I am running AMS2 using the F-USA cars and running full race distances. I have an ongoing issue that my screen starts stuttering when AI cars are making pit stops or have mechanical issues. I assume this is because there is a sudden need for processing power vs when all the cars are running as normal. When there are no pit stop I get consistent framerates of 95 + I've tried this with and without V-Synch but with no difference. I'm relatively new to PC gaming, so any ideas what is causing this and what I can change to stop it? My system details are: Processor: 11th Gen Intel(R) Core(TM) i9-11900K @ 3.50GHz 3.50 GHz RAM: 64GB GPU: RTX 3060 12MB
