[solved] OpenCL not working

[dgud]

I build the 32bits wings on my home computer with nvidia toolkit and get Opencl 1.1 libraries.

I build the 64bits wings on my laptop with Intel toolkit and thus get OpenCL 1.2 libraries,
which doesn't work currently with Nvidia drivers.

But it means I must build everything on Nvidia to get it to work on every card, which
means setup another 64b dev environment or that I must fix opencl
library to check version at runtime and load new functions if available.

Stem: It priorities gpu before cpu, you can see and manually change that in your preferences file.
It only uses one device, it's complex enough anyway and I do not want to duplicate the memory usage.
