TY for your hard work!Can you post your PC specs and are you on windows 10/11?
I just updated the project to unity 2022 from 2021 and recompiled all shaders, some are even brand new, so hopefully that can fix it for you. I can send you a test in a few days.
Specs are 2.9 Ghz Intel i5-9400F, 32 G RAM, Geforce GTX 750 Ti (2 G) for PC and 2.9 Ghz AMD Ryzen 5 4600H, 8 G RAM, NVIDIA GeForce GTX 1660 Ti (6 G) for laptop (tried on both). Win 10 on PC, Win 11 on laptop. All drivers were updated when I tried to play.
