Not a big fan of the bloom effect in that game. If it were me (i.e. if my computer had a hope in hell of playing that game), I'd turn on everything except the bloom.
Nah the game doesn't have overly strong HDr (Crysis doesn't do bloom), it is just that this custom map had already high settigns and with my HDRLevel set to 1.6 it just got far more than what the creator intended. They still look incredible nonethless.
So r_HDRLevel from default 0.6 to X where X is what you like. r_HDRBrightOffset to make it less powerful and less colorful.
Obviously my settings where for the default game which can be seen in my sig (my Crysis cryboy ( ) ss. And also it depends on how strong the sun is shining and eye adation state.
BTW you want a small ss set with different HDRLevel settings of same map?
