The Talos Principle beta updated, Vulkan performance improvements & optimizations

Will test this when i get home :)

This is my benchmark - settings 1920x1080 only on high and AA 2x beacuse game crash when i try to change options :/
Spec: nvidia gtx 780 cpu 4870k @3,2 ram 8 gb 1600 Os: SteamOs

Hmmmpfff - only a lack screen when I turn Vulkan on.....
Quite unfortunate :(

Update: The stable build now includes Vulkan as standard.

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

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

I 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.

Using 361.42 driver but I'm pretty sure they pushed Vulkan support into this stable version of the driver...

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

Nope, no such thing as "vulkaninfo" is known to my terminal (using 364.15).
Is it part of any package?
