Maybe this isn't new, but I discovered that on one of my systems, GFNSvCUDA did not recognize the integrated Intel graphics, but gfnsvocl did and recognized it as device 0. This resulted in me trying out gfnsvocl, running on the Intel graphics, and being appalled at the performance (I thought I was running on a GTX 1080).

something to be aware of.

Intel graphics chips do not support CUDA, it's kinda an Nvidia-only technology. But they do support OpenCL. So, all as expected
