“ When you shut down Call of Duty: Warzone, the driver turns off.” is that really how drivers work?

Huh...that seems a bit excessive.

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?

You wouldn't. But it's my computer and it's supposed to serve me, not you.

It's cheating really that big of a deal? How do they try to stop it now? Do they really need a kernel driver?

Next will be cheats that run in hardware themselves ... I wonder if it's possible to flash a video card to force wire framing ...

From what I understand there are already cheats that work at the hardware level (read video output, modify mouse input) with all software running on another machine.

Probably going to make it proton-incompatible, I'm guessing.

There'll be patches to enable this for Linux soon enough.

Microsoft 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.

Ironically, in XBox OS I'm pretty sure there's not a big distinction between usermode and kernel mode.

So the endgame would be a type-1 anti-cheat hypervisor I guess?

I mean, this is already happening! Have a Google for "Hardware CS:GO aimbot" and there are some crazy things people are doing to cheat in video games. Stuff that attaches to the CPU, ones that attach to the mouse to fake input that way, it's really quite ingenious. The market for these devices is enormous.

I guess radar cheats where the ethernet cable to split to a second computer could also be considered a hardware cheat, since it's running between an airgap.

Can 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.

Definitely already exists. I've seen external aimbots that monitor what's on screen and input specific keyboard/mouse commands.

Incredibly difficult to detect, you basically need to model the way users behave differently from bots... but at the high end of competitive play people tend to approach more bot-like behaviors.
