I have an Athlon 1600 with Gainward Ti200 @ 220/500. On Win Me (detonator 22.80) I used to get over 7400 points. Today I reformatted the disk and installed XP and det 27.10 - 3DMark went down to 7204. I don't know what to do. I tried installing via 4in1 and it didn't help (doing it on ME was a big improvement in frame rates). Any ideas???
