Total War: Warhammer 3, like many modern video game titles, uses Digital Rights Management (DRM) software to prevent piracy. One of the most famous and notorious pieces of DRM software is Denuvo. Denuvo Anti-Tamper, to give its full name, is a DRM software that reportedly has an adverse effect on game performance due to its high CPU usage. But does Total War: Warhammer 3 use Denuvo?
In short, yes. Total War: Warhammer 3 uses Denuvo. It was previously thought that Denuvo was absent from the game, especially in Press and Content Creator versions released for early access. But in a recent blog post, Creative Assembly confirmed that Denuvo was included in the game from the beginning.
It also clarified that Denuvo has been a part of previous Total War titles, and denies that it is causing some of the performance issues that Total War: Warhammer 3 has suffered with.
However, in the blog post, Creative Assembly did state that "the impact of Denuvo on performance is not yet conclusive." They went on to state that many players have presented evidence both ways, and there are likely to be many factors that affect performance outside of Denuvo.
Ultimately, Total War: Warhammer 3 does feature Denuvo DRM, but it's inconclusive whether that affects the game's performance.
