I recently reformatted/reloaded a older (K62/450) computer running 98 SE for the kids. After I was done and ran Half-Life, the performance was horrible. I figured the old Monster II had finally bit the dust (one of the reasons why I was reloading the machine was because 3D performance in anything, even MAME, was terrible), so I picked up a MX400 PCI card (no AGP slots). Running 12.41 Detonators, the performance was still awful. Upgraded drivers to 21.83 and it was even worse! I couldn't understand it - this computer had always run HL fine, not in high resolution, but 800x600 worked fine. And the MX400 had to be faster than the Monster II.
Then it hit me...
When I reformatted/reloaded, it disabled DMA drive access. Once I re-enabled it, things are back to working very well.
Just a suggestion for those that might be running into similar problems.
One question, though...is DMA access automatically enabled in XP? I don't see where I can enable it, so I assume it is.
