Cheating is a meat space problem and there is no technical solution to it. Thats why in tournaments there are referees standing behind the players. Ultimately it comes down to checking if metrics like reaction speed are humanly possible, but a rootkit is not really needed for that.

Cheating is an arms race - the number of people who are willing to run a second computer with DMA connected to a single machine is vastly smaller than the number of people who are wiling to download a dodgy file from the internet and run it.

If it was that easy, cheating would be a solved problem. An awful lot of play is "I know the reload time is 0.75s, so they're going to appear when they've reloaded" - that's way beyond human reaction time. And that's at "mid level" play - at gold/sliver levels in league of legends knowing cooldowns is considered base knowledge. At higher levels of play, _all_ of your players are statistical outliers.
