GeFroce3+Det4+WinXP=wierd UT problem, please help

[DragonFire]

Now that the DET4 drivers are out, I thought I would give ut a try and wouldnt you know it, im having problems.......GRRR


The max full screen res that I can get is 1024x786x32.........any res higher then that and UT goes in a window or if I do get it full screen, its using software mode. Picture 1280x1024x32 at 10fps.......ewwww



I have a GeForce3
AMD TB at 1533MHz
786 megs of ram...
using the Windows XP RC2
using the lastest opengl driver
using the lastest UT patch


Any ideas how I can get 280x1024x32 using hardware full screen?
