The Talos Principle, Croteam's fantastic first-person puzzle game has a fresh beta available to test with some major changes.

It includes massive changes under the hood, including a much more up to date version of their Serious Engine. This brings with it 64bit by default, OpenGL removed in favour of Vulkan along with "various other optimizations, fixes, and tweaks that will make your gameplay experience better without you knowing why that is".

I did a few benchmarks this morning just to see how it's working now and unsurprisingly the Linux version remains incredibly smooth. With the performance options cranked to Ultra, rendering at 1080p and MSAA x4 on it was hitting an average of 112 FPS.

To access it, all you need to do is select the "publicbeta" branch on Steam. You can find it by right clicking the game in your Steam library, going to Properties and hit the Beta tab of the UI. From there, it's in the dropdown box:
