First of all, sorry for my english. I have an error in Spa66 when it rain. I don't know in the others tracks. The trees revolve as if it were a tornado. They move when I accelerate. If I stop, the trees also stop. I only play online, and on the dedicated server, my community uses "random time" I play at 1440x900 (max) in Windows7 64bit In game everything at max, except shadows (medium/quality) and special effects to minimum. The rest at max. My computer is a: Processor: AMD FX 8350 @ 4Ghz, 8 cores. RAM: GSkill Ripjaws 8GB @ 1600Mhz CL9 Motherboard: Asus M5A99FX Pro R2.0 Graphic card: ATI HD 5770 1GB GDDR5 (Driver 13.4) As I can not explain properly, because I only speak Spanish and French, I leave a video of the bug.
