I recently got a new computer, which has 6 gigs of RAM and a dual core processor, which I was under the impression meant that it would be fast and I'd be able to play good games without lag or other problems. However, when I bought Unreal Tournament 3 I found that I had to put the graphics on the lowest setting so that the game would run at normal speed. Then today i tried the Arkham Asylum demo and found that it too ran very slowly, and I couldn't set the graphics to be any lower. Both games run on the Unreal Engine I noticed, might this have something to do with it? Combat Arms works very well on this computer, no lag, extremely fast loading and a high frame rate.
