Yeah, and based on my search it looks like it had it right from launch, too. Though the steam page says denuvo anti-tamper, so maybe that’s not the same as the denuvo drm that (I think) uses encryption on certain parts of the code.
Fwiw, I didn’t notice any annoying performance issues. Apparently there is/was a stutter that was fps dependent, but the devs said they didn’t think it was related to denuvo.
Deathloop came out in 21. Though as mentioned to the other reply, steam says denuvo anti-tamper rather than DRM (and they claim to have pirated it a year ago), so this could be a different use case.
Just wondering if the anti tamper involves anything in the kernel now, since that was the use case that was originally targeted with kernel level code.
