I've created a program that sets the OS X mouse scaling to a truly linear scale then monitors applications to keep them from changing it (such as SC2). It also works along side most mouse control panels.
Not only this, but with Razer mice, it makes the control panel settings result in identical mouse behaviour in Windows AND OS X! The same settings will give you identical mouse feel!
This should work with _any_ mouse that allows you to set the DPI onboard or in a control panel. I am working on a version that should allow sensitivity/dpi(model specific) changes on mice that have neither.
2.24.11 - Second release!!
MAKE SURE YOU RESTART AFTER INSTALLATION! or it will not work until you do.
Please read the readme! It is important. If you have questions, please ask in this thread.
If you would like to donate, please contact me. This application is 100% free, but the medication that allows me the ability to even sit at my computer and play sc2 or program is expensive (see: http://www.teamliquid.net/forum/viewmessage.php?topic_id=163299)
Approximate Donation Breakdown (what have I done with any money I've received relative to this project)
$215 donated to child's play charity
$??? I've asked a bunch of people to donate directly to child's play instead of sending me money. I do not know the exact amount. There's been about 20 people I've asked to do this.
$175 purchased an auction lot of mechanical keyboards to facilitate another OS X gaming project I'm working on. I sold one of the keyboards for a total spent of $65. Difference was used for groceries and 2 pairs of cheap pants. Woo!
$110 Medication for myself, specifically 2 months of Acebutolol.
$70 Purchased myself a birthday present. U-he ACE - http://www.u-he.com/cms/ace
Thank you to everyone who's donated so far!
Windows guys, think of this as a CPL mouse fix that overrides in-game mouse control, except for OS X. It's quite a bit different in how it works, but the result is essentially that.
