But that's, like the one place other than games where consumers are looking for performance. What's left, web browsing and MS Office?
I just skimmed through the article and it seems like this vulnerability is only really meaningful on multi-user systems. It allows one user to access memory dedicated to other users, letting them read stuff they shouldn't. I would expect that most consumer gaming computers are single-user machines, or only have user accounts for trusted family members and whatnot, so if this mitigation causes too much of a performance hit I expect it won't be a big risk to turn it off for those particular computers.
Would it mean that a malicious application being run in non-admin mode by one user could see data/memory in use by an admin user?
It would indeed imply that which is why this vulnerability is also serious for single user contexts.
