Nothing you have set globally makes sense:
Ansiotropic Filtering is on, but very low.
FSAA Gamma Correction is on, but FSAA is off.
FSAA Transparency is on, but FSAA is off.
All speed optimizations are on.
These settings will provide you with an image quality of 2 on a scale of 1-10.
If your intention was to speed up a slow game, I hope it helped.
