I just upgraded my PIII 700 system to a P4 1.8GHz with 512 RDRAM. I'm using the ABIT TH7II mobo and a Gainward GeForce 3 64MB vid card on Windows ME. With the PIII system my 3D Mark 2001 score with this card was around 4500 at 1024x768x16. With my new system the score is 4250. I'm using the det4 21.85 drivers but have tried many different versions with the same results. I have tried everything I can think of to solve this problem including various changes to settings in the BIOS and different settings for the video card. FSAA is off, that was my initital thought what the problem was. I've also tried re-installing Windows with no luck. Please if you have any suggestions let me know cause this is really driving me nuts. I'm begining to think this might be a problem with the motherboard AGP bus or something. Please help!!!
