With the release of GTX 960 yesterday NVIDIA also introduced a new version of the GeForce graphics driver, 347.25 - WHQL.
NVIDIA states that the new driver adds "performance optimizations, SLI profiles, expanded Multi-Frame Sampled Anti-Aliasing support, and support for the new GeForce GTX 960".
While support for the newly released GPU goes without saying, the expanded MFAA support will help provide better anti-aliasing performance to many existing games, as “MFAA support is extended to nearly every DX10 and DX11 title”. In the release notes three games are listed that do not benefit from the MFAA support, as “Dead Rising 3, Dragon Age 2, and Max Payne 3 are incompatible with MFAA”.
347.25 also brings additional SLI profiles to add support for five new games, and a DirectX 11 SLI profile for one more:
SLI profiles added
- Black Desert
- Lara Croft and the Temple of Osiris
- Zhu Xian Shi Jie
- The Talos Principle
DirectX 11 SLI profile added
- Final Fantasy XIV: A Realm Reborn
The update is also the Game Ready Driver for Dying Light, a zombie action/survival game set to debut on January 27.
Much more information is available under the release notes on the driver download page, and be sure to check out Ryan’s chat with Tom Peterson from the live stream for a lot more information about this driver and the new GTX 960 graphics card.
NVIDIA GeForce 344.11 Driver and GeForce Experience 2.1.2 Released Alongside Maxwell-based GTX 980 and GTX 970

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.

Alongside the NVIDIA SHIELD Tablet launch, the company has released their GeForce 340.52 drivers. This version allows compatible devices to use GameStream and it, also, is optimized for Metro: Redux and Final Fantasy XIV (China).
The driver supports GeForce 8-series graphics cards, and later. As a reminder, for GPUs that are not based on the Fermi architecture (or later), 340.xx will be your last driver version. NVIDIA does intend to provided extended support for 340.xx (and earlier) drivers until April 1st, 2016. But, when Fermi, Kepler, and Maxwell move on to 343.xx, Tesla and earlier will not. That said, most of the content of this driver is aimed at Kepler and later. Either way, the driver itself is available for those pre-Fermi cards.
I should also mention that a user of Anandtech's forums noted the removal of Miracast from NVIDIA documentation. NVIDIA has yet to comment, although it is still very short notice, at this point.

If you have ever wondered what happened to OpenGL games which used to be common then there is a good post to read over on Slashdot. A developer paints an honest and somewhat depressing picture of what it takes to write working OpenGL code in this day and age. In his mind the blame lies squarely on the driver teams at the three major graphics vendors, with different issues with each of them. While officially referred to as Vendors A, B and C anyone even slightly familiar with the market will figure out exactly which companies are being referred to. While this is a topic worthy of ranting comments be aware that this refers specifically to the OpenGL driver, not the DirectX or Mantle drivers and each company has it's own way of making programmers lives difficult, none are without blame.
"Rich Geldreich (game/graphics programmer) has made a blog post on the quality of different OpenGL Drivers. Using anonymous titles (Vendor A: Nvidia; Vendor B: AMD; Vendor C: Intel), he plots the landscape of game development using OpenGL. Vendor A, jovially known as 'Graphics Mafia' concentrates heavily on performance but won't share its specifications, thus blocking any open source driver implementations as much as possible. Vendor B has the most flaky drivers. They have good technical know-how on OpenGL but due to an extremely small team (money woes), they have shoddy drivers. Vendor C is extremely rich."

The Raspberry Pi recently passed its second anniversary, but until now the open source software friendly hardware has had to rely on closed source drivers for graphics processing on the SoC's VideoCore IV GPU.This has now changed thanks to work by Raspberry Pi hacker Simon Hall who has ported over the open source graphics stack from Broadcom's recently open sourced BCM21553 SoC for cell phones to the BCM2835 SoC that powers the Raspberry Pi. In doing so, Mr. Hall has claimed the Raspberry Pi Foundation's $10,000 bounty by using the newly ported open source graphics driver to run Quake III Arena at 1080p (minimum of 20 FPS according to contest rules).
The ported open source driver is not quite as optimized as the closed source version that the Pi currently uses (which allegedly runs Quake III twice as fast), but it is an encouraging start and the base from which the community can flesh out and optimize. The open source graphics driver is likely to be rolled into future OS releases, but for adventurous users that want the open source driver now, Simon Hall has provided step-by-step instructions for getting the driver and using it to run Quake III on the Raspberry Pi blog. Be warned, it is an involved and time consuming process at the moment.
I would like to say congratulations to Simon Hall for the bounty award and thank him for his work in porting the driver to the Raspberry Pi's SoC!
Hopefully this graphics stack breathes new life into the Raspberry Pi and the community takes up the development mantle to improve upon the codebase and pursue new opportunities that the open source nature enables such as a port of Android running on the Pi.

AMD Releases Catalyst 13.11 Beta 9.2 Driver To Correct Performance Variance Issue of R9 290 Series Graphics Cards
Subject: Graphics Cards, Cases and Cooling | November 8, 2013 - 02:41 AM | Tim Verry

AMD recently launched its 290X graphics card, which is the new high-end single GPU solution using a GCN-based Hawaii architecture. The new GPU is rather large and incorporates an updated version of AMD's PowerTune technology to automatically adjust clockspeeds based on temperature and a maximum fan speed of 40%. Unfortunately, it seems that some 290X cards available at retail exhibited performance characteristics that varied from review units.
AMD has looked into the issue and released the following statement in response to the performance variances (which PC Perspective is looking into as well).
Hello, We've identified that there's variability in fan speeds across AMD R9 290 series boards. This variability in fan speed translates into variability of the cooling capacity of the fan-sink. The flexibility of AMD PowerTune technology enables us to correct this variability in a driver update. This update will normalize the fan RPMs to the correct values.
The correct target RPM values are 2200RPM for the AMD Radeon R9 290X "Quiet mode", and 2650RPM for the R9 290. You can verify these in GPU-Z. If you're working on stories relating to R9 290 series products, please use this driver as it will reduce any variability in fan speeds. This driver will be posted publicly tonight.
From the AMD statement, it seems to be an issue with fan speeds from card to card causing the performance variances. With a GPU that is rated to run at up to 95C, a fan limited to 40% maximum, and dynamic clockspeeds, it is only natural that cards could perform differently, especially if case airflow is not up to par. On the other hand, the specific issue pointed out by other technology review sites (per my understanding, it was initially Tom's Hardware that reported on the retail vs review sample variance) is an issue where the 40% maximum on certain cards is not actually the RPM target that AMD intended.
AMD intended for the Radeon R9 290X's fan to run at 2200RPM (40%) in Quiet Mode and the fan on the R9 290 (which has a maximum fan speed percentage of 47%) to spin at 2650 RPM in Quiet Mode. However, some cards 40% values are not actually hitting those intended RPMs, which is causing performance differences due to cooling and PowerTune adjusting the clockspeeds accordingly.
Luckily, the issue is being worked on by AMD, and it is reportedly rectified by a driver update. The driver update ensures that the fans are actually spinning at the intended speed when set to the 40% (R9 290X) or 47% (R9 290) values in Catalyst Control Center. The new driver, which includes the fix, is version Catalyst 13.11 Beta 9.2 and is available for download now.
If you are running a R9 290 or R9 290X in your system, you should consider updating to the latest driver to ensure you are getting the cooling (and as a result gaming) performance you are supposed to be getting.
Catalyst 13.11 Beta 9.2 is available from the AMD website.

Mid-June kicked up a storm of poop across the internet when IGN broke the AMD optimizations for Frostbite 3. It was reported that NVIDIA would not receive sample code for those games until after they launched. The article was later updated with a statement from AMD: "... the AMD Gaming Evolved program undertakes no efforts to prevent our competition from optimizing for games before their release."
Now, I assume, the confusion was caused by then-not-announced Mantle.
And, as it turns out, NVIDIA did receive the code for Battlefield 4 prior to launch. Monday, the company launched their 331.58 WHQL-certified drivers which are optimized for Batman: Arkham Origins and Battlefield 4. According to the release notes, you should even be able to use SLi out of the gate. If, on the other hand, you are a Civilization V player: HBAO+ should enhance your shadowing.
They also added a DX11 SLi profile for Watch Dogs... awkwarrrrrd.
To check out the blog at GeForce.com for a bit more information, check out the release notes, or just head over to the drivers page. If you have GeForce Experience installed, it probably already asked you to update.
