I defragged my drive right after I installed the game (probably should have right before I think, but whatevah).tedtropy said:One thing that may or may not help some is simply defragmenting the partition that you have Doom 3 installed on. The install for the game dumps quite a bit of non-continious data on your hard drive. There's also cache settings within the game's config file that you can screw around with that may help, though personally I didn't get any real results out of that.
I'll try dropping the quality setting down a notch. Would it help to have more ram? Or more video ram?
