Aha! That did it, man! I was actually trying this method earlier, but I forgot that I need "wine" in there since it was a .exe file.

Trying to run "Star Wars: Knights of the Old Republic" (NOT the online MMO -- rather, the single-player RPG).
Upon running the .exe, the "splash screen credits" (LucasArts, BioWare, etc.) ran fine, but the menu had a white background and all 3D models were lacking textures of any kind. Additionally, many text objects appeared as blobs or blocks instead of letters.
After the help of this forum, it was discovered that S3TC texture compression was disabled by default for me. DRIConf ("3D Acceleration") did not present this option to me. Somehow I must enable S3TC texture compression.
When running the .exe, use the command line tool "force_s3tc_enable=true" BEFORE the rest of the NORMAL command to run the file. In my case, the following is run:
force_s3tc_enable=true wine /home/robert/.wine/drive_c/Program\ Files/LucasArts/SWKotOR/swkotor.exe
-Using the latest game version (1.0.3)
-No custom registry keys have been added.
-WINE is configured to run in Windowed mode, so none the of "disable certain mouse settings" apply.
-As far as game configuration goes, the default game settings appear to work just fine.
-The game disc is Disc 1 and is mounted manually from an .iso for the sake of a speed increase. This should be no different than from a physical CD/DVD, though.
