I installed everything, updated everything but in certain parts of each map I play on, the textures from the outside of the map are showing up through the walls.. i dont know if i did something wrong but it kind of goes away if i enter certain parts of the map and then comes back at certain parts.. im using MBP with 2gig ram and radeonx1600 gfx.. im not sure if there is a way to update what i have if i need to.. anyone else have this problem?
