OK, so the issue with texture quality getting stuck on low is actually a problem with Eyefinity+Crossfire. It works fine if I use just Crossfire or just Eyefinity, but when both are enabled, texture quality defaults to the laughably bad low or very low setting and can't be increased. It's so bad, you can't read the opening quote, see Booker's name on the wooden box you're handed in the opening scene, or see any of the photos/notes in the box. They're all a blurry mess.
Hopefully AMD will release a Crossfire profile or driver update to fix it soon, 'cause there's no way I can push ultra settings at 6048x1080 with just one 7950.
*Edit: I'm currently running 13.3 beta drivers with 12.11 CAP 2.
I've posted about the issue on the
2K support forums, chime in and let them know if you run into it too.
Here are some screenshots to demonstrate:
You should be seeing the game's opening quote here:
Booker's name is supposed to be engraved on this box:
