Updated GTX 1080 drivers now OpenCL HW doesn't work

[TheProfessorY]

Did NVidia change an API as I now get the folllowing error.

Traceback (most recent call last):
File "C:/msys64/mingw64/lib/python2.7/site-packages/cx_Freeze/initscripts/Console.py", line 27, in
File "butterflow/main.py", line 12, in
File "butterflow/cli.py", line 287, in main
RuntimeError: opencl call failed

I am not sure when this happened but if I roll back the drivers to a very old version from a year ago it works.

Is this a known issue?

I see it is already a known issue. So please duplicate and close.

Would there be a way to force OpenCL to use the Intel IGP?
