StixsworldHD's HD-4K Experience
From his project site:
With his mod:This mod/preset is designed to help you get the sharpest, cleanest image you may get out of your game without the need to force anything upon your gpu and taken a massive performance hit.
I spent many years injecting shaders into games and for the longest time I was like everyone else and always skrewing over the lighting and actually making the overall image blurrier than it by default was. This the final product of solving those issues.
