Texture glitches.

The problem is that when using Windows 7 x64 or Windows Vista x64 with Nvidia video cards, the textures are displayed incorrectly (they smear across the screen). This problem occurs for many users with this configuration, but no one can provide an answer. I have tried everything I could, tried different compatibility settings – it’s useless. I configured the drivers manually, but that didn’t yield any results either. I killed processes, except for the main system processes – the result is 0. When using x86 versions of these operating systems, this problem does not exist. Also, it doesn’t occur when using ATI (AMD) video cards on x64 versions of the same operating systems. Therefore, the Nvidia driver is to blame. IF ANYONE KNOWS THE SOLUTION TO THIS PROBLEM, PLEASE WRITE WHAT TO DO. IF YOU DON’T KNOW, DON’T WRITE THINGS LIKE “IT WORKS FOR ME.”
