I was messing around with Nvidia Inspector because I was bored and decided to force some Ambient Occlusion (since the ingame option seems to lower fps but do nothing at all)

It looks nice and adds a sense of depth I'd say especially with the shadows under the corpses and in that picture specifically that metal piece against the wall making it look nice.

This picture is a better example of seeing the shadows under the corpse where it looks nice, a good example would be if any of you played Skyrim with forced AO, it looks amazing.
It's not perfect yet as it flickers on and off most of the time so when I have it perfected if anyone wants I'll post how.

Also here I went into singleplayer and messed with some unreal commands (like turning up gamma and turning off post processing etc..) and in a weird way gamma turned up that high looks nice like if you look at the building at the top left, removed the hud and the weapons, squint your eyes it looks kind of realistic.
(squinting is an essential step as because this killed my eyes in game so the only thing I could do was squint so everything looks real

)
