AMD Catalyst 14.4 RC available for Linux and Windows

AMD has made its Catalyst 14.4 Windows and Linux drivers available for download. This Release Candidate (RC) driver is expected to arrive in its official WHQL form in a week or two but for those who like the look of the #improvements and regularly install beta drivers it may well be appealing. The headline features of this driver include; support for the AMD Radeon R9 295X, enhancements and fixes for people running #CrossFire configured systems and full support for #OpenGL 4.4.

If you have an AMD CrossFire PC gaming system, the new 14.4 RC driver is said to solve problems with Eyefinity 3×1 systems using 3x 4K panels. Also Eyefinity setups with V-sync and mid-Eyefinity resolutions will experience less stuttering problems.

Looking at CrossFire gaming improvements the following positive changes have been made:

  • Crysis 3 – frame pacing improvements
  • Far Cry 3 – 3 and 4 GPU performance improvements at high quality settings, high resolution settings
  • Anno 2070 – Improved CrossFire scaling up to 34%
  • Titanfall – Resolved in game flickering with CrossFire enabled
  • Metro Last Light – Improved Crossfire scaling up to 10%

Some Mantle beta driver improvements have also come along in this Release Candidate driver and have, in particular, fixed the performance slowdown in Battlefield 4 when Alt/Tab task switching. A10 Kaveri system users will also be cured of fuzzy images when playing in a “rotated SLS resolution”.

OpenGL 4.4 now is fully supported in this latest driver from Windows and Linux. However Linux users don’t get the CrossFire gaming and Mantle enhancements listed above. Read more about the extensions supported here.

Finally there are still some known issues which haven’t been fixed in time for this driver release. These include crashes in Power Director 11 and install problems on Dual AMD Radeon R9 295X systems running Windows 8.1 with the following motherboards: ASUS Crosshair V Formula-Z (990FX), ASUS Maximus VI Extreme (Z87), ASUS Rampage IV Extreme (X79). On those configurations the driver will continue to install after a black-screen hang followed by a simple reboot.

Now Available AMD Catalyst 14.2 Beta V 1.3 with Brings Mantle Updates

AMD has released #Catalyst 14.2 Beta Version 1.3 drivers today for Windows users to coincide with the North American launch of THIEF! That means this is the game ready driver, and it’s an exclusive partner of the AMD #Gaming Evolved program. Throughout development of the PC and console versions of the game, this game title was built with AMD Radeon products in mind. At launch, AMD Radeon customers will have day-one support for: 4K gaming, AMD Eyefinity technology, AMD CrossFire technology and advantageous DirectX 11 performance. In addition, everyone will benefit from the Square/AMD collaboration through a host of graphical effects:

  • Compute shader-accelerated depth of field for realistic focal lengths
  • Silhouette-enhancing tessellation to improve character geometry
  • Complex shadowing systems to support THIEF’s dependence on shadows as a core gameplay mechanic. This is a great example of rendering technology supporting an integral element of the game! A notable percentage of the game’s rendering budget has been spent on the novel shadowing algorithms.
  • SSAA for buttery smooth edges.

THIEF will be patched to support Mantle and AMD TrueAudio technologies in early March.

Where are the Linux drivers? AMD hasn’t forgotten about Linux gamers and did tell us about some interesting driver developments that are currently taking place on that side of the house. AMD has submitted the following changes to the X.ORG ‘radeon’ repository—our open source driver (OSS Linux Radeon driver):

  • Video Compression Engine (VCE) enabled for  compatible GPU and APU products (e.g. GCN-based SKUs). Hardware-accelerated encode of H.264 now possible for 1080p60 content
  • Video decode (UVD) performance and efficiency improvements for the AMD R9 290/290X, R9 260X, “Kaveri” and “Kabini”
  • X-Video hardware video acceleration via the GLAMOR library now supported
  • 2D acceleration via the GLAMOR library now enabled by default
  • Substantial improvements to overall video transcode times for hardware-accelerated transcoding apps
  • Tiling support now enabled on all GCN-based products
  • Substantial OpenGL feature level upgrade to v4.3
  • Major contributions to the Linux kernel 3.14 to improve dynamic power management, DisplayPort robustness and power efficiency on all GCN-based hardware
  • New programming guides and register specifications released for HD 5000, 6000, 7000 and R9/R7 Series GPUs. This will enable volunteer and professional developers to contribute to the X.ORG OSS Radeon driver, and can facilitate porting to other non-Linux platforms.

NVIDIA hints at support for Linux open source 'Nouveau' driver

NVIDIA support for Linux open source 'Nouveau' driver

NVIDIA has shocked the open source world with a welcome surprise. Alexandre Courbot announced through the Free Desktop group’s xdg mailing list that the GPU chip maker is providing more support for the Linux world’s open source Nouveau driver for NVIDIA cards.

Just a few years ago, anyone wanting to play games on their PC were almost exclusively locked into the Windows operating system. Valve decided to work on changing that by making Steam available for Linux and eventually basing their upcoming SteamOS on Linux. NVIDIA’s taken notice of the reception Steam’s had in the Linux world and is now working with other open source developers to better support their upcoming Tegra K1 chip.

At the moment, there are no plans to expand the company’s experimental Nouveau work. Courbot advises *nix users not to uninstall the proprietary nv driver just yet with a winking smilie face. It’s possible that there may be plans to further improve the nv driver so *nix gamers can continue to take advantage of the growing number of games making their way to the open source world.

“I guess my email address might surprise some of you, so let me anticipate some questions you might have. 😛 Yes, this work is endorsed by NVIDIA. Several other NVIDIAns (CC’d), including core GPU experts, have provided significant technical guidance and will continue their involvement. Special thanks go to Terje Bergstrom and Ken Adams for their invaluable GPU expertise, and Thierry Reding (at FOSDEM this weekend) for help with debugging and user-space testing.

“Let me also stress that although very exciting, this effort is still experimental, so I would like to make sure that nobody makes excessive expectations based on these few patches. The scope of this work is strictly limited to Tegra (although given the similarities desktop GPU support will certainly benefit from it indirectly), and we do not have any plan to work on user-space support. So do not uninstall that proprietary driver just yet. ;)”

Valve's SteamOS, AMD and Nvidia Gear up Linux driver support

Well, that didn’t take long. Less than a day after Valve announced SteamOS, the Linux-based operating system based around the incredibly popular Steam PC gaming service, both AMD and Nvidia stepped up their driver support for the open-source OS.Driver support for graphics cards can be a major stumbling block for would-be Linux gamers. Since fewer people use Linux (and most games are created with Windows in mind), driver support for the operating system can be a bit, well, hit-or-miss.

AMD

AMD has actually been pretty active in the Linux community in recent memory, though its open-source Linux drivers still lag behind its Windows drivers. Just a few months back, the company released a massive set of 165 kernel patches that enabled some key features in Linux Radeon drivers, such as dynamic power management and initial support for the “Sea Islands” family of GPUs.

Valve's SteamOS, AMD and Nvidia Gear up Linux driver support
Steam for Linux has been available since February and offers around 200 games.

AMD’s holding a GPU showcase in Hawaii on Wednesday. A new series of graphics cards are almost certainly going to be the stars of the show, but corporate VP Raja Koduri said there will also be news concerning Linux driver support, according to AnandTech. The AMD GPU showcase is expected to start around the same time that Valve unveils its second Steam-related announcement for the week.

Nvidia

Nvidia’s relationship with Linux has been a bit more, shall we say, tense.

In July 2012, after a woman at a group chat session described her frustrations trying to use Nvidia’s power-saving Optimus technology, Linux creator Linus Torvalds launched into an expletive-riddled tirade.

Nvidia Gear up Linux driver support for SteamOS

“Nvidia has been the single worst company we’ve dealt with,” he said, before turning towards the video camera and extending his middle finger. “Nvidia… F*** you!” he hissed, uttering the words slowly and sharply.

To be fair, Nvidia does a decent job of supplying basic (or better!) Linux drivers for its latest graphics cards, and the company took issue with the remarks. Nvidia’s drivers, however, are closed source, and unlike AMD, it hasn’t traditionally offered open source drivers or documentation, which doesn’t sit well with fanatical Linux lovers.

That changed on Monday—the same day SteamOS was announced.

That day, Nvidia’s Andy Ritger messaged members of Noveau—the group that reverse-engineers Nvidia’s closed-source Linux drivers to create an open-source alternative—and said Nvidia developers working on the closed-sourced Linux GPU drivers will start paying attention to the Noveau mailing group, offering assistance when possible. Additionally, Ritger said Nvidia will provide more official help:

NVIDIA is releasing public documentation on certain aspects of our GPUs, with the intent to address areas that impact the out-of-the-box usability of NVIDIA GPUs with Nouveau. We intend to provide more documentation over time, and guidance in additional areas as we are able .

ArsTechnica coaxed Torvalds out of his shell to comment.

“I’m cautiously optimistic that this is a real shift in how Nvidia perceives Linux,” the Linux creator said. “The actual docs released so far are fairly limited, and in themselves they wouldn’t be a big thing, but if Nvidia really does follow up and start opening up more, that would certainly be great.”

A sign of things to come?

SteamOS

Amittedly, these are baby steps down a long road. It’s still too soon to know if Valve’s new endeavor will be a success, and you definitely can’t call 2013 the oft-dreamed-for “Year of the Linux desktop” just yet, but one thing is for certain: SteamOS is already making an impact on Linux gaming, and AMD and Nvidia’s driver support will only get better if the Steam Box concept takes off in the living room. (Here’s how to make your own Steam Box if you’re interested.)
