So did anybody ever figure out the problem with ut99 using nvidia's newer drivers?  I was able to solve my problem with my AGP 6800, by using an older driver.  I now have ditched that old AGP system, and went with a Pci-Xpress system, with a nvidia 6800gs card.  UT99 just freezes my movement sporadically and often, I go to move forward and the screen just blurs.  

I tried using the previous solution of reverting back to an older driver to no avail.  I can only use drivers going back to late last year, anything older and they don't support my card.  The one that I found before was from early or late 2004.  The only way to play without these hangups is to revert to software rendering, which  is even worse than 16-bit.

Any suggestions?
