Both Doom and Wolfenstein have had patches to further improve performance since release.
Honestly, Doom is a bad experiences docked. Even with motion aiming, I think the frame rate, image quality and audio quality compromises are too much to recommend Doom to anyone.
But in handheld, it's Doom. It's Doom 2016 running in handheld and it is very playable and looks great.
I don't think there is any other Switch game I feel this way about. Do not buy Doom for Switch if you intend to play it docked. Do buy it if you want to play Doom handheld. It's an amazing game to have portable.
I don't love Wolfenstein enough to double dip on Switch. With how cinematic that game is, I dont think I'd want to play it handheld. But Doom is so gameplay focused and it just works handheld. Shame the digi version is 22gb. That's a lot of space on an sd card.
