Linux

Got to protect users from someone doing script assisted kick flips

For that matter, don't put any fish at all in a tiny bowl of water, especially without a filter or heater. The common goldfish is meant to be very long-lived and gets fucking enormous if you don't torture it to death in a puddle of its own urine.

Interesting assessment. I always correlated anti cheat to "our enshittified game isn't selling as well as projected. It must be piracy and cheaters"

Something about the kind of person who has such a need to prove their ability to shoot other people in a game that they're willing to give a corporation complete control over their home PC...

cm0002 has had a lot of spamm-ey accounts across several different domains. I block all of these accounts when I come across them myself

I'm not sure that is what they are advocating for. They have VAC which doesn't require kernel level access. If anything they will probably advocate this and that anti cheat can work without root level access.

As long as Valve is committed to an open system, without locked down bootloader like on mobile phones, it is unlikely that kernel-level anti-cheat can be implemented.

But that also means Steam Machines are unlikely to support 4K streaming from Nextflix and co. because also DRM will also only be on the level of other Linux systems.

Kernel level anticheat still can't detect all possible cheats, like Neuromuscular Aim Assist.

People say "kernel level" anticheat as if that would be necessary for some reason, but I don't really see it catching on in the linux world. Steam doesn't even have root normally. Even if it did, not everyone runs exactly the same linux kernel and the only practical way to distribute a module that's going to work for most people is through dkms, which means you build it from source, which means proprietary super-obfuscated shit is not going have its intended effect (assuming it ever does.)

There's nothing stopping them from doing all the same bullshit in userspace instead.

Only if we can also gatekeep them from using Windows. And games.

I think if you switched you would enjoy it so much more than Windows that you would prioritize Linux over the games with incompatible anticheats.

In due time though. Linux will always be available to you and eventually it will be suitable for your needs as well.

What about devs removing kernel-level anticheat?

I thought you were being facetious and joking lol

"I'd totally switch to Linux if I could install spyware into my kernel"

I've been running Linux for many years now and for those games that need it I reboot to Windows. It doesn't happen a lot. So many games just work on Linux, I just play those.

Build your netcode with "never trust the client" as your first rule

I wish this were more prevalent. Server side anti cheat is a problem that money can be thrown at and solved but its cheaper at face value to lease that labor from anti cheat service contracts.

We have memory security, virtualization and antitampering features

As someone who games entirely on Linux and wants multiplayer to work out, the features you're referring to are for keeping the application contained by the kernel, not the other way around. On a system where the user has full autonomy, no application should be able to know what is going on outside of its user space, and I don't want it to.

It'd be nice if it was a solved problem, but it's not. From consoles to phones to windows, currently the industry relies on you not having autonomy over your device for anti-cheat to work. Every other solution is either expensive (obfuscation arms race), or untenable (real time, high resolution server side validation of every property of every player).
