I tried 1nsane, I've included both screenshots.

The menu doesn't scale, you need to go in game to see it.  And even then, you might have to zoom in to 400% or so to see the actual difference on my screenshots. (2k native vs 4k downscaled to 2k).

Lutris settings:

With gamescope you're only defining a virtual screen space for the game to render in. It's down to the game/dgvoodoo to be able to render at the higher resolution that gamescope is telling the game is available.

Native 2K

4K Downscaled

______________________________

For GLXGears you also need to tell it to render in fullscreen so it uses all the available resolution that gamescope is allowing it to.
 

gamescope -w 7680 -h 4320 -W 3840 -H 2160 -- glxgears -fullscreen
