I’ve worked in esports for a bit and there’s definitely cheats out there that pros use. When utilised well you won’t even notice when directly spectating or when the player is streaming. They’re designed to help extremely good players just that little bit extra needed to become a top-tier player.
Those “pro-grade” cheats don’t come cheap though. I’ve heard figures in the 400-600/month range multiple times. These would also work on the special tournament clients used by professional players.
