my brother showed me something wierd on his pc the other day, he was
playing q3 and the screen looked the same. i thought his card was overheating
but he figured out what had happened, was that he manually set his performance
settings to high quality. once he set it back to ‘let the application decide’
( which is default ) the wierd screen went away.
im not shure if that is your situation, but i thought i’d mention it since its kind
of wierd to see that same screen twice in a few days.
he runs a p4, nvidia 6600gt on xp.
