Best Modern Warfare 4 Mouse and Keyboard Settings for FPS and Aim
Published
On this page
Modern Warfare 4 rewards a mouse setup that is fast enough for close-range flicks but consistent enough to hold recoil at range — and that comes down to 800 DPI, an in-game sensitivity around 6–7, mouse acceleration and smoothing off, and a 1000 Hz polling rate. Dial those in and your aim stops fighting you.
This is the keyboard-and-mouse companion to our best Modern Warfare 4 controller settings guide. Everything below lives in Settings → Mouse & Keyboard and Settings → Input unless noted. Change one setting at a time, then play a few real matches before adjusting again — aim is muscle memory, and swapping five things at once tells you nothing.

| Mouse Sensitivity (in-game) | 6.0–7.0 |
| ADS Sensitivity Multiplier | 1.00 |
| ADS Sens. Multiplier type | Relative |

DPI and sensitivity: aim for cm per 360°
The number that actually matters is not DPI or in-game sensitivity alone — it is effective DPI (eDPI), which is DPI × in-game sensitivity, and how many centimeters of mousepad you need for a full 360° turn.
- 800 DPI × 6.5 sensitivity puts most players around 32–36 cm/360°, the competitive sweet spot for Modern Warfare 4.
- Go higher cm/360° (lower sens) for steadier long-range tracking and easier recoil control.
- Go lower cm/360° (higher sens) if you struggle to turn on players flanking you up close.
Keep DPI at 800 and only move the in-game slider. A clean hardware DPI value keeps your sensitivity portable between MW4, Warzone, and every other shooter, so your muscle memory carries over. For the full method, see how to find your perfect sensitivity (eDPI) and our best mouse DPI and sensitivity for FPS guide.
Turn off everything that breaks 1:1 aim
Consistency beats raw speed. Three settings quietly add variability between identical flicks — turn them all off:
- Mouse Acceleration → Off. Acceleration makes a fast flick travel farther than a slow one at the same distance, so the same wrist motion lands differently every time. Also disable it in Windows — see how to turn off mouse acceleration for gaming.
- Mouse Smoothing / Filtering → 0. Smoothing averages your recent movements to hide low-quality sensor data, at the cost of a slight, unpredictable lag between hand and crosshair.
- Weapon Input Response Curve → Instant (or Standard). This keeps the crosshair reacting immediately to input instead of easing in.
ADS multiplier and monitor distance coefficient
- ADS Sensitivity Multiplier → 1.00, Relative. Relative scales your aim-down-sights speed to match your hip sensitivity feel across every zoom level, which keeps close-range and mid-range aim coherent. Only drop to ~0.90 if you consistently overshoot while aiming.
- Monitor Distance Coefficient → 1.33. This controls how your ADS sensitivity is measured across different scopes and FOVs. 1.33 keeps the on-screen rotation consistent between optics, so a low-zoom red dot and a 3x scope feel like the same aim — the most transferable choice.
Polling rate: 1000 Hz is the smart default
Set your mouse to 1000 Hz in its software (Logitech G Hub, Razer Synapse, etc.). At 1000 Hz the mouse reports its position every 1 ms, which is smooth and imperceptibly different from higher rates in real gunfights.
Modern mice offer 4000 Hz and 8000 Hz modes, but those increase CPU overhead and can cost you frames on mid-range systems — a real problem in a CPU-heavy shooter like MW4. Only use them if your FPS and 1% lows stay rock-steady. More on the trade-off in mouse polling rate explained.
Best Modern Warfare 4 keybinds
Keybinds are personal, but a few competitive defaults consistently outperform the stock layout:
| Action | Recommended bind |
|---|---|
| Jump | Spacebar |
| Crouch / Slide | C (toggle Crouch) + Left Ctrl (Slide) |
| Prone | X or mouse side button |
| Sprint / Tactical Sprint | Left Shift (Hold) |
| Melee / Finisher | Mouse Button 4 (side) |
| Interact / Reload | separate them — F for interact, R for reload |
| Ping | Mouse Button 5 (side) |
- Split Interact and Reload. Sharing one key causes accidental reloads when you try to pick up a weapon mid-fight. Bind Interact to F and keep Reload on R.
- Move melee off the mouse wheel to a side button so you never whiff a knife because the wheel scrolled.
- Bind Ping to a side button so you can call out enemies without lifting a movement finger.
Cut input lag so your settings actually land
Perfect sensitivity still feels sluggish if the frame you are aiming at is old. Lock these in alongside your mouse settings:
- Cap your frame rate a few FPS below your monitor’s refresh rate to stabilize latency — see best FPS cap for low latency and our Modern Warfare 4 lowest input lag settings.
- Enable NVIDIA Reflex (or the AMD equivalent) in MW4’s graphics menu to drain the render queue.
- Run a lower timer resolution at the Windows level for steadier frame pacing — the core of our timer resolution guide.

Frequently asked questions
What are the best mouse and keyboard settings for Modern Warfare 4?
Use 800 DPI, an in-game sensitivity of 6.0 to 7.0, ADS Sensitivity Multiplier at 1.00 (Relative), Mouse Acceleration off, and Mouse Smoothing / Filtering off. That lands most players near 30–40 cm per 360° turn, which is fast enough for close-range gunfights but stable enough to hold long-range aim. Set your polling rate to 1000 Hz and tune the in-game sensitivity, not DPI, from there.
What DPI and sensitivity should I use in MW4?
800 DPI with an in-game sensitivity around 6–7 is the standard competitive starting point in Modern Warfare 4. Lower combined sensitivity (higher cm/360°) helps ranged tracking and recoil control; higher helps fast 180° turns. Change one variable at a time — pick 800 DPI and adjust only the in-game slider so your muscle memory transfers between titles.
Should I turn off mouse acceleration and smoothing in Modern Warfare 4?
Yes. Turn Mouse Acceleration off and set Mouse Smoothing / Mouse Filtering to 0 in Modern Warfare 4. Both break the 1:1 link between hand movement and crosshair movement, so the same flick lands in a slightly different spot each time. Disabling them makes your aim consistent and repeatable, which is what builds reliable muscle memory.
What is the best ADS sensitivity multiplier for MW4?
1.00 with ADS Sensitivity Multiplier set to Relative is the best default for Modern Warfare 4. Relative keeps your aim-down-sights speed proportional to your hip sensitivity, so the transition feels natural. Drop it toward 0.90 only if you overshoot targets while scoped; sniper-heavy players sometimes lower the high-zoom multiplier specifically.
What mouse polling rate should I use in Modern Warfare 4?
1000 Hz is the right polling rate for Modern Warfare 4 on almost every PC — it reports mouse position once per millisecond with negligible CPU cost. Higher rates like 4000 or 8000 Hz shave a fraction of a millisecond more but can raise CPU usage and cost you frames on mid-range systems, so only use them if your FPS stays stable.
