It is a problem, since it means people who cracked the game get a better experience than the people who paid for it.
DRM hurts performance, game preservation, modding but does nothing against piracy. Not to mention the fact that those DRMs are often kernel-level malwares and also hurt the overall system stability and security.
Denuvo is just the new Securom or GamesForWindowsLive, both didn't prevent piracy at all and just hurted the legitimate customer at the end.
Denuvo has been proven to affect performance drastically. You just have to play the Game Pass version of a game vs the Denuvo version, and you'll see that performance difference, from my own testing it could go as far as 40fps difference.
Yes, a bunch of Denuvo-infested games are pretty lightweight and well optimized, Hi-fi Rush for instance or Atomic Heart. But that isn't an excuse to waste performance and at the same time increase the system requirements for no reasons, just to bundle a malware.
Denuvo claims they've improved performance and what not, but we've yet to see this actually be true. Weirdly enough we got no news on that supposed experiment by Denuvo to showcase it doesn't impact much, wonder why
(Note that it would've been untrustworthy anyways, by the obvious conflict of interest from the people doing the benchmarks)
Though iirc, it doesn't auto-remove itself, though it is true that it is subscription-based (which makes it even more of a scam to buy in the first place lmao). From what i know, the game just won't boot if the publisher stops paying rather than the DRM self-uninstalling itself.
