Denuvo, an anti-tamper technology and digital rights management scheme, isn't doing a very good job preventing PC games from being copied. According to Ars Technica, Denuvo releases are being publicly cracked within a day of their launch. From the report: This week's release of South Park: The Fractured but Whole is the latest to see its protections broken less than 24 hours after its release, but it's not alone. Middle Earth: Shadow of War was broken within a day last week, and last month saw cracks for Total War: Warhammer 2 and FIFA 18 the very same day as their public release. Then there's The Evil Within 2, which reportedly used Denuvo in prerelease review copies but then launched without that protection last week, effectively ceding the game to immediate potential piracy. Those nearly instant Denuvo cracks follow summer releases like Sonic Mania, Tekken 7, and Prey, all of which saw DRM protection cracked within four to nine days of release. But even that small difference in the "uncracked" protection window can be important for game publishers, who usually see a large proportion of their legitimate sales in those first few days of availability. The presence of an easy-to-find cracked version in that launch window (or lack thereof) could have a significant effect on the initial sales momentum for a big release. If Denuvo can no longer provide even a single full day of protection from cracks, though, that protection is going to look a lot less valuable to publishers.
