I have the latest drivers and the latest directx. The graphics card aren't locked to a very high AA setting. I have no viruses and no spyware. Also my WindowsXP is new. There is no reason to reformat. I noticed that when I switch to 32bit the game is slow -> 5-10fps (I mean...not like 16bit -> 33fps for sure!) also with low lighting. I tried the "fastest" option and it switch to 16 bit without lightning. The same thing is with "Hammer and Sickle"...maybe a little better... I begin to think that the problem is the game engine...
