Game Sensitivity
Tells hzRecoil your CS2 sensitivity so the compensation is scaled correctly.
Imagine pushing the mouse 1 cm. With high sensitivity the crosshair travels far; with low, barely at all. hzRecoil needs to know this 'exchange rate' to move the crosshair by exactly the right amount and cancel the recoil, not too little, not too much.
Every pattern point is multiplied by a scale factor of 2.45 / sensitivity before becoming mouse movement. At the default sensitivity of 1.08, the factor is ~2.27. If this value doesn't match your in-game sens, the whole pattern is mis-scaled. The app also auto-detects sensitivity by reading the CS2 config when you switch Steam accounts.
Higher than your real sens → the macro pulls too much (overcompensates) and the crosshair drops past the target. Lower → it pulls too little and recoil leaks upward. The right value isn't 'high' or 'low': it's identical to the game's.
Keep it equal to your CS2 sensitivity (the sensitivity cvar). Changed your in-game sens? Update it here too, or trust auto-detection.
It's the foundation of everything: if it's wrong, no amount of precision or humanization tuning will fix the scale. Get this right first.
