The Talos Principle developers have just released build 260210, the main feature for us is the improvements to their Vulkan rendering system. Also, the stable version now includes Vulkan as standard.

It's an open beta as usual:
QuoteTo install the beta, do this:
- locate the game in the Steam's "Library" panel
- right click and invoke "Properties"
- select the "Betas" tab
- choose "publicbeta"


Changelog:
New features:
- Added Turkish localization.

Bug fixes:
- Improvements and optimizations for Vulkan API.
- Fixed crashes when using Xbox One controller.

See their announcement here.

I will be looking to run some of my own Vulkan tests sometime soon, so stay tuned. I didn't test the previous builds so I wont be able to give you any numbers difference between this version and the last, but I can at least test it vs OpenGL. Article taken from GamingOnLinux.com.

Try this as a startup option:

+gfx_strAPI "VLK"

I had the exact same issue; turns out it's due to the in-game menu. If you start in Vulkan mode, it runs in Vulkan mode.

I'm glad to see that I get the exact same performance that I got under OpenGL, with mostly high, some ultra, settings.

I pretty much cranked everything up except AA before and did some tests and found that perf was about 15-20% higher in Vulkan. It's now about 25% higher with all frames above 60fps, the lows being 72fps.

Although it's interesting to see the results for just a single minute it's also interesting to see the results afterward, since in the first minute of gameplay a lot of things are loading in the background. If you run a longer benchmark (say 2-3 minutes) it's interesting to see how performance changes. One thing to note is that in GL the game will judder, and it would hitch slightly at times. The original Vulkan beta would hitch sometimes but had no judder, and the newest release has no hitching for me.

Edit (for posterity):
Running Ubuntu 15.10
Intel i7 4770k @ 4ghz
GTX 970 SSC w/ Nvidia 364.12

Thanks for this tips!!
I'm now able to test Vulkan. :)

Quoting: GuestI only see OpenGL as an option, no Vulkan. Using 361.42 driver but I'm pretty sure they pushed Vulkan support into this stable version of the driver...
[364.12](https://devtalk.nvidia.com/default/topic/925605/linux/nvidia-364-12-release-vulkan-glvnd-drm-kms-and-eglstreams/) is the first (and only thus far) stable version the the driver that Nvidia has added Vulkan support.

Finally, it's playable.

I think vulkan support starts with 364. Write "vulkaninfo" in terminal to check your vulkan capabilities.
