--- Comment #8 from Jonathan Strander mblackwell1024@gmail.com --- Created attachment 55372 --> https://bugs.winehq.org/attachment.cgi?id=55372 Wine 1.9.16 Crash Log
Since the game never actually starts (just crashes) you don't get anything new from adding +d3d11
This log is with a new prefix that has only Steam and The Witcher 3 installed on it. No fiddling with any settings of any kind in Wine - just installed Steam, downloaded game, and pressed Play.
