Yup.
The previous family share was gathering your library of games with the “console” in a single box and giving that entire to your friend. If you want to play anything, you need the box back.
Steam Families is now a common bookshelf, grab a game if it’s there and play.
Now we just need a way to use that shelf with the same account so I don’t get booted from my steam deck games just because I left something running on my PC and vice versa.
One technical reason for why FSR 1 isn’t very good but works in everything is that FSR1 is the only one that just takes your current frame and upscales it, all the newer ones are all temporal - like TAA - and use data from multiple previous frames.
Very simplified, they “jiggle” the camera each frame to a different position so that they can gather extra data to use, but that requires being implemented in the game engine directly.
