The Nurburgring is bugged. When I exit to the monitor the frame rate is horrible in the playback. When I exit back to the track, its stays at that really bad frame rate. Also, when I start a race, the frames are around 55-60 (100 less than any other track). I'll purposely hang back and when I hit the straight again, it will be running at 100+fps with all the cars, garage, etc. visible, unless I exit to the monitor and come back in, then it goes to like 30 fps. There's a bug for sure. My quick spec, i9, rtx 2080 latest drivers.
