60 FPS limit
It's a game engine from the year 2000. Many bugs exist. But this is kind of the point with this release.
The game now ships with dgVooDoo installed which helps modern hardware compatibility on Windows but this mod does not get loaded on the Steam Deck. Lucky it does not see to need it and loads the DirectX 7?... via normal proton/wine methods. Switch to ProtonGE to get the cut scenes working and that is all you need.
For battery conservation I set the deck to 60fps limit. The game basicly runs entirely off the CPU so not running at 90fps limits the power useage of the CPU quite a bit.

Intro video did not play properly when launching from default compatability settings. Switching to GE fixed this issue. Game seems to play normally otherwise.

Edited GAME.INI and changed 'width' and 'height' to my monitor's settings.
The movie files will not play unless GE-Proton is used. To get a 1920x1080 resolution, I used the dgVoodoo2 guide from https://steamcommunity.com/sharedfiles/filedetails/?id=3462724739, and installed the files from D3DRM.zip, 3DfxSplashDlls.zip along with dgVoodoo2_86 into the game's root directory.
