Just a few subtle changes .. trying to improve the game's graphics while still preserving the game's default colors and atmosphere.

This is a Reshade preset, I uploaded all the files needed just to make things easier.

This preset uses ambient occlusion, ambient light, bloom, dpx, liftgamagain, smaa and ca.
In the screenshots posted i also used SCAO from dsfix.
The ambient occlusion "bleeds" through fog, smoke or pre-rendered cutscenes, to disable/enable it press numpad 5, the ao render distance is low so it won't bleed through distant fog/smoke.
To disable the reshade preset press scroll lock.
I recommend playing the game at 30 fps while using this preset .. (i play at 40, with this preset my AMD 7950 can't do stable 60 fps)

To install just extract the files in the darksouls game folder.
