I seem to have found some sort of graphics bug since upgrading my Geforce 5600 AGP to a 6600 AGP. All the frame rates seem to have improved and resolutions are higher, plus I can now run Oblivion. but I've got a weird bug in lots of my games. In Battle for Middle Earth 2, this shows itself as random black patches on textures during the game, and on Oblivion it causes random textures to appear in lines across the screen- there's a screenshot of it attached. Does anyone know how to fix it? Has anyone else noticed this problem? Any help at all is much appreciated! Some of my PC specs are on my profile, just ask if you have any questions. Thanks a lot!
