I'm having trouble with corrupted 3D graphics in games. The 2D seems to all appear fine, however, the textures in certain spots of models are completely transparent. They seem to flash in and out rapidly. Some games are worse than others. Company of Heroes has minimal corruption, while Neverwinter Nights 2 is practically unplayable.
Here is an example:
I would really like to upgrade to a PCI Express mobo and an SLI video card, but I'm not quite ready to make that kind of investment. I'm hoping that this is a graphics card issue and not something else. I would like to replace the graphics card (hopefully fixing the corruption) for now until I am ready to build a new PC. Any comments/suggestions?
