Heads up Vulkan testers, Nvidia has updated their beta Vulkan driver for Linux. It should work better with newer kernels too.
Go to Nvidia's site here for the details. Article taken from GamingOnLinux.com.
QuoteFebruary 23rd, Windows 356.43, Linux 355.00.28
Add support for 64-bit vertex attribute formats
Improve performance of vkBindBufferMemory, vkBindImageMemory and vkCreateGraphicsPipelines
No longer enumerate Fermi based GPUs in vkEnumeratePhysicalDevices
Improved compatibility with recent Linux kernels

Quoting: omer666Quoting: dubigrasuI have some promising results with this new driver, as in Vulkan is already faster:Great results indeed!
OpenGL
Average: 81.4 FPS (86.1 w/o extremes)
Extremes: 254.6 max, 30.6 min
Highs: 523 in 3.5 seconds (150.4 FPS)
Lows: 738 in 14.5 seconds (51.0 FPS
30-60 FPS: 14%
+ 60 FPS: 86%
Vulkan
Average: 88.6 FPS (89.3 w/o extremes)
Extremes: 405.7 max, 9.0 min
Highs: 74 in 0.5 seconds (144.2 FPS)
Lows: 64 in 1.5 seconds (42.5 FPS)
+ 60 FPS: 100%
That was the Talos Principle benchmark BTW.
Funny, I just noticed that I had the Steam FPS counter activated. With it I have 56.1 FPS with Vulkan (Talos Benchmark 60sec). When deactivated the Benchmark counts 70.9 FPS. In OpenGL mode there is almost no difference in FPS. So however it does that, its not good for Vulkan performance in the Talos principle.

Quoting: KeyrockStill no vulkan driver in an Ubuntu 15.10 PPA *sniff sniff* :(Indeed strange to see the actual version being treated worse than the LTS version which is almost 2 years old and should be most stable and secure but not experimental.
Oh well, by the time there is any compelling reason to run a Vulkan driver, 16.04 might already be fully released and I'll be runningsudo do-release-upgrade. :P

Indeed, the Steam Overlay affects Vulkan performance. I disable it entirely for my tests.

What I find interesting is the difference between GL and Vulkan..

It's probably not that interesting. I don't understand the inner workings of Vulkan, but very likely the overlay screws with the communication with the GPU right now. That's probably something Valve will fix in the longer term.

I still think you missunderstood the usage of "wrapper" in this context. They wrapped the engine around Vulkan, which is totally reasonable, not e. g. Vulkan around OpenGL or something. In the end, the engine will still sit on Vulkan. Or be "wrapped around it" if you want to express it that way.

Well, it still uses only one thread for pretty much the whole game, which is the opposite of what you want to get out of Vulkan.. Even with GL it uses two threads. So there should be room for optimizations..
