple OSes.
A new version (don't use it!!!) called TrueCrypt 7.2 was released and signed with their private encryption key.
The developers have not denied the end of support, and its full-of-crap reason. (Seriously, because Microsoft deprecated Windows XP almost two months ago, they pull support for a two year old version now?)
They have also not confirmed it. They have been missing since at least "the announcement" (or earlier if they were not the ones who made it). Going missing and unreachable, the day of your supposedly gigantic resignation announcement, does not support the validity of that announcement.
To me, that is about as unconfirmed as you can get.
Still, people are believing the claims that TrueCrypt 7.1a is not secure. The version has been around since February 2012 and, beyond people looking at its source code, has passed a significant portion of a third-party audit. Even if you believe the website, it only says that TrueCrypt will not be updated for security. It does not say that TrueCrypt 7.1a is vulnerable to any known attack.
In other words, the version that has been good enough for over two years, and several known cases of government agencies being unable to penetrate it, is probably as secure today as it was last week.
"The final version", TrueCrypt 7.2, is a decrypt-only solution. It allows users to unencrypt existing vaults, although who knows what else it does, to move it to another solution. The source code changes have been published, and they do not seem shady so far, but since we cannot even verify that their private key has not leaked, I wouldn't trust it. A very deep compromise could make finding vulnerabilities very difficult.
So what is going on? Who knows. One possibility is that they were targeted for a very coordinated hack, one which completely owned them and their private key, performed by someone(s) who spent a significant amount of time modifying a fake 7.2 version. Another possibility is that they were legally gagged and forced to shut down operations, but they managed to negotiate a method for users to decrypt existing data with a neutered build.
One thing is for sure, if this is a GoG-style publicity stunt, I will flip a couple of tables.
We'll see. ┻━┻ \_(ツ)_/ ┻━┻

Tagged: ultraviolet, mozilla, DRM, Adobe Access, Adobe
Needless to say, DRM is a controversial topic and I am clearly against it. I do not blame Mozilla. The non-profit organization responsible for Firefox knew that they could not oppose Chrome, IE, and Safari while being a consumer software provider. I do not even blame Apple, Google, and Microsoft for their decisions, either. This problem is much bigger and it comes down to a total misunderstanding of basic mathematics (albeit at a ridiculously abstract and applied level).
Simply put, piracy figures are meaningless. They are a measure of how many people use content without paying (assuming they are even accurate). You know what is more useful? Sales figures. Piracy figures are measurements, dependent variables, and so is revenue. Measurements cannot influence other measurements. Specifically, measurements cannot influence anything because they are, themselves, the result of influences. That is what "a measure" is.
Implementing DRM is not a measurement, however. It is a controllable action whose influence can be recorded. If you implement DRM and your sales go down, it hurt you. You may notice piracy figures decline. However, you should be too busy to care because you should be spending your time trying to undo the damage you did to your sales! Why are you looking at piracy figures when you're bleeding money?
I have yet to see a DRM implementation that correlated with an increase in sales. I have, however, seen some which correlate to a massive decrease.
The thing is, Netflix might know that and I am pretty sure that some of the web browser companies know that. They do not necessarily want to implement DRM. What they want is content and, surprise, the people who are in charge of the content are definitely not enlightened to that logic. I am not even sure if they realize that the reason why content is pirated before their release dates is because they are not leaked by end users.
But whatever. Technical companies, who want that content available on their products, are stuck finding a way to appease those content companies in a way that damages their users and shrinks their potential market the least. For Mozilla, this means keeping as much open as possible.
Since they do not have existing relationships with Hollywood, Adobe Access will be the actual method of displaying the video. They are clear to note that this only applies to video. They believe their existing relationships in text, images, and games will prevent the disease from spreading. This is basically a plug-in architecture with a sandbox that is open source and as strict as possible.
This sandbox is intended to prevent a security vulnerability from having access to the host system, give a method of controlling the DRM's performance if it hitches, and not allow the DRM to query the machine for authentication. The last part is something they wanted to highlight, because it shows their effort to protect the privacy of their users. They also imply a method for users to opt-out but did not go into specifics.
As an aside, Adobe will support their Access DRM software on Windows, Mac, and Linux. Mozilla is pushing hard for Android and Firefox OS, too. According to Adobe, Access DRM is certified for use with Ultraviolet content.
I accept Mozilla's decision to join everyone else but I am sad that it came to this. I can think of only two reasons for including DRM: for legal (felony) "protection" under the DMCA or to make content companies feel better while they slowly sink their own ships chasing after numbers which have nothing to do with profits or revenue.
Ultimately, though, they made a compromise. That is always how we stumble and fall down slippery slopes. I am disappointed but I cannot suggest a better option.

Tagged: mozilla, net neutrality
Recently, the FCC has been moving to give up Net Neutrality. Mozilla, being dedicated to the free (as in speech) and open internet, has offered a simple compromise. Their proposal is that the FCC classifies internet service providers (ISPs) as common carriers on the server side, forcing restrictions on them to prevent discrimination of traffic to customers, while allowing them to be "information services" to consumers.
In other words, force ISPs to allow services to have unrestricted access to consumers, without flipping unnecessary tables with content distribution (TV, etc.) services. Like all possibilities so far, it could have some consequences, however.
"Net Neutrality" is a hot issue lately. Simply put, the internet gives society an affordable method of sharing information. How much is "just information" is catching numerous industries off guard, including ones which Internet Service Providers (ISPs) participate in (such as TV and Movie distribution), and that leads to serious tensions.
On the one hand, these companies want to protect their existing business models. They want consumers to continue to select their cable and satellite TV packages, on-demand videos, and other services at controlled profit margins and without the stress and uncertainty of competing.
On the other hand, if the world changes, they want to be the winner in that new reality. Yikes.
A... bad... photograph of Mozilla's "UP" anti-datamining proposal.
Mozilla's proposal is very typical of them. They tend to propose compromises which divides an issue such that both sides get the majority of their needs. Another good example is "UP", or User Personalization, which tries to cut down on data mining by giving a method for the browser to tell websites what they actually want to know (and let the user tell the browser how much to tell them). The user would compromise, giving the amount of information they find acceptable, so the website would compromise and take only what they need (rather than developing methods to grab anything and everything they can). It feels like a similar thing is happening here. This proposal gives users what they want, freedom to choose services without restriction, without tossing ISPs into "Title II" common carrier altogether.
Of course, this probably comes with a few caveats...
The first issue that pops in my mind is, "What is a service?". I see this causing problems for peer-to-peer applications (including BitTorrent Sync and Crashplan, excluding Crashplan Central). Neither endpoint would necessarily be classified as "a server", or at least convince a non-technical lawmaker that is the case, and thus ISPs would not need to apply common carrier restrictions to them. This could be a serious issue for WebRTC. Even worse, companies like Google and Netflix would have no incentive to help fight those battles -- they're legally protected. It would have to be defined, very clearly, what makes "a server".
Every method will get messy for someone. Still, the discussion is being made.

Tagged: TDP, Athlon 5350, Asus AM1I-A, amd, AM1
If I had one regret about my AM1 review that posted a few weeks ago, it was that I used a pretty hefty (relatively speaking) 500 watt power supply for a part that is listed at a 25 watt TDP. Power supplies really do not hit their efficiency numbers until they are at least under 50% load. Even the most efficient 500 watt power supply is going to inflate the consumption numbers of these diminutive parts that we are currently testing.
Keep it simple... keep it efficient.
Ryan had sent along a 60 watt notebook power supply with an ATX cable adapter at around the same time as I started testing on the AMD Athlon 5350 and Asus AM1I-A. I was somewhat roped into running that previously mentioned 500 watt power supply due to comparative reasons. I was using a 100 watt TDP A10-6790 APU with a pretty loaded Gigabyte A88X based ITX motherboard. That combination would have likely fried the 60 watt (12v x 5A) notebook power supply under load.
Now that I had a little extra time on my hands, I was able to finally get around to seeing exactly how efficient this little number could get. I swapped the old WD Green 1 TB drive for a new Samsung 840 EVO 500 GB SSD. I removed the BD-ROM drive completely from the equation as well. Neither of those parts uses a lot of wattage, but I am pushing this combination to go as low as I possibly can.
The results are pretty interesting. At idle we see the 60 watt supply (sans spinning drive and BD-ROM) hitting 12 watts as measured from the wall. The 500 watt power supply and those extra pieces added another 11 watts of draw. At load we see a somewhat similar numbers, but not nearly as dramatic as at idle. The 60 watt system is drawing 29 watts while the 500 watt system is at 37 watts.
So how do you get from a 60 watt notebook power adapter to ATX standard? This is the brains behind the operation.
The numbers for both power supplies are both good, but we do see that we get a nice jump in efficiency from using the smaller unit and a SSD instead of a spinning drive. Either way, the Athlon 5350 and AMD AM1 infrastructure sip power as compared to most desktop processors.

Valve does not release sales or hours played figures for any game on Steam and it is rare to find a publisher who will volunteer that information. That said, Steam user profiles list that information on a per-account basis. If someone, say Ars Technica, had access to sufficient server capacity, say an Amazon Web Services instance, and a reasonable understanding of statistics, then they could estimate.
If interested, I would definitely look through the original editorial for all of its many findings. Here, if you let me (and you can't stop me even if you don't), I would like to add my own analysis on a specific topic. The Elder Scrolls V: Skyrim on the PC, according to VGChartz, sold 3.42 million copies on at retail, worldwide. The thing is, Steamworks was required for every copy sold at retail or online. According to Ars Technica's estimates, 5.94 million copies were registered with Steam.
5.94 minus 3.42 is 2.52 million copies sold digitally. Almost a third of PC sales were made through Steam and other digital distribution platforms. Also, this means that the PC was the game's second-best selling platform, ahead of the PS3 (5.43m) and behind the Xbox 360 (7.92m), minus any digital sales on those platforms if they exist, of course. Despite its engine being programmed in DirectX 9, it is still a fairly high-end game. That is a fairly healthy install base for decent gaming PCs.

While Mantle and DirectX 12 are designed to reduce overhead and keep GPUs loaded, the conversation shifts when you are limited by shader throughput. Modern graphics processors are dominated by sometimes thousands of compute cores. Video drivers are complex packages of software. One of their many tasks is converting your scripts, known as shaders, into machine code for its hardware. If this machine code is efficient, it could mean drastically higher frame rates, especially at extreme resolutions and intense quality settings.
Emil Persson of Avalanche Studios, probably known best for the Just Cause franchise, published his slides and speech on optimizing shaders. His talk focuses on AMD's GCN architecture, due to its existence in both console and PC, while bringing up older GPUs for examples. Yes, he has many snippets of GPU assembly code.
AMD's GCN architecture is actually quite interesting, especially dissected as it was in the presentation. It is simpler than its ancestors and much more CPU-like, with resources mapped to memory (and caches of said memory) rather than "slots" (although drivers and APIs often pretend those relics still exist) and with how vectors are mostly treated as collections of scalars, and so forth. Tricks which attempt to combine instructions together into vectors, such as using dot products, can just put irrelevant restrictions on the compiler and optimizer... as it breaks down those vector operations into those very same component-by-component ops that you thought you were avoiding.
Basically, and it makes sense coming from GDC, this talk rarely glosses over points. It goes over execution speed of one individual op compared to another, at various precisions, and which to avoid (protip: integer divide). Also, fused multiply-add is awesome.
I know I learned.
As a final note, this returns to the discussions we had prior to the launch of the next generation consoles. Developers are learning how to make their shader code much more efficient on GCN and that could easily translate to leading PC titles. Especially with DirectX 12 and Mantle, which lightens the CPU-based bottlenecks, learning how to do more work per FLOP addresses the other side. Everyone was looking at Mantle as AMD's play for success through harnessing console mindshare (and in terms of Intel vs AMD, it might help). But honestly, I believe that it will be trends like this presentation which prove more significant... even if behind-the-scenes. Of course developers were always having these discussions, but now console developers will probably be talking about only one architecture - that is a lot of people talking about very few things.
This is not really reducing overhead; this is teaching people how to do more work with less, especially in situations (high resolutions with complex shaders) where the GPU is most relevant.

If you use the Firefox browser on a PC, you are probably using its "Desktop" application. They also had a version for "Modern" Windows 8.x that could be used from the Start Screen. You probably did not use it because fewer than 1000 people per day did. This is more than four orders of magnitude smaller than the number of users for Desktop's pre-release builds.
Yup, less than one-thousandth.
Jonathan Nightingale, VP of Firefox, stated that Mozilla would not be willing to release the product without committing to its future development and support. There was not enough interest to take on that burden and it was not forecast to have a big uptake in adoption, either.
From what we can see, it's pretty flat.
Paul Thurrott of WinSupersite does not blame Mozilla for killing "Metro" Firefox. He acknowledges that they gave it a shot and did not see enough pre-release interest to warrant a product. He places some of the blame on Microsoft for the limitations it places on browsers (especially on Windows RT). In my opinion, this is just a symptom of the larger problem of Windows post-7. Hopefully, Microsoft can correct these problems and do so in a way that benefits their users (and society as a whole).

Late yesterday night, Valve released source code from their "ToGL" transition layer. This bundle of code sits between "[a] limited subset of Direct3D 9.0c" and OpenGL to translate engines which are designed in the former, into the latter. It was pulled out of the DOTA 2 source tree and published standalone... mostly. Basically, it is completely unsupported and probably will not even build without some other chunks of the Source engine.
Still, Valve did not need to release this code, but they did. How a lot of open-source projects work is that someone dumps a starting blob, and if sufficient, the community pokes and prods it to mold it into a self-sustaining entity. The real question is whether the code that Valve provided is sufficient. As often is the case, time will tell. Either way, this is a good thing that other companies really should embrace: giving out your old code to further the collective. We are just not sure how good.
ToGL is available now at Valve's GitHub page under the permissive, non-copyleft MIT license.

UPDATE (Feb 26th): Our readers pointed out in the comments, although I have yet to test it, that you can change Origin's install-to directory before installing a game to have them on a separate hard drive as the rest. Not as easy as Steam's method, but apparently works for games like this that you want somewhere else. I figured it would forget games in the old directory, but apparently not.
Well, okay. Titanfall will require a significant amount of hard drive space when it is released in two weeks. Receiving the game digitally will push 21GB of content through your modem and unpack to 48GB. Apparently, the next generation has arrived.
Honestly, I am not upset over this. Yes, this basically ignores customers who install their games to their SSDs. Origin, at the moment, forces all games to be installed in a single directory (albeit that can be anywhere) unlike Steam, which allows games to be individually sent to multiple folders. It would be a good idea to keep those customers in mind... but not at the expense of the game itself. Like always, both "high-end" and "unoptimized" titles have high minimum specifications; we decide which one applies by considering how effectively the performance is used.
That is something that we will need to find out when it launches on March 11th.

You don't often see performance scaling as clean as what Phoronix saw when testing the effect of memory speed on AMD's A10-7850K. Pick any result and you can clearly see a smooth increase in performance from DDR3-800 to DDR3-2400. The only time that increase seems to decline slightly is between DDR3-2133 and 2400MHz, with some tests showing little to no increase between those two speeds. Some tests do still show an improvement, for certain workloads on Linux the extra money is worth it but in other cases you can save a few dollars and limit yourself to the slightly cheaper DDR3-2133. Check out the full review here.
"Earlier in the week I published benchmarks showing AMD Kaveri's DDR3-800MHz through DDR3-2133MHz system memory performance. Those results showed this latest-generation AMD APU craving -- and being able to take advantage of -- high memory frequencies. Many were curious how DDR3-2400MHz would fair with Kaveri so here's some benchmarks as we test out Kingston's HyperX Beast 8GB DDR3-2400MHz memory kit."
