Steam Deck is one of the best and most powerful handheld gaming consoles out there right now, that's capable of playing more than just the games in your Steam library. That's right, you can even add non-Steam games to your library and play them on your Steam Deck. Heck, you can even use Sony's Remote Play feature to run PlayStation games on your Steam Deck and play them from anywhere in your home. If you have both a PlayStation 5 and a Steam Deck and are wondering how to play your PS5 games on Valve's handheld, then you've come to the right place.
