Do note, Steam version doesn’t suffer from that somehow. Epic Games Store version does though.
With all same Wine/Proton (using Proton outside of Steam is possible) configs on same hw combinations tested ( multiple Nvidia gpu’s and couple of AMD gpu’s ) ;
1-) Steam version doesn’t hang on NV Windows,NV Linux and AMD prop Windows driver and RADV.
2-) EGS version hangs on NV Linux driver. Doesn’t hang on others listed above.
3-) EGS version seems to hang NV Linux driver at vkWaitForFences, likely related with some timing issue. Knowledgeable user who debugged this also sent an email to Linux bugs NV mail with a gfxreconstruct capture that reproduces the problem.
So key part is using Epic Games Store build of this game. On Steam version ( likely an older build or something like that ) it is not possible to reproduce.
