Description

So far I've used the mother board graphic driver.
I've installed as graphic card Geforce gtx 1050ti (to improve dt speed).
Since then I cannot start dt anymore.
Same error with the master version.
Backtraces attached.

Nvidia Bios info: Version 86.7.42.0.1d

Strange. In backtrace I see "IntelOpenCL64". Does that mean dt is trying to the on board intel opencl instead of the geforce one ?

I've found the solution here:
http://www.echeng.com/journal/enabling-nvidia-gpu-for-adobe-premiere-pro-in-surface-book-2
I copy the useful part:

To do this, run regedit and navigate to:
Computer\HKEY_LOCAL_MACHINE\SOFTWARE\Khronos\OpenCL\Vendors
There will be .dll entries for NVIDIA, and for Intel (in my case, "IntelOpenCL64.dll"). Change the value for the Intel dll to "1", which will disable OpenCL for that GPU.

Is there a way dt detect the right OpenCl driver ?
