Yes, the actual range is 0..255 -- and looking at the numbers it isn't more precise, but somehow, on this device, the actual pressure values you get while drawing are 0..1024. And there's no n-trig config utility for its wintab drivers for this device...

The way I understand it is that pressure sensitivity between n-trig and wacom is the same for brushes sizes 255 and lower.
Where wacom gains an edge is at brushes much larger than 255 wacom then gains more levels of presser sensitivity. It really does not show up till brushes are well past the 250 level. Which is fine by me as I do not use brushes that large for sketching.

Any of you have this issue ? When I draw a vertical or horizontal line in Krita with the brush it seems to activate some special gesture. It scrolls and I go out of the drawing area.
I can see a little icon with a text during 1s : "slide up" / "slide down" / "previous" / "next" according to the direction.

It happens only with the pen.
It happens only with Krita (I tested all drawing apps or apps I could)

I actually see that on the intel device as well, but I have no idea yet what it is!

So maybe it's related to Wintab drivers ?

Anyway now it's worse. I made a refresh (reinstallation of the system and apps) of the Surface, and this time I lost completely the pen pressure with Krita... arg. Only with Krita, pen pressure seems to work fine with other apps. I don't understand because I installed the same softwares and drivers than the day before.

Well... That must be something about the drivers; Krita's tablet support hasn't changed, the thing that fixed the offset was taking care of high-dpi scaling in a sort of non-standard way. Besides, I still have pressure on my intel device.

Pen pressure has been rock solid. Check for current Win8, n-trig, and wintab drivers.

Already Done. I have wintab 1.0.0.17 (last version on N-trig website), Windows 8.1 with all possible updates.
It must be related to Wintab drivers because Krita can work with pen pressure if I use a Wacom tablet!

i also have no pressure sensitivity. installed the latest n-trig drivers and fully updated windows 8.1.

Hm... But how can that be? As far as i know, its impossible to have both wacom and ntrig (or any combination of) wintab drivers installed on the same hardware. It's giving me huge trouble when testing with huion, yiynova and wacom, and my ntrig device, well, I'd never dare plugin another tablet!

just for the record i did not plug a wacom into the surface pro 3 (blasphemy)

As I recall I installed both ntrig and wintab (special version)* to get my SP3 working with everything. SO it is not a Wacom driver but a special wintab.

wait there is two seperate drivers to install? i just installed the drivers from rob's link

I did this six months ago so I am a little fuzzy, but as I recall I updated my ntrig driver and installed the ntrig ( wintab) and the really made everything work

hmmm. as far as i am aware there is only that one n-trig wintab driver? Quite frustrating. i was looking forward to using krita on this device.
