Nah, but most PC games don't take advantage of the SSD.I'm sure they're closer now? Last time I tried it was with Metroid. The cutscenes weren't playing, but the game itself played exactly from beginning to end.
So like 98% of the time, there's not much of a difference.
There is an emulator, but it's a work in progress. Might be able to play some games on it, but you're not going to be replacing a Switch with a SteamDeck any time soon
