1. Why Does Your Mouse Feel Too Slow?

When moving your mouse across a 1440p or 4K monitor requires repeatedly picking up and resetting your mouse, your setup is constrained by low optical sensor resolution (e.g. 400 DPI), OS software decimation, or physical tracking friction.

2. Step 1: Increase Your Hardware DPI

Press the DPI button on your mouse to switch to a higher stage, or open companion software (Logitech G HUB, Razer Synapse) and increase your resolution from 400 or 800 DPI up to 1200 or 1600 DPI.

3. Step 2: Clean the Optical Lens & Skates

Turn your mouse over and inspect the sensor cavity. Use a can of compressed air or a soft cotton swab to clear any dust or lint. If the mouse PTFE feet (skates) are scratched or worn down to the plastic shell, replace them with aftermarket pure PTFE skates.

4. Step 3: Verify Windows Pointer Speed

In Windows main.cpl (Pointer Options), verify that pointer speed is at 6/11. Lower notches (such as 2/11 or 3/11) divide sensor pulses by 4× or 8×, creating severe sluggishness.

5. Step 4: Check Software Profiles & Polling

Ensure your companion software is not automatically locking into an "Eco / Battery Saver" profile that reduces your USB polling rate down to 125 Hz or lowers DPI when on battery power.

FAQ

Mouse Too Slow FAQ

Common questions about speeding up your mouse cursor.

Why does my mouse feel like it is dragging through mud?

High friction between worn mouse skates and a dirty cloth mousepad, combined with a low 400 DPI setting on a high-resolution display, often creates a sluggish, muddy feeling.

Can a dirty sensor make a mouse feel slower?

Yes. If a hair or dust particle lodges in the optical sensor aperture, the sensor loses frame tracking data and drops coordinate packets, making the cursor stutter or drag.
