This preset was meant to make the game darker, sharper, and more horrific. I used max in-game settings with Chromatic Aberration set to "off", Anti-Aliasing set to "TAA", Ambient Occlusion set to "HBAO+". Adjust brightness and color space according to your tastes.
To install just extract the files to your RE7 directory. The mediafire link is in the preset text file that you download from this page.
