i had an amd athlon 1900 + geforce 2mx computer before, which ran dk1 at 60 fps but now i bought amd phenom 2 720 with radeon 4850 and my fps went down significantly. I am at a constant 16 fps for some reason. I tried "-fps 60" and it increased to a constant 40 but everything is faster so it's useless. The game is incredibly annoying and unsmooth at this low frame rate. Anyone knows what happened? I thought if you buy faster computers your fps is supposed to increase..
