Denuvo Anti-Tamper is the DRM-related technology that is supposed to combat software piracy but it had been criticized for hindering the performance of certain games released on PC. The popular examples had to be the AAA games released on PC that make use of this technology but some non-AAA games that use it had a similar problem. Some of the games were eventually patched to make the performance be on par with the DRM-free versions. Even the director of Tekken 7 put the blame on Denuvo technology for this problem and many gamers have been against that technology as a result.
With regards to the upcoming "Switch Emulator Protection" technology, the gamers are really concerned about the hindering of the performance of the Switch games as the console isn't that much of a powerhouse to begin with when compared to the competing game consoles such as the Playstation 4, Xbox One and their successors. The way the technology is implemented is that according to GamesRadar, there will be some checks inserted into the code where a specific Switch game containing such implementation will be prevented from being played on the Switch emulators on PC. Perhaps, the videos of Nintendo games being played on emulators on Steam Deck must have attracted a lot of attention recently and I guess that this is how Denuvo responds with the latest controversy they're going to cause.
According to Kotaku, there won't be online checks for the Switch games that make use of this "Switch Emulator Protection" technology, which means the solution is completely offline as the Switch console is a hybrid of a home and portable game console, so the full online capabilities of the console take place indoors. At least, this is not like the TRDR Pocket console which is an ANDROID-BASED PORTABLE console in which you're out of luck in trying to play tons of freemium mobile games on the go without Mobile Data turned on and SIM card inserted. But why would anyone want to play a portable console on the go in Online Mode? A smartphone could have been handy enough for browsing the net on the go, provided you have Mobile Data turned on and the SIM card inserted. It's already stupid to include 4G on a previous portable game console like the PS Vita and the same technical stupidity had gotten bigger with TRDR Pocket.
The latest controversy that affects the Switch had people thinking if Nintendo is involved in this or not but Denuvo made a recent claim that they developed this technology as a request from various publishing partners and Nintendo itself wasn't involved. It's basically causing gamers another hesitation on playing those games that have the Denuvo technology on PC and Switch.
One imagination from me is that the delusional shills of the Amico console may or may not be proud of a news like this for once when it comes to the Switch even though the Intellivision offices were empty for months and the game development for Amico games already came to a halt sometime ago. Certain Amico games looked like they didn't run at 60FPS or some sort when being shown in action. Sure, they might be family-friendly games but those shown were 2D GAMES and even certain family-friendly games with 3D graphics on Switch that don't run at 60FPS have superior graphics and more interesting presentation. The inclusion of the Denuvo technology on Switch games is one thing that may or may not get those shills surprised but the on-going concern from gamers about hindering of the performance of some Switch games should outweigh that surprise nobody cares. Imagine that the Amico console did come out with games released on it that used disastrous DRM technology that worsened the performance even further despite most of the games being 2D, that would make Switch and PC games with Denuvo more interesting although this is something no delusional shills of the Amico might care. A bigger problem involved the inclusion of such disastrous DRM technology in Amico games combined with the console lasting less than few years.
What about a 2D game that doesn't run at 60FPS despite having NO Denuvo technology at all? There were such NES games like that in existence and I guess it's due to game development incompetency but that sounds like a story of another time. Also, no matter how much optimization is put into the game, the Denuvo technology when included is already a big obstacle to the game's performance.
