Hmmm tried now.. several different options.
Compressed textures, no compressed textures, low rez and high rez.. no AA and 2xAA, Level of detail to see polycount effect in various settings, Mirrors on off, mirror detail higher/lower.. guess what.. perfectly same FPS with every setting.. so i was right.. its rather my AMD Athlon 64 3200+ failing than Geforce 7600gt.
Any way to reduce stress on processor in the game? And dont tell me about windows tweaks, im well enlightened with those.
EDIT:Fixed typos... damn Africans.. making too good Shiraz takes the sharpness out the man!
