A few ambulatory vamp slaying jaunts later, I can conclude that it… maaaaaybe can.
Firing up Redfall on the Steam Deck is painless, with no incompatible anti-cheat orhateful launcherscausing headaches.
Personally, these temporary sub-30fps dips arent an instant dealbreaker when the majority of Redfall can perform viably.

Performance mode is a much better balance of speed and looks.
Lastly, a quick tip for those who find that the thumstick controls feel a bitoff.
This made crosshair movement feel far more consistent and manageable.
