The behavior is the same for both versions. Switching back to 3.7-8 does not solve this crash. Link to full system information report: GistĪll 3 games were working perfectly with 3.7-8 until the 3.16 update. Driver/LLVM version: mesa 18.3.0-devel from Padoka PPA, LLVM 8.0.0 Name of the game with compatibility issues: Dark Souls PTDE, Dark Souls II Scholar of the First Sin, and Dark Souls III Dark Souls PTDE (and 2 and 3) are crashing on launch for me since the Proton 3.16 update.
