I managed to complete the game some minutes ago and I can conclude, that it does work perfectly with dxvk.
I didn't encounter any other issue besides the nasty launcher.
And about the game... just wow...

Yeah it works perfectly. I still haven't quite finished the game. It's pretty good game also, except the stupid spam E button stuff and the AI that is really really stupid at times and don't see you when you are 10m infront of an enemy. Playing with hard difficulty so its not too bad all the time, sometimes they cooperate nicely and hide and take cover etc, but sometimes they are really bugged and breaking the immersion a bit. Overall solid game though.

Hello to all.Suddenly Metro Exodus has lost the sound with all versions of Proton (official) and GloriousEggroll/proton-ge-custom.
Does anyone know how to fix it?

You may want to repost your question on Steam Play & Wine Gaming as its more appropriate for the topic and where you can find more assistance as this part within the forum isn't used to troubleshoot issues in games under proton or wine.

That being said, did you try entering this command on the Steam launch options:
PULSE_LATENCY_MSEC=60 %command%

If that doesn't work, try modifying the user.cfg files and place edit these following values with the appropriate integers:
 
r_enum_ssaa 0

r_ssaa_auto 0

r_blur_level 0

r_game_mblur_scale 0

Then save this configuration file and make it read only.

Thank you, but none of the solutions work.
Also, I have noticed that the game is not listed in the sound menu, it is as if there is no communication with the audio server.

Still waiting for this one to be released natively before I buy.

I think it's fair to say that the ME port has been quietly dropped.

does me port mentioned before ?
