@Alex Hodgkinson I feel there's something wrong in physics, that is visible at 2:14, the R3E car is bouncing and become very unstable, I don't see that in this IRL video neither in others I checked. It's also the case at 7:02/7:10 section but less visible on the video. I used default setup.
I have seen many videos in this thread were people drive with 100 cars on track with brilliant graphics. What are your system specs?
