Kernel anticheat is seriously bad, and shouldn't be allowed on any computer. Kernel anticheat is basically installing full access backdoors to your computer that you have no control over. Attackers and malicious devs have used kernel anticheat to install ransomware, spyware, crypto miners, and more. They also frequently cause increased system instability and crashes.

Kernel anticheat typically runs from the moment your PC is turned on, and it's job is literally to spy on you to make sure you're not cheating. Among other things, many take constant screenshots of your PC to see what you're running. In this day and age where every company is spying on your and selling your data, installing kernel anticheat is literally sharing 100% of what you do on your PC with a company (usually chinese company) and trusting them to not take advantage of your data.

Furthermore once you've installed kernel level anticheat, there's no way for users to reliably remove it. Most anticheats will reinstall themselves if removed, and it's basically assumed that once you've installed one, your system is permanently compromised. They can create backdoors on the PC to allow reinstalling themselves in the future, or even install other software without your knowledge. There are concerns about them batching your bios, so that even a full harddrive wipe won't be able to remove their backdoors.

Finally, the whole point of kernel anticheat (to players) is to prevent cheaters, but that doesn't even work. Games like valorant are filled with cheaters despite using kernel anticheat. It's just led to a bunch of kernel level cheat software that's still able to hide from anticheat. So players are giving up their PC security/etc for basically no real gain.

I sure hope not. I don't want gaming on Linux to be turned into something where you need to run steamOS to be able to play certain games or be dependent fully on Valve, instead of any distro you like.

I don't want to switch Microsoft with Valve. I want my operating system to be completely mine.

I am already annoyed with how certain programs like Geforce Now's new native linux client is advertised as a SteamOS client and that it only works on a steam deck.

I don't know if it does only works on a Steam deck but they sure advertise it as such.

Lots of other games to play.

Linux is too secure to trust with their rootkits.

If even Microsoft was/is considering giving custom kernel modules the boot and potentially not allowing them in the future (due to similar but unrelated issues) why should the Linux community embrace proprietary kernel modules from companies who's goal is antithetical to the user, and which are probably horribly insecure and/or rootkits themselves.

Signed Kernels are problematic for some users. While the distribution-supplied kernel binaries are fine for most users, there are always those who want to (or need to, due to hardware quirks or bugs) tinker with the kernel compile-time configuration, or the kernel source code itself...

Time will tell, there's progress towards proper open source drivers for Nvidia now, but I don't know how long that will take to catch up.

Good. Fuck that shit.

Doing this in driver doesn't work very well as UI elements will also be affected. It should be implemented in games directly
