Okay so I just booted the game, and immediately I noticed that the game was stuttering really really bad. I tried all different kinds of settings but nothing worked - until I remembered I had the same issue on a different game. The culprit? V-Sync. It could just be because I have an adaptive refresh rate, but I'm not sure.
So, I go into the resolution and change to 60 Hz from 240 Hz. It could be a simulation thing? If Unity is running different parts of the simulation based on the time between frames, then that might be the cause of the stuttering. Speaking of which, it would be helpful if you could find a way to list out the refresh rates alongside the resolution, or give an option to disable V-Sync.
