luxtorpeda VS Proton-Caller

There is also OpenGothic. Which can be used standalone or through Luxtorpeda.

Bit late but luxtorpeda has gzdoom as an option along with qzdl for launching with mods. You just gotta install protonup-qt from the discover store in desktop mode. A quick YouTube/Google search can show you how but that's the rough gist of it.

I use ProtonUp-Qt to get different Proton versions. You can find it there. You could also manually install Lux. Then just select it from the Compatibility tools.

try using Luxtorpeda to install ECWolf to play it instead

Released a new luxtorpeda-dev client (https://github.com/luxtorpeda-dev/luxtorpeda/releases/tag/v63)

There's a project called Luxtorpeda which acts as a compatibility layer in Steam but instead of running the game through Proton, it will download and run it with native engines and source ports. So if you enable it with classic Doom it will pop up with a dialog asking which port to play with (GZDoom, doomsday etc) and it will count towards your Steam play time, enable the Steam overlay etc. Keeps the engine up to date and works with lots of other games with open source ports too.

Since I couldn't get get with Proton 8 to work with Proton-Caller, I went with this standalone script:

Yeah pretty much. Check out Proton Caller: https://github.com/caverym/proton-caller

It's funny, I spent the time to get a windows app launching in proton as I was having some issues with the Linux version that I didn't have the time/patience to diagnose and fix myself.

The launcher is called proton-call ... I changed Steam to use the version of proton to match what the app expected, and it worked pretty cleanly. All said, I do wish it were easier for a separate launcher or third party to include proton as a separate package.

This tool can be installed through package manager in any Debian and Arch based distros. Also, it can be manually built and complied from source code. (here's the github link if you want to check it now: https://github.com/caverym/Proton-Caller/)

Run it through proton-caller instead of steam itself

As someone who owns a crap ton of games, Proton-GE works for every single game that are supposed to be working on Linux for me. I use it in conjunction with proton-caller, they just work. Not sure where this things are likely to break in subtle ways comes from.

Proton is not inseparably tied to Steam; you can easily run it outside that environment, and projects like proton-caller make it dead simple.

i use proton-caller and find it easier to manage non-steam games that way. heroic game launcher and bottles should be easier though.

Yes it is. But it's not recommended.
