I was curious, because it started on Deck out of the Box, but not on my Linux Machine (reported freeze on start). But with PROTON_USE_WINED3D=1 %command% it suddenly started and i was able to play. First, It crashed after 5 Minutes or so. With additional PROTON_FORCE_LARGE_ADDRESS_AWARE=1 no crashes so far, but i haven't played too long up until now. Complete launch argument String: PROTON_FORCE_LARGE_ADDRESS_AWARE=1 PROTON_USE_WINED3D=1 %command%
