If it happens not only in Minecraft, check the surface you move your mouse on. If you move from a rough to a smooth and shiny surface it changes the speed. If the surface is irregular it might happen too. Don't forget to make sure your mouse has no connectivity problems. Try using a different mouse on a flat mousepad.

guestdsbasicly my laptop runs too fast to play minecraft efficiently because it makes the mouse speed up if im running too fast i tryed a lag machine its either too laggy or wont lag me especially when i go into the space station (Galacticraft) so i need help lagging my minecraft but nothing else please (im on Windows 8, it has no logic, i think i have non either in this post i hope you understand what i mean)

Your mouse DPI is too. High your FPS is not too high. In programming, to prevent this sort of thing, functions are often multiplied by delta time (basically stuff in the code is controlled by the change in time, so your FPS doesn't affect how fast the game actually runs). Without this, days would last for different amounts of time in minecraft, and, essentially, faster PCs would have shorter days. In short, you PC speed wouldn't affect stuff like this.

Anyway, I get around 220FPS solid and my mouse does not run away. Either decrease your mouse sensitivity (ingame, or turn down your DPI if it's a gaming mouse), or get a mouse with a lower DPI.

I'd just say try another mouse and troubleshoot from there.

Alright, alright. Let me make this simple for you. Follow the steps.

Step 1.) Open Minecraft.
Step 2.) Click "Play" and let the game load.
Step 3.) Click on "Options".
Step 4.) Select "Controls".
Step 5.) At the top, there is a sensitivity bar. Lower it, and go back in game and see if it feels right.
Step 6.) If it's still too sensitive, repeat steps 3-5.


If this doesn't fix your problem, then please stop trolling. Thanks!

the mouse speeds up in minecraft because its running too fast but not in gmod or portal or other games like that

Clearly explain your problem so we can understand.

telling us that it "speeds up" is not enough to help you. If you mean that when you move the mouse and the camera whips around really fast, than that is a sensitivity issue in the settings

ClayblockSo..... your mouse is too fast?

no it speeds up randomly and its not a virus doing that i added mods for some reason that made me faster so i dont get that logic i need help getting minecraft slower ill just uninstall all of the "laggy" ones ill respond if it doesnt work but if it does i wont and if you are sending a message now for a suggestion send it still please

Can you please write correctly? I cant understand a word you are saying.

Turn down mouse sensitivity. That'll solve your problem. Should be able to do it from control panel.

Or just cap your FPS.

So..... your mouse is too fast?
