I saw someone in an earlier game doing a 90 degree snap turn while playing (left and right) and I was wondering if that's considered cheating or not. If not, how does one do it?

if it snaped to the player then it's most likely aimbot.

Even though cheat reporting is not allowed here on FourDeltaOne, yes that person was most likely hacking with an aimbot.

Not quite what I meant. I'm not reporting (hence the absence of a name) and it wasn't a snap to a player, just a general "turn 90 degrees quickly/precisely". He was good, but he definitely wasn't aimbotting.

Okay, well yeah I can do that kind of aiming easily, you just have to know how to work a mouse properly.

So... mouse macro?

Umm no... using your hand and wrist...

High sensitive mouse + Higher sensitivity + wrist snap = 90 degree turns with ease.

May be yawspeed?
