OK, I've just bought Kane and Lynch and after getting past that 'R6025 pure virtual function call' error (a convoluted System Restore/Re-install solution), I now have a more irritating glitch:

As you can see: invisible textures. Very annoying.

Here's my system specifications:

Windows Vista Ultimate 64bit
Intel Core 2 Quad Core 2.4Ghz
GeForce 9800 GTX 1GB DDR3 VRAM

As far as I know, all the drivers are up to date.

Cheers in advance.
