There's a new version of NVidia's Forceware available (although I did not spot it from their own site), that fixes the bug of creature textures and shield textures getting goofed up when viewed from a close distance.
The version is 174.20, and I downloaded it from here: download from Guru3D.com
Choose the correct type of Nvidia Forceware (32-bit, 64-bit or Vista) and you get the installer after accepting their EULA. I myself have not had any bad experiences with that site
. I think they are pretty known amongst the manufacturers of drivers, since they seem to get the beta drivers and so on faster than they are put on the manufacturers' sites themselves.
Series of 6, 7, 8 and 9 geforces are supported with this driver release. Enjoy!
