Less mouse-acceleration in Lion?

    My mouse (Microsoft Basic Optical Mouse v2.0) show far less mouse acceleration in Lion compared to Snow Lion.

    I haven't read anything about this so I guess it's something on my end? Or does other people get similar behavior in Lion?

    No problems with my Magic Mouse.
    Crazy question, but is it still slow after adjusting tracking to Fast in system preferences?

    What exactly do you mean by acceleration?
  4. macrumors 6502a


    By no problem, do you mean that you feel no difference between 10.6 an 10.7?
    Well the cursor is not as fast as in Windows, but it's managable.

    It means that the cursor movement is not linear to the mouse movement. Google it and you will see that it's a huge issue for people that want to game on their Macs, especially for Windows switchers that are not used to it. The worst part is that there is no setting in OS X to remove it.

    Here are two images that illustrate it (from a 3rd party software that removes the acceleration)

    Subjectively it feels a little different to me, but I've never had problems with OS X's mouse acceleration anyway, whether in games or otherwise.

    I don't notice a difference between 10.6 and 10.7 as far as tracking speed, but I don't do much gaming and mouse speed is not an issue for me.
    I don't use Windows on this Mac, so I am not sure about the speed in between Mac/Windows.

    I am begging Lion to have an option to turn mouse acceleration off. I've tried most of these 3rd party programs, and they don't really help. It really affects how well you can play RTSs and FPSs. Please, Apple, just give up an option like Windows does!

    What program is that? And yes, I'm also noticing better (i.e. less accelerated) mouse movement in Lion (using Magic Mouse).

    Nice to hear! I began to thought it was just an illusion but I guess I'm wrong \o/

    It was a picture from http://triq.net/mac/mouse-acceleration-preference-pane-mac-os-x
    But I prefer USB Overdrive

    I don't know if it is really less mouse acceleration, but I think that now the mouse behavior seems more natural.

    all I have to say is thank god Apple fixed this problem with Lion. My Logitech mighty mouse finally works properly without steer mouse and a ton of other garbage. Decelerate? No thanks.

    Sorry this post was unhelpful, but I know I can't be the only one who is not bummed about Apple fixing the algorithm.

    Yes the mouse acceleration is much better now on OSX Lion. No longer that "move it slowly and it's stuck in mud, move it little bit faster and it flies around" crap.

    SteerMouse is still the only thing that reliably gives Windows-like mouse movement in my experience. USB Overdrive doesn't seem to be developed anymore.

    I have noticed a similar issue with Mac OS, but I did not have a mouse plugged in under SL to know if things have changed in Lion. However, I really notice a marked difference in the acceleration and speed of my mouse while in OS X and under Windows 7 in Boot Camp. The mouse is much more responsive under Win7. I prefer my tracking speed to be maxed out. I find Mac OS to about 50% slower in terms of its overall tracking speed, but what I really notice is that it takes a 'long' time for the mouse to actually accelerate to that full speed. When I move the mouse in OS X, it's as if I have to overcome some kind of digital friction and it takes the mouse a second to speed up. All the settings seem fine. Under Win7, the mouse is quick and responsive. When I move my hand quickly, the mouse moves quickly. In OS X, when I move my hand quickly, the mouse takes its time to work up to full speed (we're talking about a second at most, but it's still annoying). The trackpad is fine on the Mac, but something is definitely amiss regarding the mouse. I don't have this problem with Leopard on my PowerMac G4, but I really notice it on my Mini running Lion (I've not plugged a mouse into my MBP - ever).

    ^ this worked fine for me, thanks!
