Pre update i was able to do AI races of about 40-50 cars around tracks and generally wouldn't get high fps drops, my settings were all ran on pretty much the lowest to be able to do this. But after the update (not sure if the update applies but its just when i most previously tried to do big grid races) I'll run lowest grahpics possible and as soon as i go to drive my car barely moves, frame rate plumits and the ai just glitch through me. Though when i turn on the AI driver the game just behaves fine the FPS returns. Any solutions? I previously tried doing a 17 car race in f2 and that ran just as bad
