Hello @Pentastarch, we're tracking issues with games run with Proton in the Proton issue tracker. Additionally, we're using one issue report per unofficially supported game title, so I've gone ahead and transferred this issue report to https://github.com/ValveSoftware/Proton/issues/3773#issuecomment-724115303.
Your system information

CPU: AMD Ryzen 7 3700X 8-Core

Steam client: Built: 4th Nov, version 1604538810
Steam Runtime Version: steam-runtime_0.20201104.0
Ubuntu 20.10
In the steam beta - yes
I upgraded from 20.04 to 20.10 and Doom Eternal stopped loading. It gets to the loading screen and hangs. Other games - Doom 2016, Metro Exodus load and run fine.
I have reinstalled steam and the game, verified the files but cant get past the load screen.
I did change the screen refresh rate to 60Hz from 144Hz, which worked prior to the upgrade, and it loads the next screen and the music starts. But then hangs there. but I haven't got any further.
Any ideas??
