@shoober420, same as the rest of your recent comments. You've disabled the Steam runtime and encountered a missing dependency. Disabling the Steam runtime is not supported.
LOG:
steam-3270.log
Game runs, but is limited to 1280x1024, and I'm not sure if this is a thing on Windows too. If it wasn't for this, I would of did a Whitelist Request.

fixme:vulkan:X11DRV_vkCreateWin32SurfaceKHR Application requires child window rendering, which is not implemented yet! is in the log, so something has gone awry. (https://bugs.winehq.org/show_bug.cgi?id=45277)
changing the Screen Resolution (higher than 1280x1024) works for me.
