I had this problem once before and I remember it was fixed by editing one of the config files but its been a long time now so I have forgotten what the fix was. The right side will looks perfect while the left has a slight pixelation. My system is Amd Phenom 9850 BE Biostar TA790GX3 ATI Radeon 4850 1GB in crossfire and ASUS physx card my screen is a plasma Samsung 50 inch HDTV @1920 X 1080 resolution. Regardless of which resolution or plugin I use it always appears the same. For some reason I think it was projection hack that fixed it but I really am not sure and don't remember.
Thanks for your help with this
