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.
Sounds like your system might be struggling to keep up with some content (CPU especially), but there is currently testing going on to try and reduce this: https://forum.studio-397.com/index....f-realtime-physics-freezes-public-test.62687/
