--- Comment #5 from Tobias Jakobi liquid.acid@gmx.net 2008-08-02 10:52:22 --- Sorry, I first thought that adding the FX series to the second fixup in fixup_extensions (directx.c, around line 3688 in current git) would be enough.
But after reading the comment there it doesn't seem to be a correct fix. According to the comment on OpenGL.org the driver falls back to software as soon as ARB_texture_npot is used, even if we're staying inside the limitations of the tex_rect extension. So we need a different fixup here that just removes ARB_tex_npot from the supported list of extensions. Something that does the same like removing the ext from the array in directx.c...
