Microsoft quietly deletes Windows 11 doc pushing 32GB RAM for gaming after outrage

I think you're right. Like, most software hasn't functionally changed much since the days it required 512 MB RAM and came on a DVD-ROM. I guess optimisation isn't really a thing nowadays.
But also I think PCs could get by with less RAM, too, if they only let you run one app at a time (with no background apps). 😃
