What kind of graphics cards work well with UT?
Any card built with the capacity for 3D acceleration is ideally the best card to use. The engine in UT was designed with the voodoo line of cards in mind, so you get less hassle using that particular card with the GLide drivers in mind. I use the Matrox G400 max and D3D drivers with no trouble, but many members of the newsgroup have reported difficulties with that set-up. The Nvidia/GeForce cards are potentially the most powerful cards on the market to date, but UT and the 4.05b patch still offer very little support for them.
