I typically run at 1280x1024 4xAA in DOOM3 and get a steady 60fps, and 30+ when there is mass action. But for some reason, my Geforce 6800GT can't handle simple smoke algorithms?
I drop to 20FPS and gameplay gets really choppy. Even if I turn off 4xAA, I still get a massive drop when smoke shows in DOOM3.
Is this indicative of the GeForce series, or am I doing something wrong? I am currently using the 66.31 which definitely showed improvement in DOOM3 for me anyways...
Thanks in advance for any help.
