When the game actually functioned, you had to use the following to get it to run:
M1 Pro, 16gb ram. Bottle: Windows 11, D3D Metal + Msync. Game: Enable DX12 to reduce in-game graphical errors. Graphical settings to Medium or (even better) a mixture of Low and Medium. Launch game windowed, then hit green corner button to enter fullscreen, not the settings. 1080p flawless.
