dxvk: Assassins Creed Black Flag crashes with DXVK

When playing Assassins Creed IV using DXVK it crashes as soon as I get to the first future storyline scene (Directly after maneuvering the merchant’s ship out of the bay at the beginning). The thing is that my whole system becomes unresponsive and I can’t even change to a different tty. So I had to reset my PC and I wasn’t able to retrieve any debug messages from wine. After trying a few times I was able kill AC and my X Server via ssh. But my log still stops way before the crash happens and doesn’t contain any error messages.

Anyway I tried without dxvk and the game works wothout any problems. Although using wined3d it’s pretty unplayable at ~5-10 fps. Whereas DXVK was easily able run with 60 FPS (capped at my monitor’s refresh rate). Which proves to me that the crash is at least DXVK related.

Apitrace file(s)

Unfortunately the game crashes about a second after going to fullscreen when started with apitrace (If I understood it correctly apitrace shouldn’t be executed with DXVK?):

$ &> apitrace.txt WINEPREFIX=~/Games/uplay/ LD_LIBRARY_PATH="/home/user/.local/share/lutris/runners/wine/tkg-4.0-x86_64/lib:/home/user/.local/share/lutris/runners/wine/tkg-4.0-x86_64/lib64:/lib:/lib64:/usr/lib:/usr/lib64:/usr/lib32:/usr/lib64:/home/user/.local/share/lutris/runtime/Ubuntu-18.04-i686:/home/user/.local/share/lutris/runtime/Ubuntu-18.04-x86_64:$LD_LIBRARY_PATH" WINEESYNC=1 WINEDLLOVERRIDES="xaudio2_7=n,b;nvapi,nvapi64=" DXVK_HUD=0 DRI_PRIME=0 ~/.local/share/lutris/runners/wine/tkg-4.0-x86_64/bin/wine ~/Dokumente/apitrace-msvc/x86/bin/apitrace.exe trace -a dxgi ~/"Games/uplay/drive_c/Program Files (x86)/Ubisoft/Ubisoft Game Launcher/games/Assassin's Creed IV Black Flag/AC4BFSP.exe"

However AC runs fine when started by the exact same command (just without apitrace):

$ WINEPREFIX=~/Games/uplay/ LD_LIBRARY_PATH="/home/cedric/.local/share/lutris/runners/wine/tkg-4.0-x86_64/lib:/home/user/.local/share/lutris/runners/wine/tkg-4.0-x86_64/lib64:/lib:/lib64:/usr/lib:/usr/lib64:/usr/lib32:/usr/lib64:/home/user/.local/share/lutris/runtime/Ubuntu-18.04-i686:/home/user/.local/share/lutris/runtime/Ubuntu-18.04-x86_64:$LD_LIBRARY_PATH" WINEESYNC=1 WINEDLLOVERRIDES="xaudio2_7=n,b;nvapi,nvapi64=" DXVK_HUD=0 DRI_PRIME=0 ~/.local/share/lutris/runners/wine/tkg-4.0-x86_64/bin/wine ~/"Games/uplay/drive_c/Program Files (x86)/Ubisoft/Ubisoft Game Launcher/games/Assassin's Creed IV Black Flag/AC4BFSP.exe"

Anyway here is the output of the apitrace crash: https://own.arrakiz.org/index.php/s/yJYdNy7zeqnzPnm (Just click download. The file is somehow too big for any kind of preview.)

I’m sorry that I couldn’t provide more debugging info. I know that a trace would be vital for a diagnosis. But at this point I’m not sure what else to do. If you give me instructions I’m more than willing to give you more info though.
