The DPI Myth
Every gaming mouse box screams a giant DPI number — 16,000, 26,000, more. It's the most successful piece of pointless marketing in PC hardware, because almost nobody who aims seriously runs anywhere near those values. The overwhelming majority of FPS players set their mouse between 400 and 1600 DPI and pair it with an in-game sensitivity that produces the overall speed they want.
Why doesn't a huge DPI help? Because DPI only determines how the total sensitivity is split between hardware and software, not what your hand does. What your hand experiences is the combined result — best measured as cm/360, which we break down in our mouse sensitivity guide. Cranking DPI to 16,000 and dropping in-game sens to compensate lands you in the same place, with the added annoyance that your desktop cursor becomes nearly unusable.
There's a reasonable technical argument for moderately higher DPI (800–1600 rather than 400): the sensor reports finer movement increments, so very slow micro-adjustments render slightly more smoothly. It's a subtle effect, and plenty of top players still use 400 DPI without issue. Pick a value in the standard range, rebuild your in-game sens around it, and never think about it again.
Polling Rate: An Honest Take
Polling rate is how often your mouse reports its position to the PC, in hertz. Here the marketing contains a kernel of truth — and then overshoots it.
The jump from 125Hz to 1000Hz is real and noticeable. At 125Hz the mouse reports every 8 milliseconds; at 1000Hz, every 1 millisecond. Fast swipes feel visibly smoother and input lands with less delay. If your mouse is somehow stuck at 125Hz, fixing that is one of the few settings changes you may genuinely feel the same day.
Beyond 1000Hz — the 2000, 4000, and 8000Hz modes on newer mice — you're deep into diminishing returns. The theoretical latency saving from 1000Hz to 8000Hz is under a millisecond. Some players on high-refresh monitors report marginally smoother cursor motion; blind tests rarely show anyone reliably detecting it, and the higher rates cost CPU and, on wireless mice, battery. Run 1000Hz. If your mouse offers more and you're curious, try it — just don't pay extra for it.
Fix Windows Before You Fix Anything Else
Two Windows settings silently sabotage more aim than any hardware choice.
Turn off Enhance Pointer Precision
Despite the reassuring name, "Enhance Pointer Precision" is mouse acceleration: it scales cursor distance based on how fast you move the mouse. The same 5cm swipe travels a different distance depending on how quickly you performed it — which destroys the fixed hand-distance-to-crosshair-distance mapping your muscle memory depends on. Open Mouse settings, then Additional mouse settings, then the Pointer Options tab, and uncheck it.
Leave the pointer speed slider at 6/11
The Windows pointer speed slider has 11 notches, and the middle notch — 6 of 11 — is the only position where Windows passes mouse input through 1:1. Other notches multiply or skip counts, which distorts movement in any application that reads the Windows cursor rather than raw input. Set it to the middle and leave it.
These two fixes matter most for desktop apps and older games. Modern shooters with raw input bypass both settings — but you want your OS baseline clean regardless, and browser-based trainers benefit too, as explained next.
Raw Input, and How AimBetween Handles It
Raw input means the game reads movement data directly from the mouse instead of taking the Windows cursor position, ignoring OS-level acceleration and scaling entirely. Every serious FPS offers it, and it should essentially always be on — it guarantees the game sees exactly what your hand did.
AimBetween applies the same principle in the browser: when a round starts, the trainer captures your mouse with the Pointer Lock API using raw, unaccelerated input, so OS pointer acceleration is taken out of the loop. Your crosshair responds to physical mouse movement the same way an in-game crosshair with raw input does — which is exactly what you want from a practice tool, because movements you groove in the trainer only transfer to your game if both are reading your hand the same way. Try a round of Gridshot after unchecking Enhance Pointer Precision and you'll feel how consistent 1:1 input is.
Mousepad and Grip Tape: A Brief Word
Your pad is part of your input chain, and it matters more than most spec-sheet items. Three things to get right:
- Size. If you play at a lower sensitivity (a longer cm/360), a small pad physically prevents full swipes. A large desk pad removes the constraint entirely and costs little.
- Consistency. A worn, shiny, or dirty patch in your pad's center changes friction mid-swipe. Pads are consumables; clean them, and replace them when the surface glazes.
- Speed vs control. Faster (slicker) pads favor big flicks; slower (cloth, textured) pads favor controlled stops and tracking. Neither is better — pick one feel and stay with it, for the same consistency reasons that apply to sensitivity.
Grip tape — textured adhesive strips for the mouse's sides and buttons — is a cheap fix if sweaty hands make your grip shift during play. A grip that slips mid-flick introduces exactly the kind of inconsistency that's hard to diagnose; if that sounds familiar, our guide on grip styles covers how to spot grip-related problems.
Wired vs Wireless in the Current Generation
Five-plus years ago, "wireless adds lag" was solid advice. It no longer is. Modern gaming-grade wireless mice using dedicated 2.4GHz dongles perform at parity with wired mice — latency differences are down in the sub-millisecond range, and wireless models are now standard equipment at the highest levels of competitive FPS. The absence of cable drag is a genuine ergonomic win.
Two honest caveats. Bluetooth is not gaming wireless — it polls slowly and adds real latency, so always use the dongle. And wireless means battery management; a mouse that dies mid-session is worse than any cable. If you'd rather not think about charging, a light wired mouse with a flexible cable (or a cable bungee) gives up essentially nothing.
What NOT to Waste Money On
- Max DPI specs. You will never use 26,000 DPI. Any sensor in a current gaming mouse is flawless at the 400–1600 range you'll actually run.
- 8000Hz polling as a selling point. Nice if included, not worth paying a premium over a 1000Hz mouse.
- RGB and software suites. Zero effect on aim. If anything, background peripheral software occasionally causes stutters — install it once to set DPI and polling, then let it go.
- "Esports edition" markups. A pro's name on the box changes nothing about the sensor inside it.
- Constant upgrades. A new mouse resets your feel for shape and weight. The player who has aimed on the same decent mouse for two years beats the one who swaps hardware every quarter.
Here's the uncomfortable truth all of this points to: settings and gear are maybe five percent of aim. Once acceleration is off, polling is at 1000Hz, and your sens is stable, every further gain comes from training — starting with fundamentals like crosshair placement, which costs nothing and pays more than any mouse ever will.
Settings sorted? Then there's nothing left to blame. Put them to work with a few rounds in the trainer — it's free and runs in your browser.
