FreeSync and Frame Pacing Get a Boost

Make sure you catch today's live stream we are hosting with AMD to discuss much more about the new Radeon Software Crimson driver. We are giving away four Radeon graphics cards as well!! Find all the information right here.

Earlier this month AMD announced plans to end the life of the Catalyst Control Center application for control of your Radeon GPU, introducing a new brand simply called Radeon Software. The first iteration of this software, Crimson, is being released today and includes some impressive user experience changes that are really worth seeing and, well, experiencing.

Users will no doubt lament the age of the previous Catalyst Control Center; it was slow, clunky and difficult to navigate around. Radeon Software Crimson changes all of this with a new UI, a new backend that allows it to start up almost instantly, as well as a handful of new features that might be a surprise to some of our readers. Here's a quick rundown of what stands out to me:

  • Opens in less than a second in my testing
  • Completely redesigned and modern user interface
  • Faster display initialization
  • New clean install utility (separate download)
  • Per-game Overdrive (overclocking) settings
  • LiquidVR integration
  • FreeSync improvements at low frame rates
  • FreeSync planned for HDMI (though not implemented yet)
  • Frame pacing support in DX9 titles
  • New custom resolution support
  • Desktop-based Virtual Super Resolution
  • Directional scaling for 2K to 4K upscaling (Fiji GPUs only)
  • Shader cache (precompiled) to reduce compiling-induced frame time variance
  • Non-specific DX12 improvements
  • Flip queue size optimizations (frame buffer length) for specific games
  • Wider target range for Frame Rate Target Control


That's quite a list of new features, some of which will be more popular than others, but it looks like there should be something for everyone to love about the new Crimson software package from AMD.

For this story today I wanted to focus on two of the above features that have long been a sticking point for me, and see how well AMD has fixed them with the first release of Radeon Software.

FreeSync: Low Frame Rate Compensation

I might be slightly biased, but I don't think anyone has done a more thorough job of explaining and diving into the differences between AMD FreeSync and NVIDIA G-Sync than the team at PC Perspective. Since day one of the G-Sync variable refresh release we have been following the changes and capabilities of these competing features and writing about what really separates them from a technological point of view, not just pricing and perceived experiences.

Software Development Debate: Design vs Profile

Subject: General Tech | November 22, 2015 - 02:08 PM |
Tagged: software development

This is article is a bit different from what we normally post, so be sure to give your opinion in the comments if you want to see more of this (or not). You will most often find these types of software development rants on a programmer's personal blog, but I find them interesting so here we go.


There are two camps in software development regarding optimization, each with diehard advocates. One side argues for software to be strictly designed, with decisions needing to be coherent and performance-minded. The other viewpoint claims that optimization should be done after profiling, because you could spend weeks making a fairly useless chunk of code purr like a kitten, and ignore the turkey that's using 99.99% of your resources.

Both sides can also point to situations that validate their opinion. The latter, “don't premature optimize” crowd can show examples where time is wasted because the engineer didn't look before they leaped. One such story comes from Chandler Carruth of Google. One of his first tasks at the company was to review code from Ken Thompson, a “very senior engineer” who created Unix and defined UTF-8. It solved rule-matching with about a 20-fold increase in performance over what they were currently using. When Chandler went to integrate the fix, his colleague mentioned “Yeah, turns out our use-case overwhelmingly hits a single rule, so I just check it first. It's now 100x faster.”

The other crowd says that, even if you can find exactly where poop stinks, you're still polishing a turd. One issue that is commonly pointed to is garbage collection. In memory-managed languages, this process scans through your application to delete unused chunks. Its goal is to remove memory leaks without users needing to carefully manage allocation themselves. The problem is that it necessarily freezes basically every thread and often takes several frames worth of time to complete. As such, you can either live with the bad user experience in real-time applications, or you can carefully design your application to avoid leaking memory. If you take the time to design and architect, it allows you to either choose a framework without garbage collection, or sometimes reduce / eliminate how often it triggers.

So the argument is over-thinking wasting time versus under-planning painting software into corners. As it should be somewhat obvious, both are correct. It's a bad idea to blindly charge into development, and it's good to think about the consequences of what you're doing. At the same time, what you think means nothing if it differs from what you measure, so you need to back up your thoughts with experimentation.

The challenge is to coast the middle for the benefits of both, without falling into the traps on either side.

Intel to Ship FPGA-Accelerated Xeons in Early 2016

Subject: Processors | November 20, 2015 - 06:21 PM |
Tagged: Intel, xeon, FPGA

Designing integrated circuits, as I've said a few times, is basically a game. You have a blank canvas that you can etch complexity into. The amount of “complexity” depends on your fabrication process, how big your chip is, the intended power, and so forth. Performance depends on how you use the complexity to compute actual tasks. If you know something special about your workload, you can optimize your circuit to do more with less. CPUs are designed to do basically anything, while GPUs assume similar tasks can be run together. If you will only ever run a single program, you can even bake some or all of its source code into hardware called an “application-specific integrated circuit” (ASIC), which is often used for video decoding, rasterizing geometry, and so forth.


This is an old Atom back when Intel was partnered with Altera for custom chips.

FPGAs are circuits that can be baked into a specific application, but can also be reprogrammed later. Changing tasks requires a significant amount of time (sometimes hours) but it is easier than reconfiguring an ASIC, which involves removing it from your system, throwing it in the trash, and printing a new one. FPGAs are not quite as efficient as a dedicated ASIC, but it's about as close as you can get without translating the actual source code directly into a circuit.

Intel, after purchasing FPGA manufacturer, Altera, will integrate their technology into Xeons in Q1 2016. This will be useful to offload specific tasks that dominate a server's total workload. According to PC World, they will be integrated as a two-chip package, where both the CPU and FPGA can access the same cache. I'm not sure what form of heterogeneous memory architecture that Intel is using, but this would be a great example of a part that could benefit from in-place acceleration. You could imagine a simple function being baked into the FPGA to, I don't know, process large videos in very specific ways without expensive copies.

Again, this is not a consumer product, and may never be. Reprogramming an FPGA can take hours, and I can't think of too many situations where consumers will trade off hours of time to switch tasks with high performance. Then again, it just takes one person to think of a great application for it to take off.

Blackberry exposes its Privs and the world ... likes it?

Subject: Mobile | November 20, 2015 - 06:23 PM |
Tagged: blackberry, Priv, Android

Could it truly be enough to add a little Android to your Blackberry to bring them back to some form of popularity?  From what this contributor at The Register has to say it could very well be what the company once known as RIM needed.  The Priv is described as the least irritating Android phone they've ever used, which translates to high praise when you are talking about a Blackberry device.  The sliding keyboard is actually useful, the BlackBerry DTek security app is decent but requires a Google account to be linked to the phone, as do many other apps.  Check out the review to see if this is a berry flavoured Lollipop you might actually want a few licks at.


"Other than that, none of which really counts, I think this might be my least disliked Android phone so far. It’s at least as good as the best Android phones I have used, because it’s the same as all other Androids, just minus the garbage often layered on top. And it’s better, because the BlackBerry stuff layered on top is very far from being garbage."

Windows 10 Tool Now Reverted to Build 10240

Subject: General Tech | November 23, 2015 - 08:15 PM |
Tagged: windows 10, microsoft

UPDATE (Nov 24th, 8pm ET): As I was informed, both on Twitter and in the comments, the update has been restored. Apparently the issue was that this tool, when upgrading Windows 10 to Windows 10 1511, accidentally reset four privacy settings to default. They also happened to be four of the less-severe ones, such as whether to allow apps to run in the background and whether settings should sync between devices. It has apparently been fixed and the tool will install the latest version of Windows 10 once more.

Source: Ars Technica

Regardless of your opinion about Windows 10, I'm glad that Microsoft has once again provided a way to force a specific version on your device. Their recent statement, telling users that Windows Update will give them the correct build eventually, is not comforting if someone is failing to receive the update. Is it coming? Or did it block for some reason? I also wonder if the 30-day policy would still be enforced, making clean installs that much more annoying. Turns out it was all hypothetical, and Microsoft was planning on reinstating it instantly, though.

This is a bit surprising and disappointing. When the November 2015 update for Windows 10 went live, existing users could upgrade with Windows Update (if it let them) and the rest could force an in-place upgrade from Windows 7, 8.x, and earlier builds of Windows 10 using the tool. The latter method has apparently been reverted to the original Windows 10 build from July 2015.


This image is getting a lot more use than I intended.

Why? Who knows. They are still offering the update through Windows Update, and Microsoft claims that they have no intention of pulling it. This concerns me, because there are a few situations where Windows 10 updates will get stuck, such as if you get it through Windows Update then uninstall it. I have not seen any report cover the official procedure for this issue. Also, I wonder if there's a way to get past Microsoft's 30-day no-update policy.

According to WinBeta, Microsoft's official statement contains the following: “Microsoft has not pulled the Windows 10 November 10 update. The company is rolling out the November update over time – if you don’t see it in Windows Update, you will see it soon.” (Emphasis not mine.)

We'll probably hear more about this as the week goes on.

Security Professionals Find eDellRoot Superfishy

Subject: Systems | November 23, 2015 - 09:25 PM |
Tagged: dell, superfish, edellroot

The pun was too tempting, but don't take it too seriously even though it's relatively similar. In short, Dell installs a long-lived, root certificate on their machines with a private key that is now compromised (because they didn't exactly protect it too well). This certificate, and the compromised private key, can be used to sign secure connections without needing to be verified by a Certificate Authority. In other words, it adds a huge level of unwarranted trust to phishing and man-in-the-middle attacks.


Dell has not really made any public comment on this issue yet. I don't really count the tweet from Dell Cares, because customer support is a terrible source for basically any breaking news. It's best to wait until Dell brings out an official statement through typical PR channels before assuming what their position is. Regardless of what they say, of course, your security will be heavily reduced until the certificate and eDell plug-in are removed from your device.

I'm really just wondering if Dell will somehow apologize, or stick to their guns.

What the hell Dell?

Subject: General Tech | November 24, 2015 - 12:42 PM |
Tagged: dell, superfish, security, edellroot

As Scott mentioned yesterday, Dell refused to learn from Lenovo's lesson and repeated the exact same mistake with eDellRoot, a self-signed root CA cert with an unknown purpose.  Unlike SuperFish which was to allow targeted ads to be displayed eDellRoot serves an unclear purpose apart from a mention of Microsoft-like "easier customer support" but it exposes you to the exact same security risks as SuperFish does.  You could remove the cert manually, however as it resides in Dell.Foundation.Agent.Plugins.eDell.dll it will return on next boot and can return on fresh Windows installs via Dell driver updates, something which will be of great concern to their business customers.

Dell has finally responded to the issue, "The recent situation raised is related to an on-the-box support certificate intended to provide a better, faster and easier customer support experience. Unfortunately, the certificate introduced an unintended security vulnerability." and provided a process to remove the certificate from the machine permanently in this Word Document.  You can check for the presence of the cert on your machine in those two links. 

However the best was yet to come as researchers have found a second cert as well as an expired Atheros Authenticode cert for BlueTooth and private key on a limited amount of new Dell computers as well.  As Dell made no mention of these additional certificates in their statement to the press it is hard to give them the benefit of the doubt.  The Bluetooth cert will not make you vulnerable to a man in the middle attack however the second cert is as dangerous as eDellRoot and can be used to snoop on encrypted communications.  The second cert was found on a SCADA machine which is, as they say, a bad thing. 

We await Dell's response to the second discovery as well as further research to determine how widespread the new certs actually are.  So far Dell XPS 15 laptops, M4800 workstations, and Inspiron desktops and laptops have been found to contain these security issues.  The chances of you falling victim to a man in the middle attack thanks to these security vulnerabilities are slim but not zero so be aware of them and keep your eyes out for them on your systems.  With Lenovo and Dell both being caught, it will be interesting to see if HP and other large vendors will learn this lesson or if it will take a third company being caught exposing their customers to unnecessary risks.


"A second root certificate and private key, similar to eDellRoot along with an expired Atheros Authenticode cert and private key used to sign Bluetooth drivers has been found on a Dell Inspiron laptop. The impact of these two certs is limited compared to the original eDellRoot cert."

The R9 380X arrives

Subject: Graphics Cards | November 19, 2015 - 01:37 PM |
Tagged: asus, strix, Radeon R9 380X, tonga

The full serving of Tonga in the AMD Radeon R9 380X has 32 compute units, 2048 stream processors, 32 ROPs and 128 texture units which compares favourably to the 23CUs, 1792 stream processors, 32 ROPs and 112 texture units of the existing R9 380.  Memory bandwidth and amount is unchanged, 182GB/sec of memory bandwidth at the stock speed of 5.7GHz effective and the GPU clock remains around 970MHz as well.  The MSRP is to be $230 for the base model.

With the specifications out of the way, the next question to answer is how it fares against the direct competition, the GTX 960 and 970.  That is where this review from [H]ard|OCP comes in, with a look at the ASUS STRIX R9 380X DirectCU II OC, running 1030MHz default and 1050MHz at the push of a button.  Their tests at 1440p were a little disappointing, the card did not perform well until advanced graphics settings were reduced but at 1080p they saw great performance with all the bells and whistles turned up.  The pricing will be key to this product, if sellers can keep it at or below MSRP it is a better deal than the GTX 970 but if the prices creep closer then the 970 is the better value.


"AMD has let loose the new AMD Radeon R9 380X GPU, today we evaluate the ASUS STRIX R9 380X OC video card and find out how it compares to a 4GB GeForce GTX 960 and GeForce GTX 970 for a wide picture of where performance lies at 1440p or where it does not at 1440p considering your viewpoint."

Should you fear SilverPush?

Subject: General Tech | November 20, 2015 - 02:22 PM |
Tagged: security, silverpush, fud

SilverPush has been around for a while but was recently reverse-engineered so that it could be investigated by anyone with an interest in their phones security.  It is software that is often bundled in advertisements or streamed media that takes advantage of your phones the far greater range of audio sensitivity and the fact that you can communicate information via audio signals.  This could allow an app to communicate with your phone without your knowledge, to collect data from your phone or even to provide contextual ads on your phone.

However as you can see from the list of apps which The Register links to, there is not much likelihood that you have an app which has SilverPush enabled installed on your phone and that is the real key.  If you do not have an app which is listening for audio signals on those frequencies then you will not suffer the effects of SilverPush.  The moral of the story is that your phones security starts with you, if you download random free apps and allow them full access to your phone then you should not be surprised by this sort of thing.


"SilverPush's software kit can be baked into apps, and is designed to pick up near-ultrasonic sounds embedded in, say, a TV, radio or web browser advert. These signals, in the range of 18kHz to 19.95kHz, are too high pitched for most humans to hear, but can be decoded by software."

Li-Fi is a new experimental wireless data transmission technology which sends data using the same lights that illuminate the space you are in, at such frequencies and intensities that your brain does not process any change in lighting which your eyes might capture.  It transmits at an incredible speed, under perfect conditions in the the lab they saw 224GBps and recently have successfully transmitted at 1GBps in the field.  Yes, that is 1GB per second of data transfer, light travels rather quickly after all.  There are limits on where this technology can be used, in large spaces signals from different lights could interfere with each other and if you are outside then you will not be able to benefit but for offices and the home this could be rather impressive to behold.  Read more about the researchers and how these lightbulbs could be tied into existing lighting at The Inquirer.

Enermax's Liqmax II 120s is a relatively small AIO watercooler, the radiator is 154x120x27 mm (6.1x0.8x1.0") and will fit on any modern motherboard, Intel or AMD.  The two 120mm fans which come with the cooler are high static pressure fans with the moniker Batwing and have a physical screw on them which allows you to tune the fan speed manually.  Modders Inc were impressed with this cooler, it performed relatively well and quite quietly and the fact thatit sells for $75 doesn't hurt either. 


"When it comes to a new build I always keep cooling in mind. Not every rig I build has custom water reservoirs, custom piping or fancy radiators.

The keyboard market has changed drastically over the past year with the introduction of mainstream mechanical keys and improved LED backlighting features.  Where once the market was not that competitive and only a few major players were offering products we now have a wide variety of brands to choose from.  This makes it hard to stand out in the market without adding extra features to your keyboards, which leads us to the Thermaltake Poseidon RGB.  This particular keyboard has an integrated 32-bit processor which allows you to choose between 16.8 million colors for each key.  The keys use Kailh Brown RGB switches, a less expensive clone of the Cherry MX Brown switches more commonly found on these types of boards.  Find out if they are good enough over at Benchmark Reviews.


"Just a few months ago, full RGB mechanical keyboards were rare beasts, and the inclusion of full per-key RGB lighting commanded a very high price, with some keyboards selling for almost $200.00. Now, prices are coming down rapidly and vendors are starting to compete on features, but how many more features are there left to add?"

Two new SDKs aimed at VR performance join NVIDIA's GameWorks

There is something about this phrase which describes a feature of NVIDIA's newly announced VR SLI that excites the kid in me "multiple GPUs can be assigned a specific eye to dramatically accelerate stereo rendering".  Maybe you can't afford two GPUs per eye but the fact that it would work if you could manage it is rather impressive.  NVIDIA has announced new SDKs specifically aimed at VR design and performance, GameWorks VR and DesignWorks VR.  Epic has announced that Unreal Engine 4.3 will support these new tools and you can grab them from NVIDIA's developer website right now if you so desire.  You can read more about specific features and optimizations these SDKs will provide at this article on The Inquirer.


"The company said at the release of version 1.0 of GameWorks VR and DesignWorks VR that the SDKs will solve the power-guzzling problems associated with complex, immersive VR graphics processing."

ASUS updates the TUF line of motherboards with the ASUS Sabertooth Z170 Mark 1

It has been a while since we saw a new Sabertooth motherboard from the other side of ASUS, The Ultimate Force, up for review but [H]ard|OCP has remedied that with the new Z170 member of this line of products.  It bears the same Thermal Armour design as previous models, adding a small fan that doesn't quite fit in with the overall design of the motherboard.  As well you will notice an absence of a visible CMOS battery, it is indeed buried under the armour.  [H]ard|OCP were less than impressed with the memory subsystem, the board is rated for DDR4 2400MHz DIMMs maximum and no higher.  On the other hand the incredible stability of this board and the amount of features available on this relatively inexpensive Z170 board did garner a Gold Award.  Read the full review to understand the benefits and drawbacks of this motherboard.


"In our opinion ASUS’ TUF series motherboards target the sweet spot in regard to features, price, and performance. TUF motherboards give you more features than most mid-range motherboards but lack certain features found on the high end. The Sabertooth Z170 Mark 1 is the flagship part of the current TUF series."
