Hello @Gibitwit, please add [`PROTON_LOG=1 %command%`](https://github.com/ValveSoftware/Proton#runtime-config-options) to the game's launch options, reproduce the regression, and attach the generated $HOME/steam-$APPID.log to this issue report as a file. (Proton logs compress well if needed.) Also, please copy the contents of Steam Runtime Diagnostics from Steam (`Steam` -> `Help` -> `Steam Runtim...

    Good to hear. Unfortunatly I will not be able to test it anytime soon. My system configuration has changed greatly and I do not have a Linux installation at the moment. It will probably be a while.

    There is an **enormous** performance regression using later Proton versions than Proton 9.0-4. :( Also it turns out older versions of OpenAL Soft do work. I hadn't accounted for Steam overwriting the DLL.

    HURAY! After updating OpenAL Soft to version 1.24.2 the 3D audio now works, seemingly all good. More play testing. It still does not work with hardware OpenAL. The game's performance on Linux is still poor and worse on G...

    Running the game via Steam play now has performance at the level of running the game via Bottles. Still far below windows. OpenAL/OpenAL Soft 3D audio still does not work.
