Try this thread for the drivers that do work for at least some people:

With my previous Surface Pro (first version) I haven't any issue with crunching but I had some kind of problem by downloading the Intel drivers as tablet is made by Microsoft the drivers were tailored for this hardware and every time I did it the drivers were not installed.

So I already had supposed now with Surface 4 and still didn't try as far as I seen that just two days ago new Intel drivers for the video card had been installed for the tablet via windows update.

Confirmed the Surface 4 Pro doesn't accept the Intel drivers for graphics card only one accepted the tailored ones from Microsoft.

I wonder whether it has to do with it using OpenCL 2.0. Has anyone gotten the current apps to run with OpenCL 2.0 drivers?

[Edit] Someone has gotten it to work but they also have the OpenCL 1.2 nVidia drivers installed.

Personally, I'd be a little worried about using a surface for GPU crunching given its limited cooling due to lack of fans. Even my gaming laptop throttles the GPU due to heat issues. Anything running at those limits will not last long.

Slicker, you´re right but I use to work with it for testing purposes and not for a long time.
