It's been a long time since I've actually played Skyrim:SE, but I vividly remember of it working on Proton back when I used the non-Exp Flatpak build, albeit I'd need to tweak my launch options to this:

WINEDLLOVERRIDES='xaudio2_7=n,b' PULSE_LATENCY_MSEC=90 %command%

Well, I just tried playing the game again using this Proton-Exp build, but the infamous silent NPCs issue seems to be back. However, when I switch to the official Proton Experimental, it works, so I assume there's something wrong with this build...?

This is the Proton-Exp version I'm currently testing (it's a fresh Wine prefix too):

Not sure if it's relevant, but I also have installed these two ffmpeg Flatpak packages:

org.freedesktop.Platform.ffmpeg-full
org.freedesktop.Platform.ffmpeg_full.i386

Thanks.

Hi,

I have the Proton community build, Proton-GE community build and Proton experimental community builds all installed. However, while the former two show up in my Flatpak steam client, Proton experimental does not. How can I make it show up? I have tried uninstalling the regular Proton community build (perhaps there was a conflict) but that did not help.

Proton (community build)                          com.valvesoftware.Steam.CompatibilityTool.Proton                 6.3-2                            beta               flathub-beta             user

The build has been failing.

Hi! Could this be updated for 5.13-20210217? This update is particularly interesting since it has the futex2 patches available for testing.

Thank you for your time!
