It’s coming for Christmas.

This covers the in-game graphics settings; you will have to manually set your own TDP and find your sweet spot as every SoC is different in terms of stability. You can also undervolt your system, which gave me some performance boosts on some games and fewer stutters on others. This game is very old, and I doubt you’ll run into any issues playing it. You can even run it at 90 FPS.

I will port them over there.

Try Proton experimental.

Did you try playing it with proton experimental.

Yes, I left it to the end user to do it themselves so they could find their sweet spot.

The game doesn’t set the resolution to the appropriate ratio; the resolution just means that it will render the game at 1280x800 but will not view it in this resolution; it might be the engine’s characteristics.
