Castlevania: Belmont's Curse performance on Steam Deck, ROG Ally and Intel handhelds

Testing the full PC version ahead of its planned October 15, 2026 release, RPG Site says changing Proton versions and GPU clocks did not make Steam Deck performance feel good; it recommends waiting for patches. On ROG Ally, it reports 65–110 fps in tested areas at 25W after setting the refresh rate to 120Hz or lower. Its Intel handheld tests found 60-plus fps at 1080p.
