I have the same problem. I don't know if its my graphic cards, or the CRT moniters I have but it seems almost every game that is somewhat dark, its VERY DARK on my computer. I have the brightness on my moniter (ViewSonic A72f) to the max and I have the brightness for my Nvidia Gefore FX 5200 as high as I want to set it. If it wasnt for those settings even games that have shadowing would be almost unplayable. Every game that has a gamma setting I have to increse that to the max to make the games look somewhat normal. If I ajust my video cards brightness any higher my start bar on windows will be glowing white and ugly
To bad SH3 dosent have a gamma setting...
