This turned into me writing a program that tries to detects if it's running inside of a #VM. So I can then try to make the VM less detectable. And because I was using the #RDTSC and #CPUID instructions I continued developing my CPUID program that I've never finished.

A classic rabbit hole.
"I want to do this. But that means I have to do that. Which means I can continue that other thing I've started doing some time ago." :derp_dog:

Краткое сравнение популярных функций измерения времени

Какую реальную точность можно ожидать от функции возвращающей время, а сколько времени она выполняется сама? Попытка замерить и сравнить несколько десятков функций, доступных программисту на C++. Вот что получилось
