Another guy figured out how to adjust the gamma to brighten up doom 3 simply open up your ingame control by pressing your ` button and type r_gamma x x can be 1 -3. Well 1 is the default setting... I adjusted to 3 and its way to bright, then I adjusted it to 2 and was still tad to bright so was like dam. Well I thought hey maybe you can adjust it like 1.2 or 1.5or 1.7 etc and you can! Im telling ya set your gamma to 1.3 and its freakin perfect not to bright not to dark just makes the game come alive and look kick ass. If ne1 has the game could you please put up some screens with gamma at default and then gamma at 1.3 also to compare. youll love it ! 1.5 looks dam good also
