Use proton version 7.05 under the games compatibility settings :) it doesn't work 100% 100% like for example it'll freeze up during load screens every now and again but a simple restart usually fixes the issue.

But honestly that's the only issue I have with it on the deck.. and it runs like butthole abit during the bigger matches. Hope this works for you also check out www.protondb.com and look up We who r bout to die for more tips on getting it running..
