The viewing options OP listed should all work with AV1, I think they were just worried by the preset names. Plus, hardware support should only get better.
OP, you should be able to adjust settings after you select a preset, so you can pick different dimensions/frame rates/audio codecs/etc.
Side note, I’ve found that the matroska container is the easiest one for me to use if I want better subtitle support.
Even on cars that support it, it has always told you that you need to close Steam to put the car in drive. They don’t let you play any games while the car is in motion.
It’s been a decently good feature to have; the few times charging was a bit slow for me, it was nice to be able to play FFVI or Secret of Mana to pass the time. And it even synced my saves for when I got back home.
