Those were ports that dynamically loaded the game to maintain high frame rates at the expense of graphical fidelity, seems like that takes a bit of work to pull off which is where we run into the paradox of adoption. Doing extra work for the Deck as a target platform would increase adoption rate of the Deck, but there’s no reason to do that until enough people adopt the Deck to make the work worthwhile. I hope Steam puts more weight behind the Deck as I could see a comparable Windows device overtaking it and competition is already on its heels.
