Dishonored 2's steam store page has revealed that third party DRM software will be installed and required to play the game. The third party software is the Denuvo DRM software which many PC gamers have had multiple issues with in the past.
Gamers have complained that Denuvo Anti-tamper shortens the lifespan of solid state drives by writing excessive amounts of data on a consistent basis. The company responded to the claims by stating that the software "does not continuously encrypt and decrypt any data on storage media. To do so would be of no benefit in terms of security or performance." Yet remained hush about how the software actually works.
Any game protected by Denuvo requires an online re-activation for every hardware upgrade. Denuvo limits activations at 4 hardware upgrades per 24 hours. What is interesting is that many games use Denuvo such as Deus Ex: Mankind Divided, but don't post it on their steam page, which may be a result of the new Steam guideline changes that aims to make publishers more upfront about their product. Well, it's either that or it may be due to previous games removing the software after release.
The biggest issue from a consumer standpoint is the fact that Denuvo requires an internet connection to work. This means that should their servers go down or players have no internet, they will not be able to play the product they paid for. The always online connectivity requirement has been a source of great debate over the past few years and seems set to continue.
