I've been trying to work out why the Rockstar Social Club version of GTA V isn't working with Reshade 3.x.x. For those unaware, the Social Club Launcher stops repsonding very quickly after it launches when Reshade 3 is installed.
The Social Club version requires you run the "PlayGTAV.exe" file. This then loads the Social Club launcher application "GTAVLauncher.exe" which then eventually runs the "GTA5.exe" application (the game).
The dxgi.log that appears after the launcher crash starts with...
30/11/2016 22:49:40:735  | INFO | Initializing crosire's ReShade version '126.96.36.199' (64-bit) built on '2016-11-12 02:37:35' loaded from 'D:\Games\Rockstar Games\Grand Theft Auto V\dxgi.dll' to 'D:\Games\Rockstar Games\Grand Theft Auto V\GTAVLauncher.exe' ...
I wonder on Steam versions if Reshade is being loading to "GTAV.exe", whereas in the Social Club versions, you can see it's being loaded to "GTAVLauncher.exe".
@Crosire, does this help to solve this issue at all?
