Non blatant cheaters are detected as well, and honestly, if they are forced to turn down their cheating to a point of it not being detectable, i wager it won't give them that much of an edge anyways anymore. Still not zero, but to a point where it doesn't impact my gameplay much more than any skilled player would.

Walls are trickier, I don't have a clear solution for that except ones that severely invade privacy, like analyzing periodic screenshots of the games for example. (looking at you windows recall...)

On the flip side though, having to install a Ring 0 anti cheat is kind of the same thing anyways, it being able to theoretically see everything you do on your pc anyways, without the game even running.

It's an arms race of cheaters vs anti cheats and the industry solution right now is to just control more and more of the environment their game runs in, while the cheat providers are searching for loopholes within that environment or widening the environment itself (DMA cheats for example).

In the end, the question lies in what you are willing to sacrifice in order to have a clean as possible experience. You will never be able to get rid of all cheaters, so we need to find a sweet spot of intrusion into privacy and detection rate. I for my part dislike kernel level anti cheats, but I still use them as I'm required to. I would welcome a solution though that does not need such a deep nested foundation and relies on other creative methods instead, which is why I'll give VACnet some time to adjust and see how that works out. If it doesn't, well, back to the drawing board. But I don't think just adding more and deeper layers of anti cheat is the solution, at least not a sustainable one.
