--- Comment #48 from hash HASH.DuOrden@gmail.com 2009-03-12 03:47:51 --- To Eli Wapniarski: You can "ask" you nvidia driver installed on you linux system for all "Option" parameter it can handle, with command: nvidia-settings -q all (this gonna be long list so I suggest add "|more" or something similar) And as I can see there is no parameter to disable S3TC for nvidia driver for Linux.
To brian willian: It look like you have something different with textures than this bug, most likely your PWI installation is corrupted in some way. With question mark, PW engine show absent textures.
