Well, when the game is essentially running in a virtual machine with an address translation layer that scrambles the backing memory every few minutes you're lucky the game even runs. Good luck trying to decipher that hell. A few guys have done it, I remember the one dude ranting on Twitter about trying to crack Borderland's 3 back around launch.

And then the follow up which was that Denuvo was basically adding a ~30fps overhead to the game and everyone was initially blaming the devs for releasing unoptimized garbage.

Gabe had it right, piracy is a service problem. And my motto has always been if the game has some garbage like Denuvo, then you couldn't even pay me to take a copy. Not worth the headache.
