I personally have a huge backlog of games I'm happily playing through on the deck. And, having been burnt a few times (Cyberpunk, No Mans Sky ..), I very rarely buy new full priced games anyway (better to wait for a discount and some patches!)

But according to this rather clickbate article ...

In the last month alone, we’ve seen three disappointing examples of games that are too demanding for the Deck. Star Wars Outlaws is unplayable on Low settings, even with FSR set to “Ultra Performance.” Warhammer 40,000: Space Marine 2 can’t reach a steady 30fps at the lowest quality setting. And based on the demo, Final Fantasy 16 is unplayable without FSR and Frame Generation, and afflicted with stuttering and horrible frame pacing with those scaling features enabled.
