A short performance test of Fire Emblem Warriors Three Hopes on Steam Deckwith Ryujinx emulator.
Power Tools with processor OC makes a noticeable improvement in performance, but temperatures reach 100 degrees. Steam Deck draws over 25W in this mode. I have no intention of playing with this temp and power drain, I just did it for preview. Without OC the game usually runs at 10-20FPS – we have to wait for Yuzu patches or adding Vulkan to public Ryujinx release.
