""I think it's super hard for a gamer," Ullmann tells Rock Paper Shotgun. "I'm a gamer myself, and therefore I know what I'm talking about. I think it's super hard to see, as a gamer, what is the immediate benefit for me that a certain game developer, game publisher, is using our anti-piracy services." This gap, coupled with the fact that Denuvo "simply works" and "pirates cannot play games" which use it, as Ullmann puts it, are two main contributors to its negative reputation, he argues."
Let's not forget about being always-online or not being able to test different wine/Proton setups for fear of activating the DRM. Or even trying simply to run the game in some situations...
You seem to be arguing it's all about the implementation of the phoning home itself- I'm arguing that running the entire executable/binary through a virtual environment likely has far more drastic performance implications than a phone home, regardless of frequency. It probably IS mostly an implementation problem, but I'm more inclined to believe that the implementation of the Denuvo virtual environment is at fault, not just a server call and response delay. **EDIT: Apologies, forgot to include a link- see HERE. Looks like a substantial/measurable difference. Not massive, as measured here, but certainly enough that if your hardware is just barely able to run a game it could easily make or break the entire experience.
