Just FYI, GOG Galaxy and GOG games mess with in-game overlay and other type of rendering, which prevents many GOG Games, such as Grim Dawn and Dying Light - The Following (Enhanced Edition) from working with ReShade 2.0 (2.0.3f1 or any newer). As long as GOG Galaxy is installed, even GOG Games which were installed separately using full installers, stop working with ReShade 2.0. It is NOT ReShade's fault, but GOG Galaxy's. Only upon full remove of GOG Galaxy GOG Games begin working with ReShade 2.0.

GOG Galaxy often uses the worst naming of their overlay renderers, giving them the exact names ReShade DLL's must use, such as DXGI and D3D11. Removing vanilla DXGI and D3D11 doesn't prevent games from working, but removing does not solve the problem of GOG Games not working with ReShade 2.0 (or newer) while GOG Galaxy is installed.

They name their overlay D3D11?

I question the accuracy of this. Please provide some details, such as how you arrived at this conclusion. I'm not seeing anything in Galaxy or any GOG game I have (granted, I haven't checked them all) indicating its GOG using naming conventions like that.

EDIT - 96 games + Galaxy checked and not a single instance of DXGI.dll or D3D11.dll found in any game or Galaxy directory

Dying Light - The Following (Enhanced Edition) included both D3D11 and DXGI DLL files, but GOG Galaxy was installed and it detected and was linked to the game. When installed through GOG Galaxy, Witcher 3 also had DXGI DLL file (for GOG), not from ReShade. Look through the latest D3D11 titles, preferable 64bit.

The naming of the files is not the problem because GOG D3D11 and GOG DXGI DLL files can be removed and the game will still work. I think the problem is that when GOG Galaxy is installed, GOG-related DLL files in game directories, such as Galaxy.dll and/or Galaxy64.dll active GOG Galaxy services and then the game will not work if ReShade is installed. There's a whole discussion about it on ReShade forums.

Well, that explains that, I don't have any of those games. I suspect it is Galaxy's auto updating that is the problem. ReShade replaces the GOG DLLs, Galaxy updates them back to the originals. That's just a suspicion though. You could try turning off Galaxy's update feature for that game to see if it helps.
