> it’s not acceptable to leave 5% performance on the table whereas for other uses it usually is.

I think that’s an incredibly rare stance not held by the vast majority of gamers, including competitive ones.

I don’t think a sandbox like a VM would work even if it could be done with only 5% perf hit? Wouldnt any game run in a VM be possible to introspect from the hypervisor in a way that is hard to see from inside the VM? And that’s why these anticheats disallow virtualization?

That would mean those who are concerned about the integrity would want to sandbox everything else instead. And even if people are ok with giving up a small bit of perf when gaming, I’m sure they’re even more happy to give up perf when doing online banking.
