involves the developer having to call into it on many phases of the game running

Absolutely, I’m not doubting that. That’s how denuvo works from what I understand. My point is that I am doubting that these calls would stall the system hard enough to cause any significant framedrops to be mad about.

If denuvo would result in like 20% performance loss, I’d be mad about it aswell, but everything I’ve seen so far points to a shitty implementation of denuvo that causes the performance loss, not denuvo itself.
