I have UT working fine on my system with no patches installed...so if you are having trouble this might help also Mechwarrior 3 works fine and Quake 2 and glQuake 1, but if you get an error message at the time of install like I did with mech3 just ignore it and the game will setup. However here is my setup...

Amd k6-2 380
64 meg ram
monster 3d voodoo2 8 meg
8meg s3 savage 3d
ga-5aa motherboard
win2k 2195

hope this is helpful to you

Are you running UT with openGL, D3D or something else?

ok that's all well but have you tried the patches from ut to fix some stuff did you have any problems afterwards???
