I was also really hoping to use Photoshop on my Surface Pro, but I'm having the same problem. Illustrator doesn't recognize the pen pressure either. I really hope there is a way to make this work!

Just curious.... has any of you tried the shape dynamics in photoshop and turning on pen pressure?

and in illustrator to modify the size to pressure and variation to maximum? (and of course select that brush preset that you just modified and draw with it using SHIFT+B for blob brush or B for regular brush)

I am also interested in purchasing a Surface pro so please report if this helps.

what I recently discovered in other forums is that Sketchbook Pro works flawlessly in desktop mode. Sketchbook Express in the APP mode doesn't support pressure yet.

there is no official confirmation that the surface pro uses a wacom digitizer, however a few artist friends of mine have gone to the microsoft store... brought their own wacom pens (cintiq 15x pen - older models that works with general tabletpcs) and the pro recognized it. which means that it is a wacom digitizer. it wouldn't make sense if a wacom pen works with a different digitizer board like N-trig.

also read in another forum about adobe using wintab and windows 8 wintab drivers are not there yet.

anyway... I'd be glad to know if this works or not

thanks!

Yeah, I tried that. I use a Wacom Bamboo with my desktop computer and do not have this problem, but with the Surface in Photoshop the Pen Pressure control has the exclamation point so it's not recognizing the pen, and in Illustrator, the Pressure option is grayed out. The only options I can select there are Fixed and Random, all others are grayed out.

Sketchbook and ArtRage recognize the MS Ink API (or whatever it is called) and PS/Illustrator require the WinTab drivers that I believed Adobe collaborated with MS on. N-Trig users have been victimized by the split and circular firing squad blame game between various companies for years, and I'm really surprised that it wasn't resolved before the release of the Surface Pro. What the heck are these executives paid for, to play golf?

It's working now!  And it's working beautifully I might add!
