For some reason I get very bad stutter after joining the game. FPS doesn't really exceed 40 and I get massive FPS drops. After 10 seconds of waiting framerate climbs up to 100-140 where it should be at ultra settings but I still get some minor hiccups for a while but eventually they also disappear and game runs smooth. DX12 is unplayable and DX11 works much better but stutter is still there.
Any ideas? I haven't played for a while so maybe some recent update broke the game. I deleted the game and installed it on a fast NVME SSD but it didn't really help at all. Temperatures are fine, I don't have similar issues with other games and both CPU and GPU usage are low during FPS drops.
