I have a CTX AMD K6 300MHz with 128MB and a Riva TNT 16MB. I am having problems with walls and paths disappearing when I am playing UT. At this point I am running with the 3d drivers with low settings for both skins and textures. Also 16 bit and a resolution of 600x400 but things are still very sketchy. I am falling into a lot of lava because paths just disappear and running into alot of walls because they are not completely rendered. Is there anything else I can do ?
