After losing a hard disk I recently had to reinstall Win2k. All went well, or so it seemed. I was using the 3.81 Detonators previously and everything was okay. After the reinstall I used the 3.81 drivers, but if I tried to change resolutions in any openGL program (from the default 640x480) the program would crash. I removed (thoroughly) and reinstalled all the drivers I could find for W2k, but I got the same problem with each of them. This is until I tried the 5.13 drivers. The 5.13 drivers seemed to work beautifully. Everything seemed to work even better than before. However, thats before I reinstalled Q3A. Although other OpenGL programs run fine, Quake III runs at a less than stellar 1/2 a frame per second. It is seriously that bad, and I can't figure out why it is soooo unbearably slow. I then noticed Half Life had the same problem and so did my OpenGl screensavers (which are slow and have a strange colored bar hanging off to the side). I originally thought it was Quake engine games only, but SOF runs just fine. I really can't find any solution, I've tried almost everything, anyone have any ideas? This is really ticking me off.. I would go back to the earlier drivers but they just crash my programs. I had it working on a previous W2K setup, so I know there must be something I'm missing.
 
BTW, I'm running a Creative TNT2
