d3d11: failed to create vertex buffer Crash Workaround.

[Blorf]

There is a very rare crash with DirectX 11 that seems common to Unity games. If you get a freeze then crash, check your output_log.txt file. If you see a ton of "d3d11: failed to create vertex buffer", then do this.

Log file location:
C:\Steam\steamapps\common\SPAZ2\SPAZ2_64_Data\output_log.txt

Word around:
Right click Space Pirates and Zombies 2 in your Game Library
Click Properties
Click Set Launch Options
Add: -force-d3d9


Example of the error in the log:
d3d11: failed to create index buffer of size 108 [0x887A0005]
d3d11: failed to create vertex buffer of size 96 [0x887A0005]

Other Symptoms that this workaround worked on: The game won't launch past the intro on either graphics cards. I can hear the intro stuttering and i can see the cursor, but after that the game just crashes.
