High resolution and high framerate mouse coordinates on OSX? (Or other solution?)

Question

I\'d like to get mouse movements in high resolution and high framerate on OSX.

\"High framerate\" = 60 fps or higher (preferably > 120)
\"High resolution\" = Sub

Answer 1

If you are using the IOHIDDevice callbacks for the mouse you can use this to get a double value:

double doubleValue = IOHIDValueGetScaledValue(inIOHIDValueRef, kIOHIDTransactionDirectionTypeOutput);
