This article on the repo is also an interesting read:

Porting LSFG to native Vulkan

Lossless Scaling is a very popular application for Windows

This has never been true and writing it in an article as if it were true doesn't make it more true.

Here's the installation instructions, although the build instructions are not going to work on Steam Deck by default due to it's locked file system. I'll probably try it on my desktop later and see if I can get it to work.

Ideally I think this project could later be installed through a decky plugin, similar to decky framegen.

Edit: It's weird, running it on my desktop it keeps giving an error about failing to create a pipeline. Running it with sudo privileges doesn't give the error, but seemingly doesn't do anything. I don't really have any experience with graphics so I'm not sure what's going wrong.

Lossless scaling worked wonders for me on windows before I upgrades to a 4080.

I only game Linux now, so I hope this becomes an option

Nice, will need to try this out when I have a sec.
