For those of you like me that cannot get Reshade to hook Pcsx2 (for GSDX11 graphic plugin only because it works 100% with GSDX9).
Here is a solution :
"Here's a workaround I came up with. Download it and run d3d11_fix_install.bat, and it should work. What this does is install a compatibility database telling Windows to force load "d3d11.dll" from the EXE's directory using the "InjectDLL" fix."
Rename your "dxgi.dll" to "d3d11.dll" and bam, it works
