Since Simbin installed the new patch the race series is as slow as crap on my system. Stutters as many no one likes. In the past I've given setups in the ATi screen that helped numerous of people, but I can't solve it now. I'm using an HD4850 and I'm running maxed out, 8xAA, 16xAF and 1920*1080 on 22" monitor. I also do not want to lower this as I'm used to these settings.. So I'm focusing on ATi drivers now, and have tried 9.6, 9.9 and 9.10 all of them didn't solve it.. I think it's a problem with the latest patch... But if someone has it running smoothly, please tell me how... OT: The offline pre-release version of Race On worked sooo smooth.. //edit tried around and so, and it seems it's mainly Curitiba causing a problem. All other tracks are doing fine..
