Ah but your problem is different,I am using a Raedon 9800 pro now
All my Geforces (lol) and this Raedon I also need to increase my gamma a tad for my games to be bright enough (like you said but mines about 1.30)
Your saying your game is fine as long as you increase the gamma but your screenshots are almost black?
The way I save a screenshot,is printscreen and then I alt-tab out and open Paintshop Pro (6 I think) and paste the clipboard and they are always a little too dark (what my game is without the gamma increase actually) and I adjust the brightness and contrast of every pic. But they are not real dark like you are saying.I suspect what program you are using to paste your screenshots?
My problem I was having in this topic was different,reading back I didn't explain well but I know now my problem was:
1. My Resistance was stuck at 12 midnight is my guess.
Running non Resistance (1.20) was fine and it must have been something within my Resistnace config files.
I could use the editor and make it any time I wanted,but it always was 12 midnight (i was able to turn on lights and such).
Every single player mission I played was also at 12 midnight
Which leaves csla mod as suspect ,as I reinstalled (back to 1.96) and everything has been fine
