Aside: are there any good tutorials that provide an overview on how to write such an anti-cheat?

#22Probably going to make it proton-incompatible, I'm guessing.
Valve have been working with anti-cheat providers for the release of the Steam Deck. Will be interesting to see how this turns out though.

#23Earlier quoted context omitted.
If I write a cheat for your game that operates on the kernel level, how would you detect it from the game that runs in user space?
Next will be cheats that run in hardware themselves ... I wonder if it's possible to flash a video card to force wire framing ...

#24Not to say this isn't a worrying practice, but it's unfortunately industry standard. Almost every mainstream fps game has intrusive software, to the point where you're expected to be thankful that it's not a rootkit (which is not unheard of).
Then there's CS:GO, whose developers refuse to use intrusive practices to counter cheating. And the game is ruined by rampant cheating. (Neither for nor against. Just saying.)

#25“ When you shut down Call of Duty: Warzone, the driver turns off.” is that really how drivers work?
Windows drivers can be loaded and unloaded dynamically, yes. It's also possible that they're using "shut down" semantically and not literally, in that the driver is loaded but inactive while the game isn't running.

#26“ When you shut down Call of Duty: Warzone, the driver turns off.” is that really how drivers work?
Yes. Drivers can be loaded and unloaded at will. It's a necessity for USB devices.
Heck, these days, even a GPU driver can be hot-swapped.

#27Microsoft should implement an Xbox mode for Windows that has these protection features for all games. It will probably require some virtualization and performance degradation but it's better than each game rolling out their own half assed drivers.
How about no? This will just lead these companies to implement anti-cheat to protect the "integrity" of their single player games (and their MTX) as well. Say goodbye to mods and other forms of benign game hacking (particularly hacks that fix games like Dark Souls).

#28Can anyone tell me why Fortnite doesn't seem to have as bad of a problem as CoD? My son plays both, but CoD really sucks. It is so obvious when someone is cheating.
I think Fortnite uses a projectile bullet model while Call of Duty is all hitscan, but I could be mistaken. It’s been years since I played a CoD game.

Yes, it's an impossible fight. Give up early and just detect the supernatural aim server-side or have a working report system.
Or increase the role of aim and reflex when determining rank.
Should also reduce smurfing somewhat - you'd only be able to dominate a match once with a given account.
