Yesterday, NVIDIA has released WHQL-certified drivers to align with the release of Overwatch. This version, 368.22, is the first public release of the 367 branch. Pascal is not listed in the documentation as a supported product, so it's unclear whether this will be the launch driver for it. The GTX 1080 comes out on Friday, but two drivers in a week would not be unprecedented for NVIDIA.
While NVIDIA has not communicated this too well, 368.22 will not install on Windows Vista. If you are still using that operating system, then you will not be able to upgrade your graphics drivers past 365.19. 367-branch (and later) drivers will required Windows 7 and up.
Before I continue, I should note that I've experienced so issues getting these drivers to install through GeForce Experience. Long story short, it took two attempts (with a clean install each time) to end up with a successful boot into 368.22. I didn't try the standalone installer that you can download from NVIDIA's website. If the second attempt using GeForce Experience failed, then I would have. That said, after I installed it, it seemed to work out well for me with my GTX 670.
While NVIDIA is a bit behind on documentation, the driver also rolls in other fixes. There were some GPU compute developers who had crashes and other failures in certain OpenCL and CUDA applications, which are now compatible with 368.22. I've also noticed that my taskbar hasn't been sliding around on its own anymore, but I've only been using the driver for a handful of hours.
You can get GeForce 368.22 drivers from GeForce Experience, but you might want to download the standalone installer (or skip a version or two if everything works fine).

For the second time this month, hence the version number, AMD has released a driver to coincide with a major game release. This one is for DOOM, which will be available on Friday. Like the previous driver, which was aligned with Forza, it has not been WHQL-certified. That's okay, though. NVIDIA's Game Ready drivers didn't strive for WHQL certification until just recently, and, even then, WHQL certification doesn't mean what it used to.
But yeah, apart from game-specific optimizations for DOOM, 16.5.2 has a few extra reasons to be used. If you play Battleborn, which launched on May 3rd, then AMD has added a new CrossFire profile for that game. They have also fixed at least eleven issues (plus however many undocumented ones). It comes with ten known issues, but none of them seem particularly troubling. It seems to be mostly CrossFire-related issues.
You can pick up the driver at AMD's website.

This is good to see. AMD has released Radeon Software Crimson Edition 16.5.1 to align with Forza Motorsport 6: Apex. The drivers are classified as Beta, and so is the game, coincidentally, which means 16.5.1 is not WHQL-certified. That doesn't have the weight that it used to, though. Its only listed feature is performance improvements with that title, especially for the R9 Fury X graphics card. Game-specific optimizations near launch appear to be getting consistent, and that was an area that AMD really needed to improve upon, historically.
There are a handful of known issues, but they don't seem particularly concerning. The AMD Gaming Evolved overlay may crash in some titles, and The Witcher 3 may flicker in Crossfire, both of which could be annoying if they affect a game that you have been focusing on, but that's about it. There might be other issues (and improvements) that are not listed in the notes, but that's all I have to work on at the moment.
If you're interested in Forza 6: Apex, check out AMD's download page.

The GeForce 364.xx line of graphics drivers hasn't been smooth for NVIDIA. Granted, they tried to merge Vulkan support into their main branch at the same time as several new games, including DirectX 12 ones, launched. It was probably a very difficult period for NVIDIA, but WHQL-certified drivers should be better than this.
Regardless, they're trying, and today they released GeForce Hot Fix Driver 364.96. Some of the early reactions mock NVIDIA for adding “Support for DOOM Open Beta” as the only listed feature of a “hotfix” driver, but I don't see it. It's entirely possible that the current drivers have a known issue with DOOM Open Beta and, thus, they require a hotfix. It's not necessarily “just a profile,” and “profiles” isn't exactly what a hardware vendor does to support a new title.
But anyway, Manuel Guzman, one of the faces for NVIDIA Customer Care, also says that this driver includes fixes for FPS drops in Dark Souls 3. According to some forum-goers, despite its numbering, it also does not contain the Vulkan updates from 364.91. This is probably a good thing, because it would be a bit silly to merge developer-branch features into a customer driver that only intends to solve problems before an official driver can be certified. I mean, that's like patching a flat tire, then drilling a hole in one of the good ones to mess around with it, too.
The GeForce 364.96 Hotfix Drivers are available at NVIDIA's website. If you're having problems, then it might be your solution. Otherwise? Wait until NVIDIA has an official release (or you start getting said problems).

This is not a main-line, WHQL driver. This is not even a mainstream beta driver. The beta GeForce 364.91 drivers (364.16 on Linux) are only available on the NVIDIA developer website, which, yes, is publicly accessible, but should probably not be installed unless you are intending to write software and every day counts. Also, some who have installed it claim that certain Vulkan demos stop working. I'm not sure whether that means the demo is out-of-date due to a rare conformance ambiguity, the driver has bugs, or the reports themselves are simply unreliable.
That said, if you are a software developer, and you don't mind rolling back if things go awry, you can check out the new version at NVIDIA's website. It updates Vulkan to 1.0.8, which is just documentation bugs and conformance tweaks. These things happen over time. In fact, the initial Vulkan release was actually Vulkan 1.0.3, if I remember correctly.
The driver also addresses issues with Vulkan and NVIDIA Optimus technologies, which is interesting. Optimus controls which GPU acts as primary in a laptop, switching between the discrete NVIDIA one and the Intel integrated one, depending on load and power. Vulkan and DirectX 12, however, expose all GPUs to the system. I'm curious how NVIDIA knows whether to sleep one or the other, and what that would look like to software that enumerates all compatible devices. Would it omit listing one of the GPUs? Or would it allow the software to wake the system out of Optimus should it want more performance?
Anywho, the driver is available now, but you probably should wait for official releases. The interesting thing is this seems to mean that NVIDIA will continue to release non-public Vulkan drivers. Hmm.

New graphics drivers from AMD have just been published, and it's a fairly big release. First, Catalyst 16.3 adds Vulkan support to main-branch drivers, which they claim is conformant to the 1.0 specification. The Khronos Group website still doesn't list AMD as conforming, but I assume that they will be added shortly (rather than some semantic “conformant” “fully conformant” thing going on). This is great for the platform, as we are still in the launch window of DirectX 12.
Performance has apparently increased as well, significantly. This is especially true in the DirectX 12 title, Gears of War Ultimate Edition. AMD claims that FuryX will see up to a 60% increase in that title, and the R9 380 will gain up to 44%. It's unclear how much that is in real world performance, especially in terms of stutter and jank, which apparently plagues that game.
The driver also has a few other interesting features. One that I don't quite understand is “Power Efficiency Toggle”. This supposedly “allows the user to disable some power efficiency optimizations”. I would assume that means keeping you GPU up-clocked under certain conditions, but I don't believe that was much of an issue for the last few generations. That said, the resolved issues section claims that some games were choppy because of core clock fluctuation, and lists this option as the solution, so maybe it was. It is only available on “select” Radeon 300 GPUs and Fury X. That is, Fury X specifically, not the regular Fury or the Nano. I expect Ryan will be playing around with it in the next little while.
Last of the main features, the driver adds support for XConnect, which is AMD's new external graphics standard. It requires a BIOS that support external GPUs, which AMD lists the Razer Blade Stealth as. Also noteworthy, Eyefinity can now be enabled with just two displays, and Display Scaling can be set per-game. I avoid manually controlling drivers, even my Wacom tablet, to target specific applications, but that's probably great for those who do.
As a final note: the Ashes of the Singularity 2.0 benchmark now supports DirectFlip.
If you have a recent AMD GPU, grab the drivers from AMD's website.

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.
