I don't have V-Rising, and I'm sure a lot of this stuff is hardware dependent, but according to a couple of reports on ProtonDB, there might be a kernel bug causing issues with it.

I just installed bazzite on my LCD Steam Deck this week and it has been pretty solid so far, but obviously the hardware support for it is top notch thanks to Valve. I didn't have really any issues with regular SteamOS either and just wanted to try something a bit more customizable.
And really Linux gaming on the Steam Deck feels like cheating, especially compared to trying to run games via wine before the proton days.
You literally just described American healthcare. I don't know where people get this idea that you don't have to wait to see a doctor here. I've had to book doctors appointments months out. And specialists can be 6+ months of waiting.
I think the Americans that say otherwise actually don't try to go to the doctor on a regular basis. And if you press them on why, they'll admit it is a fucking hassle and worried about the bill if they need to actually get something done.
