I decided to take a look at this Vulkan nonsense with The Talos Principle, since I hadn't actually tried it yet myself. Here are some benchmarks done on my 980ti. I will look to do some on my 970 if people want to see them too.
Tested across two different driver versions, both at 4K and 1080p using the built-in benchmark tool. This is using the beta version of Talos, not the stable version.
From my observations Vulkan seems smoother, with little to no hitching/stutters, where as OpenGL did show some notable hitching/stutters for brief moments.
It seems that the Steam Overlay brings down the overall Vulkan performance if something is using it. If you have the FPS counter on, or you get notifications the Vulkan performance will go down. For best results, turn it off. Valve are aware of the Steam Overlay rendering issue.
Test done on Intel i7, Nvidia 980ti, 16GB RAM, standard hard drive for the game as my SSD is used for my OS. You can click each spoiler section for the full benchmark log from the game.
Game settings for all tests:

Quoting: Purple Library GuyWell, and correct me if I'm wrong but I seem to recall hearing that PS4 will run Vulkan . . .
If you go by the supporters list, Nintendo may support Vulkan with their upcoming NX console too.

I did other tests after updating Steam.
OS: Debian 8.4 (Jessie) - 3.16.0-4-amd64
CPU: i5 3570K
RAM: 8GB
GPU: Nvidia 660GTX - 364.15
Here are results I got yesterday:
Steam Overlay enabled: OpenGL 82fps - Vulkan 58fps
Steam Overlay disabled: OpenGL 83fps - Vulkan 107fps
Here are results I got today:
Steam Overlay enabled: OpenGL 82fps - Vulkan 107fps
Steam Overlay disabled: OpenGL 83fps - Vulkan 107fps
Steam Overlay has now no impact with Vulkan rendering on my system.
I also did the full benchmark test (184 sec) on Vulkan with Steam Overlay enabled to see if there is any downside, and I got 114 fps in average. ^_^

Just now i finished the Talos Principle with Vulkan :D
I climped the tower. Nice ending.
Started it a few weeks ago with OpenGL and switch to Vulkan as soon as the nvidia driver got into Arch linux.

Quoting: GuestFor me too Talos is slower with Vulkan: 49 FPS instead of 65 FPS in OpenGL.You've got a 660 just like Nel above, and he gets much better performance using Vulkan, with a slightly older beta driver from the same series. Does the Vulkan implementation use more video memory (and you've got less than him), or maybe your settings are different somehow? Oh, or maybe you're running the game from a slower drive and their new Vulkan backend doesn't do asset/shader loading/caching/compiling as efficiently as the OpenGL backend? I also assume you might not be running Debian Jessie with an older kernel like him. The possibilites are endless. :)
