AAA Gaming, I feel, could use a lot of optimization these days. Hopefully a bad GPU market and the steam machine might force the developers to deal with that.
I've been waiting for Spider-Man 2 to run well on my steamdeck ever since it released (1 worked quite well).
Meanwhile I have been playing a bunch of AA, indie games, older AAA titles on it and am fairly Happy. (Road Redemption, Cleared Hot, Tomb Raider 2013).
The only AAA game I'm looking forward to is Project 007 but I'm not even hopeful it would run on any of my machines.
