AMD has been transitioning their kernel driver from the closed-source fglrx to the open-source AMDGPU driver that was announced last year. This forms the base that both closed and open user-mode drivers will utilize. For the upcoming Ubuntu 16.04 LTS, Canonical has decided to deprecate fglrx and remove it from the system upon upgrade. Users can then choose to install an AMDGPU-based one, or reinstall the Radeon driver. That will need to be done without Canonical's support, though.
It makes sense that they would choose Ubuntu 16.04 to pull the plug. This is the version that Canonical will be maintaining for the next five years, which could give a headache when AMD has spent the last year trying to get rid of it. AMDGPU is a much safer target as the years roll forward. On the other hand, GPUs prior to Fiji will not have the luxury of choosing, because AMD still hasn't announced AMDGPU for
GDC (Update March 9th @ 6pm: Fixed typo) GCN 1.0 and 1.1.

The last couple of days were not too great for software patches. Microsoft released a Windows 10 update that breaks 5K monitors, and NVIDIA's driver bug, mentioned in the last post, was bigger than they realized. It turns out that the issue is not isolated to multiple monitors, but rather had something to do with choosing “Express Install” in the setup screen.
In response, NVIDIA has removed 364.47 from their website. For those who want “Game Ready” drivers with games like “The Division,” NVIDIA has provided a 364.51 beta driver that supposedly corrects this issue. People on the forums still claim to have problems with this driver, but nothing has been confirmed yet. It's difficult to tell whether other issues exist with the drivers, whether users are having unrelated issues that are attributed to the drivers, or if it's just a few hoaxes. ((Update on March 9th @ 12:41pm: Still nothing confirmed, but one of our comments claim that they've experienced issues personally.)) If you are concerned, then you can roll back to 362.00.
Fortunately for me, I chose to clean install 364.47 and have not had any issues with them. I asked a representative from NVIDIA on Twitter whether I should upgrade to 364.51, and he said that a few other bugs were fixed but I shouldn't bother.
If you managed to properly install 364.47, then you should be fine staying there.

This new driver for NVIDIA brings Vulkan support to their current, supported branch. This is particularly interesting for me, because the Vulkan branch used to pre-date fixes for Adobe Creative Cloud, which meant that things like “Export As...” in Photoshop CC didn't work and After Effects CC would crash. They are also WHQL-certified, and they roll in all of the “Game Ready” fixes and optimizations that were released since ~October, which would be mostly new for Vulkan's branch.
... This is going to be annoying to temporarily disable...
Speaking of which, GeForce Game Ready 364.47 drivers is classified as “Game Ready” itself. The four titles optimized with this release are: Tom Clancy's The Division, Need For Speed, Hitman, and Ashes of the Singularity. If you are interested in playing those games, then this driver is what NVIDIA recommends that you use.
Note that an installation bug has been reported, however. When installing with multiple monitors, NVIDIA suggests that you disable all but one during the setup process, but you can safely re-enable them after. For me, with four monitors and a fairly meticulous desktop icon layout, this was highly annoying, but something I've had to deal with over time (especially the last two, beta Vulkan drivers). It's probably a good idea to close all applications and screenshot your icons before running the installer.

AMD's recent “Hotfix” drivers don't seem to mean what NVIDIA's does. In the Green Team's case, they usually fix one or two issues that slipped past QA. While they likely won't break anything, they are probably a bad idea to install if you're not experiencing the listed problems. The changelog on AMD's drivers are significantly longer with a list of known issues that is roughly the same size.
So should you install it? That depends. It's a little less cut-and-dry than NVIDIA's hotfixes, which are only useful for a handful of people. It sounds like the worst known issue is “Game stuttering may be experienced when running two Radeon R9 295X2 graphics cards in CrossFire mode” and “Display corruption may occur on multiple display systems when it has been running idle for some time.” The latter would affect me greatly, because I run four displays and basically never sleep or shutdown (except for updates). On the other hand, it fixes a variety of crash, hang, and flicker issues.
Check it out. If it sounds good, then pick it up. Otherwise, wait for the next Beta or WHQL driver.

NVIDIA has been pushing for WHQL certification for their drivers, but sometimes issues slip through QA, both at Microsoft and their own, internal team(s). Sometimes these issues will be fixed in a future release, but sometimes they push out a “HotFix” driver immediately. This is often great for people who experience the problems, but they should not be installed otherwise.
In this case, GeForce Hotfix driver 361.60 fixes two issues. One is listed as “install & clocking related issues,” which refers to the GPU memory clock. According to Manuel Guzman of NVIDIA, some games and software was not causing the driver to fully wake the memory clock to a high-performance state. The other issue is “Crashes in Photoshop & Illustrator,” which fixes blue screen issues in both software, and possibly other programs that use the GPU in similar ways. I've never seen GeForce Driver 361.43 cause a BSOD in Photoshop, but I am a few versions behind with CS5.5.
Download links are available at NVIDIA Support, but unaffected users should just wait for an official driver in case the patch causes other issues, due to its minimal QA.

Users of notebooks with the GeForce GTX 860M GPU have apparently been experiencing crashes in many new titles. To remedy these issues, NVIDIA has published GeForce Hotfix Driver 359.12. If you do not have the GeForce GTX 860M, and all of your games work correctly, then you probably shouldn't install this. It has not been tested as much as official releases, by either Microsoft or NVIDIA, so other issues could have been introduced and no-one would know.
If you do have that specific GPU though, and you are having problems running certain titles, then you can install the driver now. Otherwise, you can wait for future, WHQL-certified drivers too. Some users are apparently claiming that the issues were fixed, while others complain about crashes in games like Mad Max and Shadow of Mordor.

Tagged: amd, graphics drivers, GCN, terascale
The Graphics Core Next (GCN) architecture is now a minimum requirement for upcoming AMD graphics drivers. If your graphics card (or APU) uses the TeraScale family of microarchitectures, then your last expected WHQL driver is AMD Catalyst 15.7.1 for Windows 7, 8.x, and 10. You aren't entirely left out of Radeon Software Crimson Edition, however. The latest Crimson Edition Beta driver is compatible with TeraScale, but the upcoming certified one will not be.
GCN was introduced with the AMD Radeon HD 7000 series, although it was only used in the Radeon HD 7700 series GPUs and above. The language doesn't seem to rule out an emergency driver release, such as if Microsoft breaks something in a Windows 10 update that causes bluescreens and fire on older hardware, but they also don't say that they will either. NVIDIA made a similar decision to deprecate pre-Fermi architectures back in March of 2014, which applied to the release of GeForce 343 Drivers in September of that year. Extended support for NVIDIA's old cards end on April 1st, 2016.
I wonder why AMD chose a beta driver to stop with, though. If AMD intended to support TeraScale with Crimson, then why wouldn't they keep it supported until at the first WHQL-certified version? If they didn't intend to support TeraScale, then why go through the effort of supporting it with the beta driver? This implies that AMD reached a hurdle with TeraScale that they didn't want to overcome. That may not be the case, but it's the first thing that comes to my mind none-the-less. Probably the best way to tell is to see how people with Radeon HD 6000-series (or lower-end 7000/8000-series) cards work with Radeon Software Crimson Beta.
Likely the last drivers that users with Radeon HD 6000-series graphics need are 15.7.1 or Radeon Software Crimson Edition Beta. We will soon learn which of the two will be best long-term.
Or, of course, you can buy a newer GPU / APU when you get a chance.

In mid-October, NVIDIA announced that Game Ready drivers would only be available through GeForce Experience with a registered email address, which we covered. Users are able to opt-out of NVIDIA's mailing list, though. They said that this would provide early access to new features, chances to win free hardware, and the ability to participate in the driver development process.
Today's announcement follows up on the “win free hardware” part. The company will be giving away $100,000 worth of prizes, including graphics cards up to the GeForce GTX 980 Ti, game keys, and SHIELD Android TV boxes. To be eligible, users need to register with GeForce Experience and use it to download the latest Game Ready driver.
Speaking of Game Ready drivers, the main purpose of this blog post is to share the list of November/December games that are in this program. NVIDIA pledges to have optimized drivers for these titles on or before their release date:
- Assassin's Creed: Syndicate
- Call of Duty Black Ops III
- Civilization Online
- Fallout 4
- Just Cause 3
- Monster Hunter Online
- RollerCoaster Tycoon World
- StarCraft II: Legacy of the Void
- Star Wars Battlefront
- Tom Clancy's Rainbow Six Siege
- War Thunder
As is the case recently, NVIDIA also plans to get every Game Ready driver certified by Microsoft, through Microsoft's WHQL driver certification program.

The GeForce Game Ready 358.50 WHQL driver has been released so users can perform their updates before the Star Wars Battlefront beta goes live tomorrow (unless you already received a key). As with every “Game Ready” driver, NVIDIA ensures that the essential performance and stability tweaks are rolled in to this version, and tests it against the title. It is WHQL certified too, which is a recent priority for NVIDIA. Years ago, “Game Ready” drivers were often classified as Beta, but the company now intends to pass their work through Microsoft for a final sniff test.
Another interesting addition to this driver is the inclusion of OpenGL 2015 ARB and OpenGL ES 3.2. To use OpenGL ES 3.2 on the PC, if you want to develop software in it for instance, you needed to use a separate release since it was released at SIGGRAPH. It has now been rolled into the main, public driver. The mobile devs who use their production machines to play Battlefront rejoice, I guess. It might also be useful if developers, for instance at Mozilla or Google, want to create pre-release implementations of future WebGL specs too.

Apparently users of AMD's Catalyst 15.9 drivers have been experiencing issues. Specifically, “major memory leaks” could be caused by adjusting windows, such as resizing them or snapping them to edges of the desktop. According to PC Gamer, AMD immediately told users to roll back when they found out about the bug.
They have since fixed it with Catalyst 15.9.1 Beta. This subversion driver also fixes crashes and potential “signal loss” problems with a BenQ FreeSync monitor. As such, if you were interested in playing around with the Catalyst 15.9 beta driver, then it should be safe to do so now. I wish I could offer more input, but I just found out about it and it seems pretty cut-and-dry: if you had problems, they should be fixed. The update is available here.
