Over 50 PC Games Are Incompatible With Intel's Alder Lake CPUs Due To DRM
An anonymous reader quotes a report from PCMag: Intel has posted a release that the hybrid CPU core architecture on Alder Lake can be incompatible with certain games, specifically some protected by the anti-piracy DRM software from Denuvo. This was confirmed in our review of the Core i9-12900K when we tried to run the hit AAA Ubisoft title Assassin's Creed: Valhalla, part of our processor benchmark suite. The game would crash halfway through the test run, or simply not boot in at all. The errors occur because Denuvo's DRM software will mistakenly think the so-called "Performance-cores" and "Efficiency-cores" (P-cores and E-cores) on the chip belong to two separate PCs, when in reality the two types of processing cores are running on the same Alder Lake processor. (This P-core/E-core design is a new trait of Intel's chips with Alder Lake.) Intel was originally mum on which specific games were affected, making it unclear the scale of the problem; the company cited "32" in pre-release briefings to the tech press. Whether these would be marginal titles or blockbusters we did not know, as hundreds of games use the Denuvo DRM scheme. But on Thursday, the company published a list of every PC title known to it that has incompatibility issues with Alder Lake. It spans 51 games, including For Honor, Mortal Kombat 11, Star Wars Jedi Fallen Order, and Shadow of the Tomb Raider, as well as the Assassin's Creed: Valhalla game we observed the issue on. Intel says it is working with game developers to roll out a software fix, although the company notes that some of the affected DRM-protected titles can run fine, so long as your PC is on Windows 11. In the meantime, the company says it has come up with a workaround that can run any of the affected games on Alder Lake. But it'll do so by placing the efficiency cores on standby. "According to Intel, 22 of the games won't work on Alder Lake under both Windows 10 and Windows 11," adds PCMag. "[T]he remaining 29 titles [...] will suffer incompatibility problems, but only when run on Windows 10. So owners can also solve the issue by updating their PCs to Windows 11 or using the Scroll Lock workaround if available."
