During an interview that we streamed live with NVIDIA's Tom Petersen this past Thursday, it was confirmed that NVIDIA is not currently working on, or has any current plans to, add support for the VESA-based and AMD-pushed Adaptive Sync portion of the DisplayPort 1.2a specification. To quote directly:
There is no truth [to that rumor of NVIDIA Adaptive Sync support] and we have made no official comments about Adaptive Sync. One thing I can say is that NVIDIA as a company is 100% dedicated to G-Sync. We are going to continue to invest in G-Sync and it is a way we can make the gaming experience better. We have no need for Adaptive Sync. We have no intention of [implementing it]."
To be clear, the Adaptive Sync part of DP 1.2a and 1.3+ are optional portions of the VESA spec that is not required for future graphics processors or even future display scalar chips. That means that upcoming graphics cards from NVIDIA could still be DisplayPort 1.3 compliant without implementing support for the Adaptive Sync feature. Based on the comments above, I fully expect that to be the case.
The ASUS ROG Swift PG278Q G-Sync monitor
With that new information, you can basically assume that the future of variable refresh monitors is going to be divided: one set for users of GeForce cards and one set for users with Radeon cards. (Where Intel falls into this is up in the air.) Clearly that isn't ideal for a completely open ecosystem but NVIDIA has made the point, over and over, that what they have developed with G-Sync is difficult and not at all as simple as could be solved with the blunt instrument that Adaptive Sync is. NVIDIA has a history of producing technologies and then keeping them in-house, focusing on development specifically for GeForce owners and fans. The dream of having a VRR monitor that will run on both vendors GPUs appears to be dead.
When asked about the possibility of seeing future monitors that can support both NVIDIA G-Sync technology as well as Adaptive Sync technology, Petersen stated that while not impossible, he "would not expect to see such a device."
The future of G-Sync is still in development. Petersen stated:
"Don't think that were done. G-Sync is not done. Think of G-Sync as the start of NVIDIA solving the problems for gamers that are related to displays...G-Sync is our first technology that makes games look better on displays. But you can start looking at displays and make a lot of things better."

So now we await for the first round of prototype FreeSync / Adaptive Sync monitors to hit our labs. AMD has put a lot of self-inflicted pressure on itself for this release by making claims, numerous times, that FreeSync will be just as good of an experience as G-Sync, and I am eager to see if they can meet that goal. Despite any ill feelings that some users might have about NVIDIA and some of its policies, it typically does a good job of maintaining a high quality user experience with these custom technologies. AMD will have to prove that what it has developed is on the same level. We should know more about that before we get too much further into fall.

UPDATE: If you missed the live stream yesterday, I have good news: the interview and all the information/demos provided are available to you on demand right here. Enjoy!
Last week NVIDIA launched GM204, otherwise known as Maxwell and now branded as the GeForce GTX 980 and GTX 970 graphics cards. You should, of course, have already read the PC Perspective review of these two GPUs, but undoubtedly there are going to be questions and thoughts circulating through the industry.
To help the community get a better grasp and to offer them an opportunity to ask some questions, NVIDIA's Tom Petersen is stopping by our offices on Thursday afternoon where he will run through some demonstrations and take questions from the live streaming audience.
Be sure to stop back at PC Perspective on Thursday, September 25th at 4pm ET / 1pm PT to discuss the new Maxwell GPU, the GTX 980 and GTX 970, new features like Dynamic Super Resolution, MFAA, VXGI and more! You'll find it all on our PC Perspective Live! page on Monday but you can sign up for our "live stream mailing list" as well to get notified in advance!
NVIDIA Maxwell Live Stream
1pm PT / 4pm ET - September 25th
We also want your questions!! The easiest way to get them answered is to leave them for us here in the comments of this post. That will give us time to filter through the questions and get the answers you need from Tom. We'll take questions via the live chat and via Twitter (follow me @ryanshrout) during the event but often time there is a lot of noise to deal with.
So be sure to join us on Thursday afternoon!
UPDATE: We have confirmed at least a handful of prizes for those of you that tune into the live stream today. We'll giveaway an NVIDIA SHIELD as well as several of the brand new SLI LED bridges that were announced for sale this week!

If you were looking to download EVGA Precision X recently, you were likely disappointed. For a few months now, the software was unavailable because of a disagreement between the add-in board (AIB) partner and Guru3D (and the RivaTuner community). EVGA maintains that it was a completely original work, and references to RivaTuner are a documentation error. As a result, they pulled the tool just a few days after launching X 15.
This new version, besides probably cleaning up all of the existing issues mentioned above, adds support for the new GeForce GTX 900-series cards, a new interface, an "OSD" for inside applications, and Steam Achievements (??). You can get a permanent badge on your Steam account for breaking 1200 MHz on your GPU, taking a screenshot, or restoring settings to default. I expect that latter badge is one of shame, like the Purple Heart from Battlefield, that is not actually a bad thing and says nothing less of your overclocking skills by pressing it. Seriously, save yourself some headache and just press default if things just do not seem right.
PrecisionX 16 is free, available now, and doesn't require an EVGA card (just a site sign-up).

Tagged: tablet, Nexus, google, nexus 9, nvidia, tegra k1
The Nexus line is due for an update, with each product being released for at least a year. They are devices which embody Google's vision... for their own platform. You can fall on either side of that debate, whether it guides OEM partners or if it is simply a shard the fragmentation issue, if you even believe that fragmentation is bad, but they are easy to recommend and a good benchmark for Android.
We are expecting a few new entries in the coming months, one of which being the Nexus 9. Of note, it is expected to mark the return of HTC to the Nexus brand. They were the launch partner with the Nexus One and then promptly exited stage left as LG, Samsung, and ASUS performed the main acts.
We found this out because NVIDIA spilled the beans on their lawsuit filing against Qualcomm and Samsung. Apparently, "the HTC Nexus 9, expected in the third quarter of 2014, is also expected to use the Tegra K1". It has since been revised to remove the reference. While the K1 has a significant GPU to back it up, it will likely be driving a very high resolution display. The Nexus 6 is expected to launch at around the same time, along with Android 5.0 itself, and the 5.2-inch phone is rumored to have a 1440p display. It seems unlikely that a larger, tablet display will be lower resolution than the phone it launches alongside -- and there's not much room above it.
The Google Nexus 9 is expected for "Q3".

The growing market of low cost $200 to $400 10" to 15" laptops is expected to cut into the sales of AMD and NVIDIA's mobile GPUs as they are forced to focus more on higher end models. That is a much smaller market and the margins generally favour the laptop vendor as opposed to the company providing the mobile GPU. This will be felt more strongly by NVIDIA as AMD's APU lineup will appear in the smaller and less expensive notebooks but will still have an effect on AMD's bottom line over the coming quarters. DigiTimes also mentioned that AMD's R9 390X is due out in the first half of 2015 and that both companies are currently reducing the price of their GPUs in the hopes of increasing their sales volumes on the desktop.
"Notebook vendors including Hewlett-Packard (HP), Dell, Lenovo, Asustek Computer, Acer and Toshiba, will launch low-cost models with CPUs with integrated graphics in the fourth quarter of 2014 and therefore AMD and Nvidia are expected to see demand for their discrete mobile GPUs decrease, according to Taiwan-based supply chain makers."

Here they come - the G-Sync monitors are finally arriving at our doors! A little over a month ago we got to review the ASUS ROG Swift PG278Q, a 2560x1440 144 Hz monitor that was the first retail-ready display to bring NVIDIA's variable refresh technology to consumers. It was a great first option with a high refresh rate along with support for ULMB (ultra low motion blur) technology, giving users a shot at either option.
Today we are taking a look at our second G-Sync monitor that will hit streets sometime in mid-October with an identical $799 price point. The Acer XB280HK is a 28-in 4K monitor with a maximum refresh rate of 60 Hz and of course, support for NVIDIA G-Sync.
The Acer XB280HK, first announced at Computex in June, is the first 4K monitor on the market to be announced with support for variable refresh. It isn't that far behind the first low-cost 4K monitors to hit the market, period: the ASUS PB287Q and the Samsung U28D590D both shipped in May of 2014 with very similar feature sets, minus G-Sync. I discussed much of the general usability benefits (and issues) that arose when using a consumer 4K panel with Windows 8.1 in those reviews, so you'll want to be sure you read up on that in addition to the discussion of 4K + G-Sync we'll have today.
While we dive into the specifics on the Acer XB280HK monitor today, I will skip over most of the discussion about G-Sync, how it works and why we want it. In our ASUS PG278Q review I had a good, concise discussion on the technical background of NVIDIA G-Sync technology and how it improves gaming.
The idea of G-Sync is pretty easy to understand, though the implementation method can get a bit more hairy. G-Sync introduces a variable refresh rate to a monitor, allowing the display to refresh at wide range of rates rather than at fixed intervals. More importantly, rather than the monitor dictating what rate this refresh occurs at to the PC, the graphics now tells the monitor when to refresh in a properly configured G-Sync setup. This allows a monitor to match the refresh rate of the screen to the draw rate of the game being played (frames per second) and that simple change drastically improves the gaming experience for several reasons.

SLI Bridges are thrown in with compatible motherboards and there is usually little reason to want anything else. They work. There is no performance advantage for getting a "better" one, unless it does not connect with your specific arrangement of two-to-four cards. Today, NVIDIA gives another reason: a soft, beautiful glow to match the green "GeForce GTX" on the cards themselves.
Mind you, this is not the first glowing SLI Bridge. EVGA even provided us with a few of their own for a giveaway last year.
NVIDIA has three models, depending on the layout of your cards. 3-way SLI will need to be arranged as a series of two-wide with no gaps, using the "3-Way SLI Bridge". 2-way configurations have the choice of two empty slots between the two-wide cards, or no gap; former would purchase the "2-Way Spaced SLI Bridge" and the later, the "2-Way SLI Bridge". They each require GeForce GTX 770 cards, or better, as well as a recent GeForce Experience (1.7+). Certain non-reference designs may be incompatible.
The SLI Bridges are available now. Both 2-Way bridges are $29.99 and the 3-Way is $39.99.
NVIDIA GeForce 344.11 Driver and GeForce Experience 2.1.2 Released Alongside Maxwell-based GTX 980 and GTX 970

Tagged: nvidia, maxwell, graphics drivers, geforce experience
Update: There is also the 344.16 for the GTX 970 and GTX 980, resolving an issue specific to them.
When they release a new graphics card, especially in a new architecture, NVIDIA will have software ready to support it. First and most obvious, Maxwell comes with the GeForce 344.11 drivers - which is the first to support only Fermi and later GPUs. Mostly, the driver's purpose is supporting the new graphics cards and optimizing to Borderlands: The Pre-Sequel, The Evil Within, F1 2014, and Alien: Isolation. It also supports multi-monitor G-Sync, which was previously impossible, even with three single-DisplayPort Kepler cards.
At the same time, NVIDIA launched a new GeForce Experience with more exciting features. First, and I feel least expected, it allows the SHIELD Wireless Controller to be connected to a PC, but only wired with its provided USB cable. This also means that you cannot use the controller without a GeForce graphics card.
If you have a GeForce GTX 900-series add-in board, you will be able to use Dynamic Super Resolution (DSR) and record in 4K video with ShadowPlay. Performance when recording on a PC in SLI mode has been improved also, apparently even for Kepler-based cards.

Tagged: unreal engine 4, nvidia, microsoft, maxwell, DirectX 12, DirectX
Microsoft and NVIDIA has decided to release some information about DirectX 12 (and DirectX 11.3) alongside the launch of the Maxwell-based GeForce GTX 980 and GeForce GTX 970 graphics cards. Mostly, they announced that Microsoft teamed up with Epic Games to bring DirectX 12 to Unreal Engine 4. They currently have two demos, Elemental and Infiltrator, that are up and running with DirectX 12.
Moreover, they have provided a form for developers who are interested in "early access" to apply for it. They continually discuss it in terms of Unreal Engine 4, but they do not explicitly say that other developers cannot apply. UE4 subscribers will get access to the Elemental demo in DX12, but it does not look like Infiltrator will be available.
DirectX 12 is expected to target games for Holiday 2015.
