This is what I use to get the true max quality out of my game. Note I also may force and/or enable a lil more also with my gpu's own settings software.
Install:
First run the latest installer for Reshade from Reshade.me
Upon launching it if it fails to detect or you dont want to sit around and wait for it to detect Forsaken Remastered's install then click the bottom right corner button, "Browse..."
Search for "selkis_x64.exe" in the games install location then click the "Next" button
Now reshade detects the game as using the "Vulkan" API but in reality by default its using the DX11 API...so select that option then click "Next"
On the "Select preset to install:" page just click "Next"
Then on the "Select effect packaged to install:" page make sure to CHECKMARK "Standard effects", "SweetFX by CeeJay.dk", & "qUINT by Marty McFly"
Then click "Next"
Then click "Finish"
After all that extract the contents of this rar to your game's install. Example: D:\GOG Games\Forsaken
ENJOY!
