QuoteYou 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. https://www.gamingonlinux.com/forum/topic/3759/post_id=30722
