Pen pressure not recognized on samsung tablet

i just got a new windows 8 tablet and thought I would try photoshop to see how the pen works vs. my wacom.

i cannot get any pressure control in cs6.

I checked with samsung and the driver is up to date and the pen works in one note and ms photo but not cs6

samsumg claims to be using a wacom driver in their sPen but they supply the driver. The pen is essentially the wacom pen and my intuios pen works on the tablet the same as the samsumg.

any idea why cs6 won't recognize the pressure?
