I’m waiting for the book version of this video.

It varies quite a bit. I have an i5 with a 740M (2013) that is just barely supported. For reference that will run 360-era games fine given drivers. My 320M (2010) gets no love at all.

When you buy Nvidia for Linux, you’re buying obsolescence. It will work fine for a while and then they’ll hard-drop driver support at a certain kernel version. Your 3d acceleration will last as long as you can run an LTS kernel compatible with it. You may have moved on by then, but I currently have 3 Nvidia laptops that have between limited and zero 3D support in Linux. If I cared to run Windows or MacOS, 3D would still work. MacOS would also be outdated, though. In the future, I’m going AMD only.

That is an uphill battle - especially with tech illiterate users in your family.

Only some games support cloud saves on Epic. Strictly speaking this is also the case on Steam, but games without cloud saves there seem rather rare.

Overcast for iOS is very good, has a fully free tier and it is cheap to support if you want to.
