Valve just recently published a new Steam beta, and they have fixed up the Steam Overlay rendering issue that was causing it to bring down Vulkan performance.
I've run some fresh tests as requested on my Nvidia 980ti to show you the difference now with the Steam Overlay on and being used (FPS counter) vs before.
You can click the spoiler tags to expand the full output if that tickles your fancy.
Just Vulkan
All together
You can see Valve has made the Steam Overlay not impact performance really at all, so that's fantastic news. This is great, as when more games begin to use Vulkan there shouldn't be issues like this (hopefully).
The OpenGL performance has stayed the same as there wasn't really an issue with the Steam Overlay and OpenGL.
4K
Vulkan Average: 112.5 FPS (before it was 75.1 FPS)
OpenGL Average: 91.8 FPS
1080p
Vulkan Average: 136.4 FPS (before it was 82.7 FPS)
OpenGL Average: 102.7 FPS
When there are other games available that use Vulkan, I will most likely take a look at benchmarking them. Article taken from GamingOnLinux.com.

Why is this site so anti AMD? I find that almost no1 mentions performance numbers with AMD cards here? They do have a Vulkan driver out, it works only on Kernel4.2 thought.

Quoting: TheRiddickWhy is this site so anti AMD? I find that almost no1 mentions performance numbers with AMD cards here? They do have a Vulkan driver out, it works only on Kernel4.2 thought.So post your performance numbers or ask someone with suitable hardware to post them. Liam runs Nvidia hardware—just like the majority of us—as it generally works best for Linux gaming at this point. That doesn't make this site anti anything. You're reading the wrong blog if you expect wide hardware coverage in every test.
