If you are having missing textures and problems, just download Quick_Install.zip and drop the two folders (Shaders & Textures) into reshade-shaders folder, and drop the preset into a place where you can load it up. This folder doesn't have any customisation and is used to quickly resolve any texture problems reshade might have with manual installation.

Note: If you have weird grainy, filmic effect on startup, it is due to two duplicate Technicolour.fx so just uncheck one of them & if it doesnt fix it, then re-enable it and disable the other. Then right click on the duplicate fx and click "Open Folder in Explorer". Then delete the fx from the Reshade - Shaders file.
If the preset is too dark you can enable CShade_ColourBlendOp or edit Gamma in RA_ImageAdjustment
