I am wondering if anyone else has this issue (I am sure I am not unique). I can run twenty two FB cars at Mills and I am getting 45fps at the back of the grid at the start of a race. By the second corner the fps is up to 75-80. Which is great and very playable. Here's my problem. When I run the 60's mod at Spa if I run 12 cars I get 30fps at the back of the grid. By mid way thru a lap it is up to 50+ fps. If I add just one more car to the grid the frame rate drops to 1 and the game stops responding. This does not happen with the Meganes or the new GT cars. Does anyone have any suggestions (other than don't run more than 12 cars)?
I just tried Spa with 19 AI in the 60s mod, and at the start I was getting about 56 FPS at the back of the grid, with visibility set to 8 cars in game, then after the field ran off and left me, I was around 100 MOST of the time.
