Strange, Ive got nearly 60 hours on Steam Deck and never had one crash.Same here, I expect a lot of people here would agree with that to be fair. The physics lead to some really fun moments that I don't recall having in GTA V. The fact that police patrol the city, too, something weirdly absent from V.
I finished the story last night, I forgot I was going to make the opposite choice with Dimitri compared to my first playthrough at launch but I just hate him so much I guess I got blinkered into making the same decision again. I was going to 100% it but I lost 25 pigeons to a crash just now (it crashes a lot on Deck, quite often within a minute of waking it up) and can't be bothered, so I've moved on to The Lost and Damned for the first time instead.
Both expansions are great, TBOGT in particular is great and adds a lot of great weapons, vehicles and missions, but by far the best aspect of both the DLC's is the introduction of checkpoints in missions. I had some serious rage from having to replay whole missions on GTA4 after dying the most stupid unavoidable death lol
