Sensitivity: how to pick one and stop changing it

You had a bad session. You searched for a pro's settings, changed your sensitivity, and the next session felt worse. So you changed it again. Six weeks later your aim is worse than when you started and you are not sure what your sensitivity even is any more.

Sensitivity changes feel like progress because they change something. What they actually do is throw away the muscle memory you had built and start you over. There is no sensitivity that fixes crosshair placement, movement or decision-making. There is a sensitivity that lets you build muscle memory, and the main thing it needs to be is the same one as last week.

Aim is a learned mapping between what you see and how far you move your hand. That mapping takes weeks to build and seconds to break. Every change, even a small one, means the flicks you had learned now land slightly off, and your brain has to relearn the whole map.

Consistency is the actual skill. A player who has used the same sensitivity for a year has a hand that knows what a 90-degree turn feels like without checking. That player can put their attention on the game. The player who changed last week is still half-thinking about their hand.

1. Measure in eDPI, not "sensitivity". Mouse DPI multiplied by in-game sensitivity. 800 DPI at 1.0 is 800 eDPI, and so is 400 DPI at 2.0. This is the number that lets you compare settings across mice and across people. Write yours down now.
2. Know the range, then pick a point in it. Most high-level tactical shooter players sit in a moderate band, roughly 600 to 1,000 eDPI in CS2 or its equivalent in your game. Low enough for precise micro-adjustment, high enough to turn. If you are far outside that band, consider moving in. If you are inside it, stop moving.
3. Match your desk. If your desk lets you make a long arm swing, a lower sensitivity works. If you are cramped and aiming from the wrist, go a little higher. The setting should suit your space, not a pro who has a different desk.
4. Convert across games, do not re-guess. If you play more than one shooter, use a converter to carry the same 360-degree distance across titles. Your hand should feel the same in every game, so that practice in one carries over.
5. Lock it for eight weeks. Pick the number and do not touch it, even after bad sessions. Especially after bad sessions. Bad sessions are almost never the sensitivity.
6. Only change it for a reason you can name. A new mouse. A new desk. A conversion you got wrong. "I lost three games" is not a reason. If you do change, change once, small, and lock it again for eight weeks.

Your aim will feel wrong for a few days after you commit to a setting. That is the muscle memory rebuilding. Push through it once and never do it again.
