List below.
Depending on the game it’s resolution/framerate improvements, HDR support, mouse controls or gameshare/gamechat support.

- Clubhouse Games: 51 Worldwide Classics
- Game Builder Garage
- New Super Mario Bros. U Deluxe
- Pokémon Scarlet

FWIW, performance should already be better even without the DLC, just by running on better hardware. You just won’t get HDR and the phone app extras.
In this list of patch notes, the only games that specifically mention framerate are ones that had capped framerates - the updates are to uncap them. Any game that’s already not hitting its target/max framerate will benefit even without a patch.
