This ReShade uses various shaders that improve colours, bloom, sharpening, texture detail. 

Note-the intended look requires Permanent Partial PostProcess Removal to be installed

-MagicHDR shader used make Gotham look darker yet more vibrant and contrasted

-Colour Temperature shader used to make light illumination more warm

-Cinematic LUT shader used to correct colours

-Colorfulness shader used for making lights and bloom pop out more 

-Adaptive sharpen shader used for giving the image more clarity and detail (more noticable on lower res screens like 1080p)

-DELC sharpen shader used for giving textures more clarity and detail

All these shaders are artifact free so there should not be any visual weirdness or bugs 

its very lightweight ReShade too, barely affected my FPS id say 2-5% decrease in FPS depending on your PC specs
