you can try to enable Shaders though with ati cards its hit and miss.

some other options to try (in addition to the ones you used above)

Use vertex cache
Enable decoding of indexed textures (CLUT)
Enable dynamic shader generation

also try updating to a newer build (unless you had a typo 2763 is out :p )
