Denuvo was basically adding a ~30fps overhead
I’m very surprised when I read an announcement that id software were removing denuvo from doom eternal. The game was running very well on weak hardware I never suspected it has denuvo at all. After denuvo removal, I tried running the game again and didn’t notice any difference in performance. Maybe id software is an exception here and they worked some magic with their denuvo integration.
Doom Eternal actually released without Denuvo by accident, they quickly patched it in but the unprotected exe was already available for all so if you played it on day 1 you actually played it without Denuvo.
I didn’t play it day one though because I’m, uhm, a patient gamer.
It’s cause Vulkan is so optimized. You can run the game with Ray tracing and still get like 200fps
