I only know -- I still haven't got a surface pro 3 -- that on my Intel device, I needed to install the ntrig wintab driver, then hack Krita to fix the pressure range reported by the driver and everything was fine. I have reported two problems to n-trig, but (of course) not heard back from them. I also haven't tried to update the device.

But basically, logic dictates that if Krita worked, and then, after a reinstall of the system, the same version of Krita doesn't work, it doesn't depend on Krita...

Do check, though: install debugview and run krita with ctrl-alt-t to get a debug log for tablet handling, and see what that outputs.

thank you for the help but both these links lead to the same set of drivers wintab 1.0.0.17-64-bit.

i did email n-trig the other day about this issue also. still awaiting a reply.

ha! strangely the 32x version of krita works flawlessly with the 64x n-trig drivers. there is now pressure sensitivity.

That's not so weird, the 32 bits version 2.8.3, which still uses the Qt tablet support classes. I haven't made 32 bits builds of 2.9 beta1 yet. However, I'm really sorry, but if a 2.9 beta worked before reinstalling windows/drivers, and if it no longer works after that, with the same version of Krita it simply cannot be a bug in Krita.

Also, Krita still works fine with the n-trig drivers on my intel laptop -- latest version that I built myself (except for the pressure range bug in the driver, which caused interrupted lines, but the Surface Pro doesn't seem to have that). I'm using 1.0.0.17 wintab drivers from n-trig.

its fine im more than happy to be able to use the 32bit version of krita. it works extremely well. my only concern was the pop up at the start that explained that running the 32bit on a 64bit device was not recommended. ive been running it for the last few hours and haven't came across any problems accept using it in portrait view, which has offset issues - (which doesn't bother me as i use it in landscape anyway )
apart from all that its absolutely wonderful!

happy new year everybody!

Must say I'm wary about replying to this thread. I've only been using the SP3 for a few weeks and only learned of and installed Krita yesterday!, so please take the following with a huge pinch of salt and apologies if I'm off-base.

I was looking for a replacement for Procreate on the iPad -- where I had access to some great brush tools, all user modifiable -- and came across mention of Krita. I installed it, tried it out with the SP3 pen and was disappointed to see no pressure sensitivity. I dug around, learned of the Ntrig Wintab drivers, installed them and found the sensitivity seemed to now be working. I didn't do any more yesterday but, in looking for info on how to use the SP3 pen with Krita today, came across this thread and was surprised that it seemed not to be working for others, so tried the pen with Krita again in more detail.

As I said, it does seem to be mostly working for me. I have a Win8.1 i5/8Gb/256Gb Surface Pro 3 and have installed x64 version of Krita. The pressure sensitivity seems to ramp up quickly so that a line moves from fine to thick (I don't know how to customise the response to pressure) quickly. Pressing really hard makes the thick line disappear in sections so you only end up with small bits of the line showing but, since the thick line appears with only moderate pressure, it isn't necessary to press too hard. I tried all the brushes in the default setup and those expected to have pressure sensitivity did have it, more or less.

I am not an artist (I am looking for ways into preparing images for printmaking), nor, clearly, do I know anything about Krita, but if anyone wants me to test anything else out or know more about my setup, please shout -- but with clear novice-style instructions for how I can help.

Cheers,
Tony.

Tonylinde, the pressure issue is something boud fixed recently. You should try the next krita 2.9 beta.

In the meantime, there's a pressure sensitivity curve in settings->configure krita-> tablet.
Make it concave, like a skating ramp, and it should fix the pressure a little bit. The 2.9 fix should properly fix the pressure

Thanks for the pointer. Looks a great app but seriously huge amount of stuff to learn.

Tony,
Krita is coming along very nicely and I do not seem to be having many of the issues that other are having. At this time I have not finished a professional piece with Krita due to beta and I am not an expert with the software.
That said I am using Manga Studio 5 on my SP3 i7, creating 11"x17" @ 600 dpi with no issues at all (I don't think ipad can do that resolution needed for pro print) . I find manga Studio inking better than any program out there (including photoshop), and any brush can be a vector ( even air brush). I did buy the Frendon brushes for like $5? though. You can get Manga Studio 5 on Amazon for $35 (including shipping).
Krita has some very nice features that once it is stable and adds layer effects it will be very strong competition with most drawing programs.

Pretty much all paint applications for iOS and Android are limited in resolution to what the GPU allows for texture sizes. Usually, the maximum is 4096x4096 -- it's either that, or be really slow, because the ARM CPU's really don't have the power.

Resolution like 4096x4096 is not the only factor, as you need a minimum of 300 dpi for print work and 600 dpi for mid to high end printers. That said I have also tested Krita at 11"x17" @ 600 dpi on a Surface pro 3 i7. My initial testing is very favorable, but as I stated I have not done a full professional pictures with many layers for print yet. Although, I assume it will perform admirably.
Soon as we get a stable release with new features I will be doing a full shake down, and producing a high res image along with a lengthily review. It would be unfair to proceed until stable.

Look forward to your shakedown, Rob. My main interest is in quickly sketching ideas for printmaking: Procreate on iPad was ideal for that as it was relatively simple to get into but offered customisable brushes so I could, eg, create one that mimicked carborundum effects on a drypoint. I have ArtRage (bought when heavily discounted) but cannot really afford Manga Studio (UK prices not so good). Krita does look like it'll offer what I want so I hope I can learn enough to understand what I need to do to achieve what I want.

Tony,
Have you tried the MS Surface Hub to improve your pen pressure experience?

The pressure works fine in the Hub, Rob. Even at the heaviest pressure, the line still draws evenly in the Hub test box. It is only in Krita that excess pressure breaks the line up. It isn't a problem: I'm happier with the pressure curve so that I don't need to press too hard to get the maximum level.
