Well, no games are slow or jerky, in fact, I can run MechWarrior 4 at 1024x768 w/32 bit color and EVERYTHING set to highest with no slowdown at all. I mean that it never gets jerky or anything, no distortion or anything else. I have no clue of the FPS, but I can tell that it is easily higher than 50 just from seeing various games running. Half-Life does not work under Win2k w/NTFS file system, so I cannot include that. Neither does Unreal Tournament want to install for some reason. I think I will wait for DNF and Unreal 2, along with AVP 2 and such and check then again. If it is not fixed, I will just get a SiS 735 or Nforce chipset based mainboard and avoid any problems with the Via686B and such.
I have DirectX 8.0 and the 12.41's, but I don't think it is a problem with either of those. These problems ALSO show up on a similiarly configured system, but with a GeForce2MX and an earlier driver set; scores of 1400 are WAY too low for a 1.4GHz Athlon, Asus A7M266, 512 DDR 2100 CL=2, and two 40GB in RAID setup, for speed.
