Hey guys, I was having issues with the gameplay and found a simple solution that helped me. My FPS was stuck at 30-40 no matter what I tried: lowering graphics settings to the minimum, updating NVidia drivers and restarted my computer multiple times. The moment I disabled full screen optimization, my FPS jumped to ~180. I think this is related to NVidia driver profiles not being able to be set on certain systems until you disable full screen optimization.
After reading Reddit posts, it seems like this fix can also help with Stuttering and being stuck at the loading screen.
I hope this helps!
