Brush hesitation on Mavericks Hackintosh

Hi all,

I just upgraded my Hackintosh to Mavericks, and now I’m getting a tiny brush stutter when sculpting.
It’s minute, but it’s definitely there.

Ran like a dream under ML.
Re-installed 4R6, but no joy.
Currently working on a 1.5 mill poly model, so not even taxing the software.
Mem is set to max 4Gb etc

Any help or suggestions appreciated

cheers
Matt

Hardware is:
Gigabyte H77N wifi Motherboard
EVGA 650ti 1Gb graphics card
Intel i7 3770 cpu @3.9Ghz
16 Gb mem @ 1600MHz
240Gb ssd boot disk (new with the upgrade to mavericks)
2 x 24" HD monitors
Wacom intuos 3, Steelseries keyboard and Razer Nostromo keypad for all those ZBrush shortcuts
