C1 7.0.1 turns off OpenCL when "High dynamic range" is used

It seems that C1 7.0.1 turns off usage of OpenCL acceleration when the "High dynamic range" settings (Highlight or Shadow) are set to values other than default (0, 0). I can see it happens, because image corrections (white balance, exposure) become not smooth and export to jpegs takes much longer time.

This article

explains, that there are really some certain settings, which force C1 to bypass using OpenCL and "...use the normal processing pipeline:
· Use of LCC
· Use of BW tool
· Use of Sharpening falloff
· Use of Watermark
· Local Adjustments
· Use of Spot Removal
"
But "High dynamic range" settings are not included in this list, so I guess OpenCL acceleration should be turned on when using them?

My system:
C1 7.0.1 x64
Win7 x64
Core i7 3770
32Gb RAM
Nvidia GTX 460

  Your observation is correct, the documentation is not.

  This explains a lot, as I generally adjust at least one of those hdr sliders.
