Upscale on high resolution monitors on Linux with gamescope

Post by TheRealOptimusHippo »

This isn't a support request, I just wanted to share in case it helps others.

Linux has the gamescope program available from Valve Software https://github.com/ValveSoftware/gamescope. You can use it to upscale the game so you get to have nice big UI buttons and text without changing the resolution for the rest of your desktop environment.

I used:

Code: Select all

gamescope -w 1280 -h 720 -W 3840 -H 2160 -f -F fsr -- "/home/me/Games (Non-Steam)/Myth II/Myth2_64bit"
This runs Myth 2 at 1280x720 and then upscales it up to 3840x2160.

Code: Select all

-f
is for fullscreen

Code: Select all

-F fsr
is to use AMD's upscaler, which actually works really well!

There's a few other options available to you that are listed on the above Github link. (e.g. there's an Nvidia upscaler as well)

Thanks for sharing this, sounds handy. If you can post a screenshot of the fsr/nis option I'd be curious to see that as well (don't have access to it myself)

Sorry for the late reply. I don't know how to set my notification preferences well apparently 😂

The 4K images are bigger than the forum 4MB limit unfortunately but here's a comparison of a small part of screenshots with and without the upscaling (FSR).

The UI text and buttons are actually the same size with and without this upscaling. I think in my original post I may have been referring to the text and button size of the the main menu UI. The menu was giving me quite a headache reading it in 4K. The gamescope upscaler magically made that full screen and large too which is much nicer.

Below are the original 4K images:

The text is a bit clearer in the FSR version as well.
