Because PUBG's recoil has a random component, "dumb" macros (which only move in one direction) can often pull too far down or fail to account for horizontal drift, making them less effective than manual control in many scenarios.

While these tools promise instant improvements in accuracy, they carry significant risks, including permanent account bans and the erosion of fair play. What is an RCS Macro?

Anti-cheat systems like BattlEye can detect macros by reading script files, identifying "superhuman" input speeds, or flagging perfectly identical mouse movements across multiple matches. [Dev Letter] Anti-Cheat System Improvements - NEWS - PUBG

Incorporating slight delays or "jitter" to try and bypass anti-cheat systems that look for "perfect" robotic inputs. How the Macro Works (Technical Overview)

The macro monitors for a specific trigger, usually a full pull of the fire button (Left Mouse Click or R2/RT).

Automated downward mouse movement tailored to specific guns like the M416 or Beryl M762.

As long as the trigger is held, the script executes "Move Mouse Y-axis" commands at a steady or accelerating rate.
