AMD VSR / NVIDIA DSR Alternative for Linux?

On windows when I had NVIDIA I used DSR to be able to select 1440p and 4k in game. Is there something similar where I can render games at higher resolutions and downscale to native? I have an AMD card rx 6700 xt and I'm using Sway (wayland).

Yup. Gamescope.

The command to force a certain resolution and frame rate would look like this:

gamescope -W 1920 -H 1080 -r 60 -- %command%

The resolution configured is the one the game will see, and the gamescope window can then be resized or full screened as you like.

It can also run games at lower resolutions, and upscale them using FSR. 1080>4K looks like this:

gamescope -w 1920 -h 1080 -W 3840 -H 2160 -F fsr -- %command%
- The -F fsr didn't work for me, but the resolutions that are between 1080 and 1440, and 1440 and 2160 are fsr upscaled from what I understand, so that worked for me.
- Your link doesn't work for me on Jerboa.
  
  Ok. What do you want me to do about it?
  
  You can view the URL using "view source" and you'll also be able to see there's no error in the formatting that would break the link, so this is entirely up to jerboa/your device.
  
  That's for Jerboa to fix. It's valid markdown.
Gamescope can do this
Thanks for recommending gamescope. I was trying so hard but it wasn't working, turns out it was because I was using the flatpak version of steam and gamescope. When I installed the fedora steam (rpm-fusion) and gamescope, it worked without any issue.

I know that it is possible to run gamescope on flatpak steam, but it didn't work for me.

4k FSR boosted my fps from 60 to 100 and it maybe looks even better, it blew my mind.
