Yep. The approach that Denuvo utilizes has been discussed forever, but games didn't really have the extra CPU cycles to run around and validate the integrity of each and every function. Most games are balls to the wall and using every CPU cycle it can. Point is, games that require heavy performance suffer under Denuvo unless your system is bleeding edge. This means the vast majority of their customer base suffer. There are all sorts of ways to prevent piracy for games.. but most companies can't utilize these approaches due to the very nature of disorganized game development.
