Though I am away from my stacks of hardware at the office attending Mobile World Congress in Barcelona, Valve dropped a bomb on us today in the form of a new hardware performance test that gamers can use to determine if they are ready for the SteamVR revolution. The aptly named "SteamVR Performance Test" is a free title available through Steam that any user can download and run to get a report card on their installed hardware. No VR headset required!
And unlike the Oculus Compatibility Checker, the application from Valve runs actual game content to measure your system. Oculus' app only looks at the hardware on your system for certification, not taking into account the performance of your system in any way. (Overclockers and users with Ivy Bridge Core i7 processors have been reporting failed results on the Oculus test for some time.)
The SteamVR Performance Test runs a set of scenes from the Aperture Science Robot Repair demo, an experience developed directly for the HTC Vive and one that I was able to run through during CES last month. Valve is using a very interesting new feature called "dynamic fidelity" that adjusts image quality of the game in a way to avoid dropped frames and frame rates under 90 FPS in order to maintain a smooth and comfortable experience for the VR user. Though it is the first time I have seen it used, it sounds similar to what John Carmack did with the id Tech 5 engine, attempting to balance performance on hardware while maintaining a targeted frame rate.
The technology could be a perfect match for VR content where frame rates above or at the 90 FPS target are more important than visual fidelity (in nearly all cases). I am curious to see how Valve may or may not pursue and push this technology in its own games and for the Vive / Rift in general. I have some questions pending with them, so we'll see what they come back with.
A result for a Radeon R9 Fury provided by AMD
Valve's test offers a very simple three tiered breakdown for your system: Not Ready, Capable and Ready. For a more detailed explanation you can expand on the data to see metrics like the number of frames you are CPU bound on, frames below the very important 90 FPS mark and how many frames were tested in the run. The Average Fidelity metric is the number that we are reporting below and essentially tells us "how much quality" the test estimates you can run at while maintaining that 90 FPS mark. What else that fidelity result means is still unknown - but again we are trying to find out. The short answer is that the higher that number goes, the better off you are, and the more demanding game content you'll be able to run at acceptable performance levels. At least, according to Valve.
Because I am not at the office to run my own tests, I decided to write up this story using results from a third part. That third party is AMD - let the complaining begin. Obviously this does NOT count as independent testing but, in truth, it would be hard to cheat on these results unless you go WAY out of your way to change control panel settings, etc. The demo is self run and AMD detailed the hardware and drivers used in the results.
- Intel i7-6700K
- 2x4GB DDR4-2666 RAM
- Z170 motherboard
- Radeon Software 16.1.1
- NVIDIA driver 361.91
- Win10 64-bit
|2x Radeon R9 Nano||11.0|
|GeForce GTX 980 Ti||11.0|
|Radeon R9 Fury X||9.6|
|Radeon R9 Fury||9.2|
|GeForce GTX 980||8.1|
|Radeon R9 Nano||8.0|
|Radeon R9 390X||7.8|
|Radeon R9 390||7.0|
|GeForce GTX 970||6.5|
These results were provided by AMD in an email to the media. Take that for what you will until we can run our own tests.
First, the GeForce GTX 980 Ti is the highest performing single GPU tested, with a score of 11 - because of course it goes to 11. The same score is reported on the multi-GPU configuration with two Radeon R9 Nanos so clearly we are seeing a ceiling of this version of the SteamVR Performance Test. With a single GPU score of 9.2, that is only a 19% scaling rate, but I think we are limited by the test in this case. Either way, it's great news to see that AMD has affinity multi-GPU up and running, utilizing one GPU for each eye's rendering. (AMD pointed out that users that want to test the multi-GPU implementation will need to add the -multigpu launch option.) I still need to confirm if GeForce cards scale accordingly. UPDATE: Ken at the office ran a quick check with a pair of GeForce GTX 970 cards with the same -multigpu option and saw no scaling improvements. It appears NVIDIA has work to do here.
Moving down the stack, its clear why AMD was so excited to send out these early results. The R9 Fury X and R9 Fury both come out ahead of the GeForce GTX 980 while the R9 Nano, R9 390X and R9 390 result in better scores than NVIDIA's GeForce GTX 970. This comes as no surprise - AMD's Radeon parts tend to offer better performance per dollar when it comes to benchmarks and many games.
There is obviously a lot more to consider than the results this SteamVR Performance Test provides when picking hardware for a VR system, but we are glad to see Valve out in front of the many, many questions that are flooding forums across the web. Is your system ready??

On Christmas Day, Valve had a few hours of problems. Their servers were being overloaded by malicious traffic. The best analogy that I could provide would be a bad organization who sent a thousand people to Walmart, to do nothing but stand in the check-out line and ask the cashier about the time. This clogs up the infrastructure, preventing legitimate customers from making their transactions. This was often done after demanding a ransom. Don't pay? Your servers get clogged at the worst time.
A little too much sharing...
There are two ways to counter-act a DDoS attack: add hardware or make your site more efficient.
When a website is requested, the server generates the page and sends it to the customer. This process is typically slow, especially for complicated sites that pull data from one or more database(s). It then feeds this data to partners to send to customers. Some pages, like the Steam Store's front page, are mostly the same for anyone who views it (from the same geographic region). Some pages, like your order confirmation page, are individual. You can save server performance by generating the pages only when they change, and giving them to relevant users from the closest delivery server.
Someone, during a 20-fold spike in traffic relative to the typical Steam Sale volume, accidentally started saving (caching) pages with private information and delivering them to random users. This includes things like order confirmation and contact information pages for whatever logged-in account generated them. This is pretty terrible for privacy. Again, it does not allow users to interact with the profiles of other users, just see the results that other users generated.
But this is still quite bad.
Users complained, especially on Twitter, that Valve should have shut down their website immediately. From my position, I agree, especially since attempting to make a purchase tells the web server to pull the most sensitive information (billing address, etc.) from the database. I don't particularly know why Valve didn't, but I cannot see that from the outside.
But again, I don't work there. I don't know the details.

I'm not sure how useful this is, but Valve has added the ability to remove a game from your Steam account through their customer support website. When you log into Steam with your web browser, or select “Steam Support” from the Steam Client's Help menu, you can select a game and see its available options. One is “I want to permanently remove this game from my account.”
I don't exactly know all of the specifics for will happen when you do this, but it sounds like you will need to repurchase the title if you change your mind. This is probably most useful for free little experiences, like Portal Story: Mel or Dr. Langeskov, The Tiger, and The Terribly Cursed Emerald: A Whirlwind Heist, which you've completed and don't want cluttering your Steam library.
On the other hand, users at NeoGAF, who (of course) broke this story, are concerned that it will be abused by trolls who phish accounts. Not only can they sell off their items, they can delete all of their games just because. I would hope that Valve has methods to track deleted games, even just for a limited time, in extreme cases.
On the other hand, a service like GoG could benefit from this feature. Since everything is DRM free, it could provide a transaction and let the user delete the record after they purchase it, rather than flaunt it on a public profile as Steam sort-of does. In that case, deleting the record wouldn't destroy the content -- just place the burden on the user to back-up.

While everyone's in a turkey and gravy coma, retailers are hoping that you'll feel a bit browsy with your drowsy. Black Friday deals are popping up everywhere; some are good, but some are token at best... including the Black Friday sale on tokens at the local arcade.
Anyway, four (edit: Fixed typo) of the largest PC gaming services are Steam, UPLAY, Origin, and GOG.com. Steam is predictably the largest sale. It's another “Exploration Sale,” which is another way of saying, “Here's a few examples of great deals; browse for crap you like. You might find something cheaper. I dunno.” Speaking of a few examples, Elite Dangerous is now just a third of its price. Grand Theft Auto V is now reduced too, although it's not yet in the impulse buy territory. Call of Duty Black Ops III also received a little chop in price, which is unusual for the franchise. You'll probably want to browse Steam in general, especially if there's a game that you've been eying but couldn't justify buying yet.
UPlay's sale is a bit more... weird. If you played Tropico 5 but put it down before buying the DLC, the pack of boosters is now 75% off ($11 CDN here). Surprisingly, the vast majority of sales have nothing to do with Ubisoft titles, and the three exceptions are from 2013 / 2014.
Origin is a bit more rounded in terms of old and new titles. FIFA 16, released just this fall, is about 40% off where I am. Tomb Raider is in the mid-single digits of dollars. Battlefield Hardline is about $10. Do not buy The Witcher 3 here though, if the Canadian prices carry over to the US. The sale even extends back to Command & Conquer: The Ultimate Collection, NHL 09, and Medal of Honor: Airborne. It just keeps scrolling.
Now for GOG. This is, again, a sale that you should probably browse. If you were interested in The Witcher 3, purchasing it from GOG instead of Steam will get you the same sale but DRM-free. Its new price is $29.99 USD, unless you're Canadian. We get it for $23.49 USD at GOG or $29.99 CDN at Steam. I guess they feel like giving a slightly larger discount to compensate for the lack of turkey-goggles. Browse the “On Sale” tab in the bottom right before you leave too.

Team Fortress 2 switched from a paid game, first seen in The Orange Box bundle, to a free-to-play title. Financially, you could say that it was supported by tips... ... tips of the hat. Some responded with a wag of their finger, but others with a swipe of their credit card. Where was I going with this? Oh right. This game put Valve on the path of microtransactions, which fuels games like DOTA 2 that aren't supported in any other way.
Each of these item payments are done in game however, even Valve games, except for one. Rust has been chosen to introduce Item Stores on Steam. If you go to Rust's store page, you will see a category called “Items available for this game”. Clicking on it brings you to “Rust Item Store”, where you can buy in-game clothing, weapons, and sleeping bags with real money. This feature is not even available on Team Fortress 2 or DOTA 2.
While there has been some parallels drawn between this and the backtracked paid mods initiative, I don't see it. This is not attempting to take third-party content, some of which was plagiarized from free, existing mods, and sell it. This is an attempt to provide a platform for in-game purchases that already exist. If there's a story, I'd say it's how the initiative launched with a third-party game, and not one of Valve's two, popular, free-to-play titles.

In a move that does nothing to inspire confidence in the future of console ports to PC, Warner Bros. has issued a statement apologizing for the continuing issues with Batman: Arkham Knight, announcing the availability of full refunds for anyone who purchased the game on Steam through the end of this year.
The refund offer has no restrictions on play time, allowing those who purchased the game at any time to get their money back. This unprecedented move, coming after the removal of the PC game for sale on Steam and subsequent re-release last week, dooms the PC port of Batman: Arkham Knight. With the announcement Warner Bros. Games appears to be withdrawing support, as they previously had been promising fixes for the problems plaguing the game.
It remains to be seen if Warner has simply decided to cut their losses and rely on console sales for the latest entry in the Batman franchise. The question going forward will be whether Warner attempts to port the next installment to the PC at all after this disastrous release.

Last week we posted a video that looked over the new Valve Steam Controller and I offered some feedback and input on the new hardware. It was interesting, to say the least, and took some getting used to, but in the end I was surprised by how easy some things were, and how different other things felt. It's an interesting experiment for $50 or so, but it definitely is not a product I recommend all of our readers invest in immediately.
But what about the Steam Link device? This second piece of the puzzle is a small unit that sits near your TV or entertainment system, with an HDMI output, USB inputs, integrated wireless connectivity and Ethernet support. The goal is to stream Steam games from your primary PC without the need for a second computer. Instead, much like the NVIDIA GameStream technology that we have seen for a couple years now, the Steam Link receives a video stream from the gaming PC, accepts input from a controller or keyboard/mouse, and loops it all back.
Specifications (from Valve website):
- 1080p resolution at 60 FPS
- Wired 100 Mbit/s Fast Ethernet and Wireless 802.11ac 2x2 (MIMO) networking abilities
- 3 USB 2.0 ports
- Bluetooth 4.0
- HDMI out
- Supports Steam Controller (sold separately,) Xbox One or 360 Wired Controller, Xbox 360 Wireless Controller for Windows, Logitech Wireless Gamepad F710, or keyboard and mouse
In the Box
- Steam Link
- Power cable and adapter
- HDMI 2.0 cable
- Ethernet cable
To get my full take on it, and to see me test out a handful of games using the Steam Link in our office, check out the video above. The short answer is that game streaming technology is still hit or miss: some titles work great others are an immediate turn off. Want to play a fast paced FPS game? You're going to hate it if you have any kind of PC gaming experience already. Maybe you need to catch up on those recent indie games released on the PC but want to sit on your couch? Steam Link will do the trick.
Again, the device is only $50, so it's not a significant investment for most people, and it might be worth trying if you have some time and are interested in checking out the technology out for yourself.

Four months after being pulled from sale due to performance woes, Batman: Arkham Knight is being re-released for PC (along with a new patch containing all of the fixes) on October 28.
Image credit: Warner Bros.
From the official statement:
“At 10 am PDT, Oct. 28th, Batman: Arkham Knight will be re-released for the PC platform. At the same time we’ll also be releasing a patch that brings the PC version fully up-to-date with content that has been released for console (with the exception of console exclusives).
This means that next week, all PC players will have access to Photo Mode, Big Head Mode, Batman: Arkham Asylum Batman Skin, and character selection in combat AR challenges.”
After such a terrible introduction and long absence after its unprecedented removal from sale on Steam, is there any chance Warner Bros. will still attempt to charge full price for the re-released game? Such a move might be considered controversial, but we will have to wait and see as pricing was not announced.

Of course, this quote doesn't include things like promotional images for games. It's a store, so it will promote its products. This is referring to like, Doritos. In response to Microsoft Xbox and Sony PlayStation integrating ads in their service, Valve said that it doesn't make sense for Steam. It might make some short-term money, but it doesn't bring value to the user, it could harm the long-term relationship with the user, and it probably doesn't even sell Doritos.
Doesn't go with Mountain Dew.
In my opinion, it doesn't really matter. An ad-free Steam is nice, but I don't feel it would that it would affect me much as a user (although that would need to be actually measured to be a valid data point). I also think that its lack of effect is a fallacy. When surveyed, the vast majority of people believe that advertisements don't work on them, or just let them know that products exist. They're wrong.
I do believe that it would affect their long term brand perception with customers in general, though. Several brands have tried to get involved in gaming platforms and events, and the inevitable ads and product placement get ridiculed. It makes sense that Valve would avoid that, especially since their brand is what's keeping them on par with their competitors.
What do you think, though? Do you believe that you would mind? Or would you just shrug and ignore them (unless they're obnoxious)?
