Yes and no. I have a Steam Deck and a Macbook M1 Pro, my previous Windows PC is from 2010, it ran Overwatch 1 at about 30fps on a good day and managed through multiplayer Valheim games during covid lockdowns =)

I _can_ play something like CP2077 on the Deck, but it's not exactly a worthy experience, it's better suited for stuff like Citizen Sleeper or Rogue Trader
