I got an x64 AMD X2 4400+ with 2GB ram and a 6800LE gfx card, why am i getting lag even when everything in the game and windows is turned to VERY LOW/DISABLED, and windows to "High performance" ? I cant seem to stop the visual lag when in hevily wooded areas, or areas where more then 2 objects are on fire with smoke. Surely my graphics are not that bad that this should happen.. If i can play Doom 3, im sure i should be able to play this.... Please advise
