Wild Hearts Steam Deck Gameplay - Unplayable?

Wild Hearts has some serious issues on Steam Deck right now, with 99% GPU usage on every setting, something is seriously wrong, 30 FPS is a dream for this game at the moment as we regularly sit at the 20 FPS mark even on the lowest settings. No Swap file fix or UMA Buffer increase is helping this either, so one to avoid until we get some patches.
