What works are the installation, menu, credits, options menu (including changing the resolution), sound, music.

The game starts.

What does not

Additional Comments

Game runs at about 2 fps, despite using about 110% (1+ core) on an i7-4770K system with a GTX 1060 6G and 16GB DDR3. Tried to make the demo game playable by:

• Switching from 64-bit to 32-bit-only (removed ~/wine, used "export WINEARCH=win32"). No visible improvement.
• Switching to Windows 95 mode with winecfg. No visible improvement.
• Switching the game from 1024x768 to the lowest available resolution (640x480). No visible improvement.
• Changing DefaultDepth and Depth /etc/X11/xorg.conf from 24 to 16, because the console displayed errors "0009:fixme:x11drv:X11DRV_desktop_SetCurrentMode Cannot change screen BPP from 32 to 16". This changed the errors to "003c:err:d3d:context_choose_pixel_format Trying to locate a compatible pixel format because an exact match failed.". No visible improvement.

Nothing I've tried appeared to improve the frame rate.
