I has this a couple of times now where I would starts a race (20 Ai) and my FPS would be below 60 and would remain low for the race. However if I restart the race (Esc / restart - so in the same place on the grid) then my FPS are back at 60 both on the grid and during the race
This happens every time when I have environmental mapping set to yes (also have FXAA on and AA @ level 3) Test case Mills with the F3 1st race with 20 AI FPS is 49 at the start. after running down the S/F straight and then restart (esc / restart) I get 60 FPS again
Still getting this with the 295.73 Nvidia drivers I have vsync forced in the drivers and not set ingame (seems to give the best stutter free solution for my rig) But every time I run the practice session then go into race I lose 10 FPS (ie its at 50 FPS) Then drive down the straight and restart and its back at 60 FPS (and smooth). any subsequent restarts are at 60 FPS Only happens when I have environment reflections on - but this maybe because the min FPS get gets closer to 60
