By the point of ‘superhuman’ gameplay, it’s less about physical reactions and more about mental foresight or gamesense. Ducking, sliding, bhopping and any tech involved to navigate… planning how your opponent will move around your positioning in relation to their own objectives… Individual players have quirks by this point that can be discovered and exploited, and you are both playing a game to discover & exploit; Deceive & switch-up.
When someone is exclusively reacting to you perfectly rather than incorporating the above, you know. It’s wildly demotivating because now we’re not playing this high-skill game, we’re playing a game of endurance since they always know player locations and will almost always get the first shot… The only two winning moves is you leave or the hacker leaves. It’s a waste of everyone’s time just for some narcissist to feel good (I can say that, I used to do it so I get the power thrill).
It sucks and anyone who’s pushed their competitive gameplay to the edge will recognize a hacker when they see one. So yes, players can tell the difference (including chess players!!), it’s the anti-cheat that can’t. Kind-of like how that one MS guy discovered a backdoor due to a 500ms delay, but a virus protector sees everything hunky-dory.

Also, no, matchmaker will not separate these people appropriately. The cheaters will smurf just to dunk on lower-skill players. You can buy game-keys on russian websites for dirt cheap, so it’s very worth it if you have the $$$ to burn. Path of least resistance to feeling power.
