This may be more of a mod issue then a track issue, but in some cases I am see a huge stutter or a jitter movement from the AI cars when I am next to them. I see it in both my mirrors and when the cars are in front of me for several yards ahead. I've seen it with ISI Indycar, and Formula E on Indy and Lester respectively. I then went to the KartSim mod and also loaded up with one of their tracks with a couple dozen AI and it doesn't happen there. Matter of fact rf2 runs quite smoothly. Has anybody else seen this? My settings haven't changed in a couple of years, and it seems to have cropped up in the last few months.
