GModCEFCodecFix VS ProtonUp-Qt

Next: Download the “GModCEFCodexFix-macOS” from here https://github.com/solsticegamestudios/GModCEFCodecFix

There’s apatcher for it. Gets the game running generally as it should (although I find performance is lackluster, but I don’t think that’s the patcher’s fault.)

https://github.com/solsticegamestudios/GModCEFCodecFix/releases its the link

If you're using the x86_64 version (which you should be), this tool should fix your issues: https://github.com/solsticegamestudios/GModCEFCodecFix

You can already play Gmod natively. Select the 64 bit test branch and use this: https://github.com/solsticegamestudios/GModCEFCodecFix

If you already habe the 64bit branch, then you can try the Gmod CEF Codec Fix. https://github.com/solsticegamestudios/GModCEFCodecFix/releases/tag/20221219 Download the file for your OS and run it

Instead of using the replacement lua menu, I’d recommend you to use the CEF-codec fix, as it is a much better solution: https://github.com/solsticegamestudios/GModCEFCodecFix

Use this to fix gmod https://github.com/solsticegamestudios/GModCEFCodecFix

No, I just use net_graph 2. Also for the 64-bit version not working, use GModCEFCodecFix, you need it for the 64-bit version to work

-Maybe audio some codecs are missing. Try installing some from the arch wiki or apply this fix :https://github.com/solsticegamestudios/GModCEFCodecFix (helped me prevent crashes.)

Lutris is a launcher for applications that run on Linux, that's the most comprehensive answer. It is highly configurable and supports scripting. Probably the most common use is launching non-steam Windows games with Wine and DXVK/VKD3D (I recommend a tool called ProtonUp-Qt for managing versions of this software). However, it can be configured to launch just about anything, including native Linux executables etc. Many popular titles will have scripts that automate the installation and setup, making them plug and play (if the script is good, that is). But everything the script does can be done manually too.

Try Installing proton up qt (haven’t tried it yet, I have the same issues as you). You can find it here (use dxvk): https://davidotek.github.io/protonup-qt/

Easiest way is to ise ProtonUp-Qt: https://github.com/DavidoTek/ProtonUp-Qt

Install ProtonUp-Qt from the Discover store and open it

/// protonGE downloader ensures you have the latest version

In the discover store you can find https://davidotek.github.io/protonup-qt/ that will download the latest.

Try installing it through Steam instead of using Wine directly. Mine is currently set to "Force the use of a specific Steam Play compatibility tool" and GE-Proton7-41, so try installing that one if none of the Proton versions that come with the Steam client works. Installing a custom version of Proton is fairly simple if you know the command line, basically just unpack it into the right folder. But if you prefer graphical tools you can use ProtonUp-Qt instead.

I'd try that since it's something you haven't tried at least. Check the first comment - all you have to do is install protonUp-Qt and then launch it. Use protonup to install Proton GE 7-55. Then, when you go to steam (might require a restart, don't remember) in the compatibility settings for the game you can set it to the Proton GE version.

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.
