I spent my first decade of PC gaming wondering why my aim felt inconsistent. Some days I’d hit every flick shot. Other days I’d whiff completely at the same distance, with the same mouse, on the same map. Then a friend told me something that changed everything: I’d been playing with mouse acceleration enabled the entire time, and it had been silently sabotaging my muscle memory without me knowing.
If you’re trying to figure out how to fix mouse acceleration FPS aim problems, you’re in the right place. This guide walks through exactly what mouse acceleration is, why it wrecks competitive aim, how to diagnose whether it’s currently enabled on your system, and the exact steps to turn it off on Windows, macOS, and inside popular FPS games. I’ll also cover the 2-4 week adaptation period most players hit, because your aim will feel worse before it gets better.
By the end of this article, you’ll have a clean settings baseline, a verified off state, and a clear plan to rebuild your muscle memory from scratch. This isn’t theory. These are the exact changes I made and the timeline I followed to fix my own aim after a decade of inconsistent play.

What Is Mouse Acceleration and Why Is It Enabled by Default
Mouse acceleration is a cursor behavior built into Windows where the same physical hand movement produces different on-screen distances depending on how fast you move the mouse. Slow and steady travels a short distance. Flick your wrist hard and the same motion travels much farther across your screen.
The Windows feature is called Enhance Pointer Precision, and it’s been checked by default on every Windows install since the late 1990s. Most people never think to look at it. Microsoft designed it to help desktop users navigate large monitors with smaller physical movements, so casual users can throw their mouse across the screen without lifting it off the pad.
That design goal directly conflicts with FPS gaming. Competitive aim depends on a 1:1 relationship between your hand and the crosshair. The same wrist flick should land your crosshair in the same spot every single time, regardless of how fast you moved. When acceleration is on, that relationship breaks down because speed becomes a hidden variable in the equation.
Here’s how the underlying math actually works. Windows tracks how far the mouse sensor reports movement, then applies a speed-based multiplier on top of that distance. Faster movements get multiplied higher, slower ones stay near 1:1. The result is non-linear cursor behavior that’s impossible to internalize through repetition, because the outcome of any given movement depends on variables your hand can’t reliably control.
You’ll see this called cursor acceleration, pointer precision, or distance-based movement in different guides and forum posts. They’re all describing the same Windows feature, just with different naming conventions depending on the era and the source.
Modern Windows versions like 10 and 11 still ship with this enabled by default. If you bought a pre-built PC or performed a clean install and never opened the mouse settings, your cursor is almost certainly running accelerated right now. That’s the default state for the vast majority of PC gamers, which is why so many of them struggle with consistency without understanding why.
Why Mouse Acceleration Ruins Your Aim in FPS Games
Muscle memory is the foundation of every FPS aim skill worth developing. Your brain learns that “this much wrist rotation equals this much crosshair travel.” Repeat a movement a thousand times and your hand starts doing it automatically, which is how pro players land flick shots without consciously aiming or thinking about cursor distance.
Acceleration completely breaks that feedback loop. The same physical flick on Monday might travel 80 centimeters on screen. The same flick on Tuesday, performed slightly faster, might travel 120 centimeters. Your brain can’t build a reliable association between effort and outcome, so the skill ceiling stays artificially low no matter how much you practice.
This is why I see the same complaint over and over on Reddit’s FPSAimTrainer and GlobalOffensive boards. Players describe aim that feels random, where they nail a headshot in one round and miss the same swing in the next. Some have spent years blaming their mouse, their pad, their reflexes, or their chair when the actual culprit was a single Windows checkbox buried three menus deep.
One user on r/summonerschool posted that they’d played with enhance pointer precision enabled for almost 10 years before discovering it. They thought they were just bad at aiming. Within a month of disabling it, their ranked performance jumped two full tiers. This kind of story shows up constantly across competitive gaming communities.
Beyond muscle memory, acceleration sabotages three specific FPS skills that high-level play depends on. Micro-adjustments for tracking become guesswork because slow corrections don’t behave predictably. Flick shots lose precision because your fastest movements are also your least consistent. Crosshair placement at head height drifts because small pre-aim corrections get scaled differently based on speed rather than your actual intent.
Pro players overwhelmingly use raw input with acceleration disabled. CS2 pros, Valorant Champions Tour players, and Apex Legends Predators all run 1:1 mouse behavior across nearly every match they play. The competitive consensus is unanimous: raw input builds skill over time, while acceleration hides flaws and prevents real improvement.
There’s also a confidence factor that doesn’t get discussed as often. When you can’t predict where your crosshair will land, you develop hesitation. You stop taking the shots you should take because you don’t fully trust your hand. Disabling acceleration rebuilds that trust, because your input becomes reliable and your confidence in your own mechanics grows with every session.
How to Tell If Mouse Acceleration Is Currently On
Before changing anything, let’s verify whether acceleration is currently enabled on your system. The fastest test is the flick test, which takes about 30 seconds and requires no special software.
Open a large empty area on your desktop or a full-screen notepad. Move your mouse slowly across a small distance, say 5 centimeters. Note where the cursor lands. Now lift the mouse, return to the start, and flick it the same distance much faster. If the fast flick sends the cursor significantly farther than the slow movement, acceleration is on and active.
For a more precise check, you can also open Windows mouse settings directly. Press Win + I to open Settings, then search for “mouse settings” and click it. Look for Additional mouse settings on the right side. The Mouse Properties window that opens has a Pointer Options tab, and you’ll see Enhance pointer precision checked if acceleration is enabled.
Some games also have their own acceleration toggle buried in menus. In CS2, look under Settings, then Game, then look for any “mouse acceleration” slider. In Valorant, the setting lives under Settings, then Input. Most modern FPS titles default to raw input, but older or modded games sometimes override Windows behavior in ways you wouldn’t expect.
Another red flag is aim that feels inconsistent across sessions. If you can hit a target in the morning and miss the same swing at night, despite identical hardware and setup, acceleration is the most likely explanation. Combined with the flick test, this consistency check is usually enough to confirm the diagnosis.
There’s also a useful online tool called mouse-sensitivity.com that has a built-in acceleration detector. You move your mouse to match a target, and the site measures whether your slow and fast movements travel the same proportional distance. It’s a quick third-party verification if you want extra confidence before changing system settings.
How to Fix Mouse Acceleration: Step-by-Step Guide
Now for the actual fix. We’ll cover Windows 10 and 11, macOS, and the in-game settings for the three most popular competitive shooters. Follow these steps in order, and verify with the flick test after each platform change.
Disable Mouse Acceleration in Windows 10 and 11
Step 1. Press the Windows key and type “mouse settings”. Open the Mouse settings result that appears at the top of the search list.
Step 2. Click Additional mouse settings on the right side of the Mouse settings page. This opens the classic Mouse Properties dialog.
Step 3. In the Mouse Properties window that opens, click the Pointer Options tab at the top.
Step 4. Under the Motion section, find Enhance pointer precision and uncheck it. This single checkbox is responsible for Windows-side mouse acceleration across every application that doesn’t override it.
Step 5. Move the Select a pointer speed slider to the 6th notch from the left, which is the default neutral position. This is widely considered the optimal baseline for competitive FPS because it removes the Windows-level cursor scaling that some games inherit.
Step 6. Click Apply, then OK to save your changes and close the dialog.
Step 7. Repeat the flick test from the previous section to verify acceleration is now off. Both your slow and fast movements should travel roughly the same distance for the same physical motion.
Disable Mouse Acceleration in CS2 (Counter-Strike 2)
Step 1. Launch CS2 and open the settings menu from the gear icon in the top right.
Step 2. Navigate to Game, then locate the mouse section in the left sidebar.
Step 3. Confirm that Raw Input is enabled. This forces the game to read directly from your mouse hardware, bypassing any Windows-level processing that could reintroduce acceleration.
Step 4. Set Mouse Acceleration to 0 if the slider exists in your version of CS2. Some patches have moved or renamed this setting, so check the latest options if you don’t see it.
Step 5. Apply settings and test in the practice range with the flick test pattern. Move your crosshair to a wall, flick 180 degrees, and verify the crosshair lands in the same spot every time.
Disable Mouse Acceleration in Valorant
Step 1. Open Valorant and click the gear icon for settings in the top right corner.
Step 2. Click General, then find the input section in the settings list.
Step 3. Toggle Raw Input Buffering to On. Valorant uses this terminology instead of “raw input” but it does the same thing, ensuring the game reads directly from your mouse sensor.
Step 4. Verify your sensitivity and scoped sensitivity are set to your intended values. Scoped sensitivity is its own separate setting in Valorant and works for Operator and Marshal.
Step 5. Save settings and verify in a deathmatch or the practice range. Test both hipfire and scoped movement to confirm consistency.
Disable Mouse Acceleration in Apex Legends
Step 1. Launch Apex Legends and open settings from the main menu.
Step 2. Click Mouse / Keyboard in the settings sidebar.
Step 3. Look for the Mouse Acceleration slider and set it to 0. Apex has this slider in newer patches even though most games rely on raw input now.
Step 4. Set your Mouse Sensitivity to your intended value based on your target eDPI. Apex has separate sliders for general sensitivity, ADS sensitivity, and per-zoom levels.
Step 5. Save and test in the Firing Range. Move to a fixed point, flick 180 degrees, and verify the crosshair lands on the same spot every time.
Disable Mouse Acceleration on macOS
Step 1. Click the Apple menu and open System Settings.
Step 2. Navigate to Mouse in the sidebar.
Step 3. Turn off Natural scrolling if it’s interfering with your aim movement style or causing reverse-direction issues during tracking.
Step 4. Use a third-party tool like SteerMouse or Cursorcerer for finer control over pointer speed and acceleration, since macOS has limited built-in options for disabling acceleration entirely.
Step 5. Test in-game. macOS competitive FPS players usually need to use raw input tools because the OS itself handles cursor movement differently than Windows, and games don’t always have OS-level overrides.
Optimal DPI and Sensitivity Settings for FPS Games
Disabling acceleration is only the first half of the fix. You also need a proper DPI and sensitivity baseline so your wrist can build consistent muscle memory over the coming weeks.
Most professional FPS players run between 400 and 800 DPI on their mouse. This range gives you enough precision for micro-adjustments without requiring giant arm sweeps for turns. Anything above 1600 DPI tends to introduce sensor noise and pixel skipping on most mice, and it forces your hand into unnatural movements that limit your precision ceiling.
Your eDPI, or effective DPI, is the number that actually determines how fast your crosshair moves across the screen. The formula is simple: multiply your mouse DPI by your in-game sensitivity. So a 800 DPI mouse with 0.5 in-game sensitivity gives you an eDPI of 400, while a 400 DPI mouse with 1.0 in-game sensitivity also gives you 400.
Most competitive players land in the 200 to 800 eDPI range for tactical shooters. CS2 and Valorant pros tend toward the lower end, often between 600 and 1000, while Apex Legends and Overwatch pros sometimes run higher at 800 to 1200 because the games involve larger map movement and faster engagements. Pick a value in these ranges and stick with it.
Once you’ve picked a DPI and sensitivity, write them down on a sticky note or save them in a notepad file. Don’t change them for at least two weeks. Constant sensitivity tweaking is one of the most common reasons players feel stuck. Your hand needs repetition at the same numbers to build the neural pathways that translate into reliable aim under pressure.
Polling rate is the final hardware setting worth understanding. Your mouse reports its position to your PC at fixed intervals measured in Hertz. Most gaming mice default to 1000Hz, which means the cursor position updates every 1 millisecond. Higher rates like 4000Hz or 8000Hz exist but don’t translate to better aim for most players, and they can introduce instability on some systems. 1000Hz is the safe standard.
Mousepad size also matters more than people think. If you’re running a sensitivity that requires large arm sweeps for 180-degree turns, you need a pad large enough to support that motion without lifting. A 40 by 45 centimeter pad is the standard size for most competitive players, with extended 90 centimeter options available for low-sensitivity players who want maximum arm travel.
Game-Specific Settings to Check (CS2, Valorant, Apex)
Beyond the system-level fix, each major FPS has a few in-game toggles that can either help or hurt your raw input setup. These are easy to miss and they re-enable behavior you’ve already disabled at the OS level.
CS2: Make sure Raw Input is enabled and Mouse Acceleration is at 0. Also confirm that Zoom Sensitivity Match is set the way you want for scoped weapons. Snipers in CS2 use a separate sensitivity multiplier, and inconsistent values here create hidden variability between hipfire and scoped fights.
Valorant: Enable Raw Input Buffering and double-check that your scoped sensitivity feels consistent across all weapons. Valorant’s Operator and Marshal both use scoped sensitivity, so an inconsistent value here creates the same variability issues as CS2’s zoom settings.
Apex Legends: Set Mouse Acceleration to 0 and verify your Mouse Sensitivity matches your target eDPI. Apex has separate sliders for general sensitivity, ADS sensitivity, and per-zoom levels, so test each one and confirm they all feel consistent with your locked Windows settings.
For all three games, run a quick test in their respective practice ranges after changing settings. Move your crosshair to a fixed point, flick 180 degrees, and check that the crosshair lands in the same spot every time. This is the in-game version of the flick test, and it confirms that the game’s mouse handling matches your OS-level config.
The 2-4 Week Adaptation Period After Disabling Acceleration
This is where most players give up, and it’s the section I wish someone had written for me when I made the switch. Your aim will get worse before it gets better. That is normal, expected, and temporary, and the people who push through it are the ones who actually see improvement.
When you disable acceleration, you’re essentially resetting years of muscle memory built on inconsistent feedback. Your hand has been learning a non-linear movement system, and now you’re asking it to learn a linear one. The first one to two weeks feel genuinely frustrating. You’ll miss shots you used to hit. You’ll feel like you got worse overnight, and you’ll be tempted to turn acceleration back on.
Stick with it. The community consensus from r/FPSAimTrainer and other competitive forums is that the adaptation period runs 2 to 4 weeks for most players. Some take longer, especially if they’ve been using acceleration for years or have thousands of hours with the old settings. By week 3, the linear movement starts feeling natural. By week 4, most players report their aim is meaningfully better than it ever was with acceleration on.
To shorten the adaptation period, run 15 to 30 minutes of aim training daily using tools like KovaaK’s or Aim Lab. Stick to the same scenarios for at least a week before switching. The point isn’t to chase scores or unlock new content. The point is to repeat the same physical movements thousands of times at your new sensitivity so your brain can build the new neural pathways.
Don’t switch sensitivity during this period, even if you’re tempted. The whole point of disabling acceleration is consistency. Sliding your sensitivity around defeats the purpose, and every time you change a value, your adaptation timeline restarts. Pick a value, lock it, and train through the awkward phase.
You can also warm up with a quick flick test on your desktop before every play session. It takes 30 seconds and confirms your settings are still correct, especially after Windows updates that occasionally reset defaults. Building this habit keeps your training on track and prevents accidental regressions.
Common Mistakes to Avoid
The single biggest mistake I see is changing too many settings at once. Players disable acceleration, change DPI, switch mouse pads, and adjust in-game sensitivity all in the same week, then can’t tell which change helped or hurt. Change one variable at a time and give it at least a week before adjusting the next one.
Second, don’t assume your aim trainer scores will reflect in-game performance. KovaaK’s scores are useful for measuring progress, but the jump to actual FPS matches requires additional skills like crosshair placement, game sense, and positioning. Use the trainer for repetition and consistency, not as a substitute for real game time.
Third, watch for software that re-enables acceleration. Some RGB mouse software, driver suites, and gaming center applications will reapply their own cursor smoothing or acceleration settings when they restart. Check your mouse’s official software and disable any pointer behavior modifiers, especially after driver updates.
Fourth, verify periodically. Run the flick test from earlier every few weeks. After Windows updates, mouse driver updates, or major game patches, double-check that enhance pointer precision is still unchecked. Updates occasionally reset default settings, and a single accidental re-enable undoes weeks of adaptation.
Fifth, don’t compare your sensitivity to pro players without context. TenZ plays at 800 DPI and 0.35 in-game, giving him an eDPI of 280. s1mple runs 400 DPI and 2.0 for an eDPI of 800. Both are excellent at their respective games. Your hand size, mouse grip style, and mousepad size all affect what feels right. Use pro values as a starting point, then adjust within the recommended range for your playstyle.
Sixth, don’t fall for the trap of constantly buying new gear. The honest truth is that 90% of aim problems come from settings and practice, not hardware. A $30 mouse with proper settings and training will outperform a $150 mouse with acceleration enabled and inconsistent practice. Fix your settings first, then consider upgrades only after you’ve plateaued.
Frequently Asked Questions
Why is mouse acceleration bad for FPS?
Mouse acceleration breaks the 1:1 relationship between physical mouse movement and cursor travel because it scales distance based on speed. This makes muscle memory unreliable, because the same hand movement produces different on-screen results depending on how fast you move. Without consistent feedback, your brain can’t build accurate aim patterns, which is why competitive FPS players almost universally disable it.
How to fix aim acceleration?
Open Windows Settings, search for mouse settings, click Additional mouse settings, go to the Pointer Options tab, and uncheck Enhance pointer precision. Also set the pointer speed slider to the 6th notch. In games like CS2 and Valorant, enable Raw Input or Raw Input Buffering. In Apex Legends, set the Mouse Acceleration slider to 0. Then verify with the flick test described in this guide.
Is 1600 dpi too high for FPS?
1600 DPI is workable but not ideal for most FPS players. The competitive sweet spot sits between 400 and 800 DPI because it gives you finer control over micro-adjustments without requiring massive arm sweeps. Higher DPI settings can introduce sensor noise on some mice and reduce the usable precision in your wrist movements. 1600 works if you prefer a higher eDPI target and your mouse sensor handles it cleanly, but most pros stay lower.
Why am I suddenly so bad at aiming?
Sudden aim loss after disabling mouse acceleration is the expected adaptation phase. Your hand spent years learning a non-linear movement system, and switching to 1:1 raw input requires your brain to rebuild muscle memory from scratch. The dip usually lasts 2 to 4 weeks depending on how long you used acceleration. Daily aim training with KovaaK’s or Aim Lab at your locked sensitivity speeds up the recovery.
Final Thoughts
Fixing mouse acceleration is the single highest-impact change most FPS players can make to their setup. Uncheck enhance pointer precision, set pointer speed to the 6th notch, enable raw input in your games, lock your DPI and sensitivity, and commit to the 2-4 week adaptation period. The first two weeks will feel rough, but by the end of month one your aim will be more consistent than it ever was with acceleration enabled.
