Has anyone else had frame rate or graphics problems with Porto? This track seems to be the only one I'm having problems with. The Time Attack mode isn't too bad, but the frame rate is so low during a race event that it's basically unplayable. Also, when in the garage before starting a session the sky is black, like it was at night, and sometimes the icons for fuel, repairs, etc are missing. When exiting the garage it is daylight again, but some areas of the sky are black(a storm?). Wonder if I have some corrupted files or what... My setup is a 3.4 GHz Dell P4, 3 GB RAM & ATI X1950 Pro. Thanks.
