Does this commit fix the issue?

I tested the patch with Red Alert 3 Demo, and it fixes the issue for me (black screen). Demo does not expose the DXTn textures issue in the tutorial at least, though it must be still there (it is staged). I suppose this bug is resolved now (there are separate open bugs related to DXTn textures).
