[Update]: Update 2 has now improved Empowered Demons and added a new Battlemode map.
A short while ago, Doom Eternal received a fairly hefty new update. It brought in Empowered Demons to spice up the singleplayer campaign, prestige leveling that lets you continue unlocking fancy insignias even after you've hit level 250, as well as an assortment of quality-of-life changes and bug fixes.
Unfortunately, all of the good stuff in the update was overshadowed by the inclusion of Denuvo Anti-Cheat in both multiplayer and singleplayer. Given that the playerbase was already riled up due to Riot's somewhat similar anti-cheat for Valorant making a big mess, the addition of Denuvo Anti-Cheat to Doom Eternal quickly resulted in massive amounts of complaints and negative reviews on Steam.
On the positive side, the story doesn't simply end there. After hearing all of the community complaints, as well as seeing the impact it had on performance for certain players, the Doom Eternal team has now removed Denuvo Anti-Cheat integration. You'll still need to uninstall it yourself through Windows' add/remove programs menu, but no matter what you do, it'll no longer play a part in Doom Eternal.
The small update has also fixed several crashes associated with skins, as well as a couple of memory related crashes that popped up since the recent update. So if you encountered any technical issues after Update 1, you might want to come back and see if things have gotten better with this new patch.
Have fun with Doom Eternal, and here's a brief overview of Update 1, just in case you've missed it:
