hmmmm. this game is strange, or else my computer is strange. have just reinstalled windows blah blah blah. have all the latest drivers, and everything is clean and nice. i power up doom 3, put settings to medium on 800 by 600 res, start a new game, opens up the console and writes that thing that makes me see how many fps i´m running at, notice i´m running at about 30-40 fps... BUT THE GAME IS FREAKING UNPLAYABLE!
turn that smooth mouse thing up halfways in the options, and add a hell of a lot of stuttering, and you have my play experience...
and when i think about it it has been like this in farcry also. and i just thought that that game was supposed to be half-stuttering... now this is driving me mad.
edit: after playing some more i can say that i honestly cant see any difference between playing at LOW settings 640x480 or HIGH settings 800x600... both runs at ****... even at low settings, while turning off everything under "advanced" the game stutters like mad... i´m beginning to feel my gpu might not be as it should be.
