You can just edit that code out from outside the hypervisor and no one will be any wiser.

this would be the case if there wasn't an external entity with its own timesource (i.e. the game server) interrogating your machine while the game in underway

if there's a VMEXIT it will be measurable, and you have no ability to virtualise the server's clock

That applies to any anti-cheating or copy protection code anyway, so I'm assuming this will be handled similarly.
