Yes, SweetFx is a powerful tool. Good tutorials on YouTube on how to use and set up. Look for the videos by "Adipose". He shows what this tool can do by using Border Lands and Batman as examples. You could tweak just about every graphic option you could think of. A word of advice. Turn off any in game FXAA options. In SH4, turn off the Post Process Filters. By using the SweetFx hotkey (forgot what it is) you could turn it on or off at will in game, and see the difference. Also, as far as I know, the tool only works for DX based games, not Open GL. Give it a try, you won't be disappointed!
