[help] Ferrari 458 problem

[Alberto Zanot]

Hi! I'm playing the career and in a race with the Ferrari 458 at SPA i see a huge framedrop, expecially in the track part right after the first steep right turn, the long descent, then up, and then in the forest. In the forest my FPS goes from 60 to 45.
What i don't understand, is that in career there is another race, on the same SPA track, same weather, but with the Mercedes SLS, and i do not have frame drops.

F 458 bugged?!
