Capcom accidentally left a developer branch of Devil May Cry 5 public that didn't have Denuvo copy protection added to the files. A Steam user created a guide for downloading the file, but Capcom took the file down. Digital Foundry has tested the file to see the performance difference between Denuvo on and off. They experienced a 7% difference in performance between the builds, but only at low resolutions. Devil May Cry 5 is fairly light on CPU usage according to Richard Leadbetter. I included images showing the performance difference from the Steam user that created the guide. Left is with Denuvo enabled and right is without Denuvo. Assuming that the only difference between the two builds is indeed the inclusion of Denuvo, or the lack of it, the evidence looks conclusive. On the one hand, modern gaming PCs should have the CPU overhead to run the extra load incurred by what our tests suggests to be the Denuvo DRM. However, on the other hand, the notion of any DRM system incurring a seven per cent in-game hit to performance on a processor as capable as the Core i5 8400 (which runs six cores at a peak 3.8GHz) is certainly concerning. We've approached Capcom for comment and will update with any further information.
