I want to make a 4k game video for Youtube but I only have access to a 1440p monitor. On Windows I could use DSR, how do I do this in Linux? Kubuntu, KDE Plasma 6.4.5, RTX 2080, Nvidia driver version 580.95.05

It works just fine for me. What are the steps that you did?

I use nix so:

  1. I installed OBS with all the plugins especially obs-vscapture
  2. Run OBS and add Game Capture Source
  3. Using lutris I enabled gamescope and changed the game resolution to something higher. I have a 1440p display so I tried 2560x1600 (16:10) to make sure I'm capturing it right.
  4. Inside Lutris System Options game options tab I added OBS_VKCAPTURE and set it to 1.
  5. When I run the game I can see gamescope is working as it's projecting a 16:10 game onto my 16:9 screen.
  6. Inside OBS I can see the game capture is working and when I select the Game Capture source it shows that it's a bit too tall for my display.

Should be a similar thing for you, I would try something obvious like 16:10 first so you can get immediate visual feedback and then tweak your settings from there.
