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: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.
