This mod is an installation script for Artur's DLSS Enabler which itself is a combination of multiple other projects.
Run this command in the terminal
curl https://raw.githubusercontent.com/FakeMichau/fgmod/main/prepare.sh | bash --This will create a folder called fgmod in your home directory with a wrapper fgmod inside of it.
Before running it, at least take a look at prepare.sh and fgmod.sh, piping stuff blindly into sh is not wise.
After running the script, you will be given the exact command. In case you missed it, look below.
For Steam, add this to the launch options /home/USERNAME/fgmod/fgmod %COMMAND%
For Heroic, add this as a new wrapper /home/USERNAME/fgmod/fgmod
Just replace USERNAME with your own.
There is PKGBUILD, download that and fgmod.sh, you know what to do with it - makepkg. Usage is simpler, just add fgmod as a wrapper.
/home/USERNAME/fgmod/fgmod from the launch optionsfgmod-uninstaller.sh found in the game folder, it will not always be the main folder/home/USERNAME/fgmod folder
