Mouse Speed Switcher

Switch the Windows mouse speed (sensitivity) from your Stream Deck by task: one key takes the pointer from a slow, precise speed for photo editing, CAD or pixel art to a fast speed for big screens and multiple monitors, and back. Pointer precision (mouse acceleration) and wheel scroll lines switch too, and the key shows the current Windows pointer speed.

Features

Mouse Speed: two sets, such as Precise (5, precision off) and Fast (14, precision on); each press goes to the other

Pointer Precision: "Enhance pointer precision" on or off

Scroll Lines: wheel lines per notch, such as 3 and 8

Speed Dial for Stream Deck +: turn for speed 1 to 20, press for precision, touch to go back to your speed

Also for games that use the Windows cursor (common in strategy, MOBA, MMO and card games)

The keys follow changes made in Windows Settings or another app

Saved like the Settings app saves them, so changes survive a restart

If Windows refuses a change, the key says so and shows the real value

Privacy

Runs entirely on your PC. No account, no telemetry, no network requests.

Requirements and limits

Windows 10 or later, Stream Deck app 6.9 or later

Changes the Windows pointer speed, not the DPI of the mouse

Games that read the mouse directly (Raw Input, as most first-person shooters do) ignore these Windows settings: their in-game sensitivity does not change. Set it in the game.

First release with four actions. Mouse Speed switches the Windows pointer speed and pointer precision between two sets (for example Precise and Fast). Pointer Precision turns mouse acceleration on or off. Scroll Lines switches the wheel scroll lines. Speed Dial for Stream Deck + changes the speed by turning. English and Japanese.
