Denuvo is DRM, not anticheat.

Right, I’m pointing out that as a purely single player game, how would one cheat in Doom: The Dark Ages?

Denuvo isn’t quite DRM either. It’s an anti-tamper layer; the whole goal being to prevent the binary from modifications. This then prevents the DRM of choice (ie Steamworks) from being bypassed.

I know that sounds a little pedantic; but typically DRM involves an identity layer (who is allowed to access what?). Denuvo doesn’t care about that; it’s even theoretically possible to make a Denuvo protected binary anyone could use.
