ADS sensitivity — the setting most players get wrong
You've trained your hipfire aim for hundreds of hours. Then you ADS and the camera flies past every target. Your hipfire and scoped aim feel like they belong to two different players. That's almost always the ADS sensitivity coefficient — a single setting that decides how the same mouse motion translates when your FOV shrinks.
Why ADS needs a different sens
When you aim down sights, your effective FOV drops dramatically — a 103° hipfire might become a 55° iron-sight or a 25° scope view. If your sens stayed the same, the camera would rotate the same degrees per mouse count, but on-screen targets are now much bigger relative to the viewport — you'd over-aim by a huge factor.
Every modern FPS handles this with an ADS sensitivity multiplier (sometimes called "Coefficient", "Aiming Mode", "Per-Optic Sens", or "Zoom Sens"). The default is almost always sane; the wrong choice is silently catastrophic.
The three modes that exist
1. Relative / 1.0 / Legacy (the default for almost everyone)
The cursor stays on the same world point when you ADS. If your crosshair was on a target before zooming in, it's on the same target after. This is the natural behavior; it's what your hipfire muscle memory expects.
Names: Apex calls it "Coefficient: Legacy". COD calls it "Relative". Valorant uses "Scoped Sensitivity Multiplier 1.0". CS2 uses "Zoom Sensitivity 1.0". They all mean the same thing.
2. Affected by FOV / 0.0
The camera rotates the same degrees per mouse count regardless of FOV — meaning when you ADS into a smaller FOV, on-screen rotation feels much faster. Almost no one wants this. Avoid.
3. Custom multiplier (0.6 – 1.5)
Some pros tweak this for specific weapons. A flick-style sniper might use a coefficient under 1.0 (smaller scope = even smaller relative motion, easier to land headshots on minor adjustments). A hipfire-heavy player might use over 1.0 to keep ADS feeling snappy. Default to 1.0 unless you've trained hours on per-weapon flicks.
What to set, by game
| Game | Setting name | Recommended |
|---|---|---|
| Apex Legends | Mouse Sensitivity Coefficient | Legacy |
| COD MW / Warzone | ADS Sens Multiplier | Relative |
| Valorant | Scoped Sensitivity Multiplier | 1.0 |
| CS2 | Zoom Sensitivity | 1.0 |
| Overwatch 2 | Aim Smoothing | Off (separate but related) |
| Rainbow Six | ADS Sens Multiplier (per zoom) | 1.0× across all |
How pros tune ADS for sniping
Some Valorant Operator users set Scoped Multiplier to 0.85-0.9 because the long-zoom scope at 1.0 feels too jittery on flicks. Apex Kraber/Charge Rifle users sometimes do the same with per-optic ADS multipliers. The math: smaller multiplier = smaller cursor motion per mouse count = easier micro-adjustments at long range.
Test before committing. Hop into deathmatch / range, fire off 50 long-range shots at the default, then 50 at -0.1 multiplier. If you hit more headshots at the lower value, keep it.
A word on Mouse Acceleration
Some games have a hidden "Mouse Acceleration" or "Smoothing" toggle. Always off. We covered Windows-level acceleration separately in our Windows pointer precision trap post — both should be off, both for the same reason.
Verify your ADS sens with our tool
Our ADS / Hipfire Sync calculator takes your hipfire FOV, ADS FOV, hipfire sens, and coefficient, and shows you the resulting ADS sensitivity number. Useful for confirming a custom multiplier matches what your hand expects before committing to a long training session.
