Hello everyone,

After a more than a month since Doom Eternal was released, we now have important changes to be aware of on PC:


Doom Eternal is now forcing you to install Denuvo Anti-cheat or "DAC", which is kernel level. Even though I don't have much in depth knowledge about windows operating systems architecture, nor do we have access to Denuvo code (the whole thing is obsfucated), I still have pretty good theoretical knowledge about linux OS's and kernel vs userland (and since we are using Linux, you surelly do too).


To me, the biggest problem with is the fact that the software is brand new and that it has bugs (like every software), which would lead to system crash...; also security issues will be found (the driver itself can still be reverse-engineered (we nowadays have strong tools such as: NSA's powerful ghidra tool[ghidra-sre.org] or even disassembly if one has the patience).


As for the potential intrusive data collecting process that could be done (surelly is done), it is to me not so worrying as the security risks (windows in itself, facebook, google... are spywares). With windows being an OS spyware in itself, every windows OS allready has a kernel level spyware. Nevertheless it doesn't mean that it's ok, since it is one more way data is collected and therefore one more entry point for data leaks... (has a data-science engineering student I get why companies need data, AI is nothing without it, I just feel like kernel level driver and potentially spyware for a singleplayer game is an unnecessary risk to take).


This leads me to the singleplayer game experience. They are reports on FPS drops, slowdowns, game crashes and so on... (Note that Denuvo is apparently required to be installed for you to launch the game even offline; I already uninstalled Doom Eternal, so I could not tell).


Last but not least, the game is now broken on Linux.



Let's hope that Id will convince Bethesda to fix this at least for singleplayer mode. But let's not just hope, we can act towards it on social medias (twitter mentions on bethesda and Id), asking for refunds (I personnaly am way past the refund date), mailing customer service, negative reviews on steam are rising...

• r/Doom reddit article (lots of r/Doom contents related to Denuvo btw).
  
• Modern Vintage Gamer's video (this guy does quality content btw check his channel ;)
  
• EULA states it (it is impressive to see how big publishers manage to get everything right towards law but are unable to check game files at launch Day 1 broken DRM protection[arstechnica.com])
  
• Bethesda's update twitter post

Any productive comment is welcomed
