I'm having this problem since version 1.03 of the PC game (it's the first one I've played since I bought the game). Now I play the 1.10 version.
When I launch the game with steam, the intro (the one with the lights that turn on and then when he asks me to press the options button) have a very annoying lag. this happens even during the loading of the tracks, both in time trial and when I make a GP.
I have a video demonstration of the problem and the info file DxDiag. Let me know as soon as possible thanks!
