Shattered-Tale of the Forgotten King (Ubuntu 22.04 Gamescope-Lutris-GE-Proton7-16) [2160p] {6800XT}
Installed from Amazon games using Nile https://github.com/imLinguin/nile
Gamescope Setup Notes:
Next once the game is installed with Nile you want to add a new game to Lutris by clicking the + in the upper left hand corner and add locally installed game, then fill in all the appropriate info and browse to "ShatteredTOTFK.exe" in the root folder of where ever the game got installed and set that as the Executable on "Game Options" tab. Next Enable gamescope in game configuration on the System Options tab and set the appropriate resolutions in the output and game resolution fields for gamescope options right below the toggle on button. Scroll down a bit and switch the Mangohud toggle to off, turning this on here will break gamescope and for the final step to make Mangohud work scroll down on the System options tab to "Command prefix" box and put in just "mangohud" no quotes, then hit save and play the game!
