Same here. I have tried everything that doesn’t involve changing Windows settings (not going to mess with the thread director or core unparking), but have given up for now. The only thing that made a noticeable difference was changing my RAM timings and speed to be slightly slower, and limiting the fps to 144.
Game still crashes randomly, usually when restarting or loading a level, and the stutters are very random but consistent in the big Syria cities with low flight. I think there’s a compounding issue with memory management and thread usage, it doesn’t feel like one issue.
