measure for Nintendo Switch titles intended to block play of emulated games.
Nintendo Switch owners on social media widely criticized the announcement of this software, expressing concerns that it would hinder software performance, citing Denuvo DRM's history of being reported as impacting PC gaming performance.
However, Denuvo said in statements to the press that it would not negatively impact performance of Switch games for those playing on real console hardware.
Denuvo declined to disclose the names of any other companies involved, but said that Nintendo was not involved and that there had been "strong demand" from software publishers for such an anti-piracy measure.
The developers of Ryujinx responded to the announcement in a tweet, stating their intention to continue developing the software.

Dustin Bailey of ''GamesRadar'' characterized this action by the company as curious, considering both that SteamGridDB only hosts images and not any pirated copies of games, and images of many other Switch-exclusive games were hosted on the site. Bailey therefore concluded, "It simply seems Nintendo is taking whatever strange, small steps it can to keep its biggest Switch games from being associated with Steam or the Steam Deck."
