My settings are not really preferencial.
I am sure these settings are more of performance/quality.

Filtering, Hi-res Textures, Dithering, the resolution and screen smoothing is something not seen on the original Playstation itself.

Your settings are optimised.

Really?
Maybe you should set everything to Quality in your nVidia Properties/ATI Catayst Centre.
