Rockstar Games has revealed a new DRM scheme they are instituting on Grand Theft Auto 5 for PC.
Called Denuvo, it uses a new code every time the game is opened, circumventing any attempts at piracy. Denuvo will work on the game on top of Steam, and is, in fact, already in use in Lords of the Fallen and FIFA 15.
Notably, Lords of the Fallen players are complaining about issues because of the system. Of course, GTA 5 is expected to pick up a considerably larger userbase.
