So a couple weeks ago i found a program called "ReShade" and i installed it with pluto and began messing with some different options (Plz keep in mind that this program doesn't edit the actual games textures in any way but instead throws filters on the game to change how things look)
After image on nuketown (Forgot to grab a before image at the time)
before and after on turbine
(Note: This kills your fps as i usually run bo2 at 150+ fps and with this i was dropping down to as low as 50 fps) (Edit: If anyone would like to contact me my discord is Zolar#8160)
