According to experts on kernel level anticheat, two things are abundantly clear: 1) It's not perfect and 2) It's not going anywhere

Like Denuvo DRM or shader compilation stutter, «kernel level anticheat» is one of the most high profile issues dogging PC gaming in recent years. The default position of most gamers is that it's a crutch used by «lazy devs», it ruins performance, and could even compromise security. However, after reading games marketing veteran Ryan K. Rigney's Push to Talk report, in which he interviews multiple professional anticheat experts, it's clear that the tech's here to stay regardless.

For the uninitiated, what it means when anticheat is operating at kernel level is that it's running at the deepest, most authoritative layer of your operating system. Developers appreciate that level of control in detecting and shutting down cheat programs, pre-empting them with a maximum level of system authority. Many consumers understandably take issue with relinquishing that level of control to a third party. 

For one instructive example of the power and invasiveness of these tools, look no further than the high profile Destiny raider who lost his account after the game's anticheat flagged a cheat engine program he had installed for the single player Shogun: Total War 2 and never used on Bungie's FPS-MMO.

That feeling of intrusion can often result in a tense, sometimes hysterical tone to conversations about the software: review bombs, threats, more «lazy dev» discourse, etc. The experts that Rigney interviewed are clearly well aware of how unpopular kernel level anticheat is with some players. His Odyssey Interactive colleague, software engineer Paul Chamberlain, calls it «a cursed field to work in.»

Riot Games head of anticheat, Phillip Koskinas, argues that developers essentially have to be secretive about how their anticheat works in order to retain every advantage against cheat developers, who are themselves constantly searching for vulnerabilities. That secrecy, though understandable in an arms race against cheats, doesn't help the tech's reputation among gamers.

I'm less worried
