Sadly this game is a lost cause on Steam Deck. Not surpising as It needs a fairly decent PC to run, it even runs at a pretty low base resolution on PS5, but the ProtonDB Gold rating would have you believe it's a decent experience. Even at the absolute lowest settings you can use, which look absolutely terrible, it doesnt seem possible to wring a playable framerate out of it and this is a game that benefits from a high framerate and decent visibility. It's a shame, the game would be well suited to the Deck but unfortunately it's not gonna happen.
