FPS Infinite has been updated to v1.17 and includes an engine update and fixes.
1) Fixed the endgame timer to display the time correctly, instead of just 0:00
2) Fixed the mouse rotating unexpectedly when clicking different buttons
3) Fixed particles not rendering on Linux (got rid of the noparticles argument)
4) Improved position updates from OpenVR to reduce latency
5) Updated MacOS libraries, although Mac is not well supported (since OSX doesn't support Vulkan and support through MoltenVK is experimental).
6) Updated to Focus Engine v3.18.8 (which has other minor fixes/performance improvements)
7) Includes NET 5 in Mac/Linux builds now as standalone runtime
v1.17.2 should fix a crash on launch (reported @ https://steamcommunity.com/app/1256380/discussions/0/1744520688775831493/?ctp=5#c3047230236576040148 )
Enjoy!
