Switch your mouse speed by task from a Stream Deck key
To change your mouse speed from a Stream Deck, add Mouse Speed Switcher and press its Mouse Speed key: one press 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 always shows the current Windows pointer speed.
How do I change my mouse speed with a Stream Deck button?
Drag Mouse Speed onto a key and set two speeds, for example Precise at 5 and Fast at 14, each with pointer precision on or off. Each press switches to the other set, and the key shows which one is in use.
Can it turn mouse acceleration on and off?
Yes. The Pointer Precision key turns "Enhance pointer precision" (mouse acceleration) on or off, and each Mouse Speed set can switch it too.
Does the change stay after a restart?
Yes. The plugin saves the change in your Windows user profile, as Windows Settings does.
Does it change my aim sensitivity in shooters?
It works in games that use the Windows cursor, common in strategy, MOBA, MMO and card games, and everywhere on the desktop. Games that read the mouse directly (Raw Input, as most first-person shooters do) ignore the Windows pointer speed, so set sensitivity in those games.
Does it change the DPI of my mouse?
It changes the Windows pointer speed, which applies to every mouse on the PC. DPI is a setting of the mouse itself, changed by the mouse maker's software.
Limits
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; set sensitivity in the game.
Some mouse software sets the pointer speed back; the key then shows FAILED "not applied".
