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.
It allows memory access across virtual machines as well, meaning the all cloud VMs are vulnerable.
The machines that are running cloud VMs should obviously be patched. I wasn't talking about those.
