Welppers I decided to test my system out, and install Doom III.
First of all let me say this, I have NEVER seen graphics like are in this game. Downright scary. One of the monsters made me pee pee. The gameplay, while buggy still(hey...its Alpha), is very playable. And oh the lighting....good lord man. Anyways on to the stuff. I deleted the doomcfg file, and let it rebuild. Changed the resolution to 1024x768, and ran it. The max framerate I saw was 63fps. That was running down a relatively dark hallway. The minimum I saw was 13fps. This was done with the rig in my sig. However I should note I did NOT have my vid card overclocked, nor my opengl setting tweaked. Im sure with some playing around, as well as installing the various patches, my fps would show a nice increase. This game is going to be a monster. :)
