ReShade's installer is just a weird .zip file and GShade is just reskinned ReShade with barely any new features. Almost every single shader I've tested works fine on ReShade.
GShade's shaders are available on a GitHub repository, so you can just yoink them with this nice little tool, no hassle required.
## Help, something's broken
If it's with the installer - email me! `geezshade@(my username).com`
If it's with ReShade or the shaders - don't waste your time. GShade provides no guarantees their shaders will work on ReShade.
