What is happening, what is it you think I said? Why did you come back a day later and make a second irrelevant comment?

Apple tried to create their own system for years but finally gave up recently and moved to Intel and Microsoft.

That person can’t be real…

You’ll be hoping for a while. This ain’t 2005 anymore.

It’s an arms race, the arms just keep moving deeper into the stack system. Used to happen entirely in usermode, one process poking in and reading/writing memory of the game, so anti-cheat started keeping an eye out for malicious processes. Then at some point someone patched their kernel to cheat in a way the game couldn’t possibly detect from usermode, so someone made an anti-cheat that ran at the kernel level too.

Modern KLA is basically a fully fledged rootkit, living in your system from boot, doing absolutely anything they can to try and make sure nothing has been tampered with. Validating signatures on bins, hooking memory mappings, watching for anything that might try to read/write the kernel or game’s memory space unexpectedly.

Casuals stop playing games when cheaters prevent them having fun, and it’s the casuals they need to keep happy to keep their game alive.

IMO the answer is to internally maintain a “fun to play with” metric. It would be specific to the game, but each player’s actions and interactions with other players would be evaluated to determine how “fun” they are to play with (might need to be multidimensional, since different players like having different types of interactions). It doesn’t matter if they’re cheating, or if they’re just really good, or if they use cheesy strategies, etc, if the person isn’t fun to play with, then match them with other people who are similarly unfun to play with.

This would cover your point that, if there’s a cheater in the lobby, and their behavior somehow makes everyone have more fun, then who cares?

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).
