Turn up the gamma on your monitor? Honestly that image looks perfectly fine to me.s15.postimg.org/gd8pv47kb/fallout2_HR_2016_01_02_17_02_47_832

The blacks just look unnatural, and this is the only game whose blacks look so bad for me.
I don't have a gamma setting on my Asus monitor but for my brightness it's set at 50/100
I'm using the hi-res patch's 32-bit mode since sfall's 32-bit mode made performance really bad. I guess I'll just deal with it being so dark.
