Microsoft is doing a banging job, two years ago I had only a little bit of Steam Deck in there against Windows. And just mid October I put Linux on the gaming computer…
And play time too, I played a game for about 10 hours on the week I bought it but steam reported 600hrs.
Fortunately (or unfortunately) it corrected itself after playing on PC for a few mins, still if it hadn't, silly crab dark souls would have been my 3rd most played steam game ever
I saw that when playing a game, it counted the time since it was opened while playing. But always saw it correct itself to actual time running withing a few seconds/minutes of closing the game on the deck.
Can't believe a quarter of my playtime was The Witcher 3. I don't know if I would've even finished it if I played on PC, it's so damn long. I don't play much AAA though I guess, but JRPGs are long too.
Also, it just occured to me that I spent plenty of time emulating too though...
The other 6% was a few multiplayer sessions of Warhammer Vermintide with friends which I guess I could have played on the deck but I needed the KBM and bigger screen.
