https://www.notebookcheck.net/Intel-HD-Graphics-520.149940.0.html Today I checked the graphics card driver directory again and it turned out that the OpenCL.dll library is there. I didn't have to install anything.
It was enough to set: Program Option (up / right corner) or View> Display> OpenCL> check Enable OpenCL (visible my Intel Graphics HD 520)> OK
And the program ran without any problems - it does not stutter when opening other applications,
the CPU load has dropped by about 10% and is from 15 to 32%, the waterfall resolution improved.
My RAM is about 47% occupied with Bandwight 1MHz, but increasing the bandwidth to 2MHz exhausts it completely and the receiver stutters. It will be necessary to increase the RAM to 16 GB which (supposedly) ensures smooth operation up to 10MB of processed bandwidth.
I think that the transmission speed via the USB3 cable is not a problem here, but the RAM size, which I can see on the indicator in the lower right corner of the program window.
In a word, I was able to run OpenCL/FFT without problems!
