Hi Piotr,
There are in your settings that are not correct.
Did you try to uninstall Davinci Resolve Completely, delete the directories and reinstall Davinci Resolve. To finish redo the settings and test.
We have practically the same PC (You Asus X-99 Pro, i7-5960X CPU, Me: X99 AII and I6850 K) and I just tested again. I have no problem reading a HLG UHD @ 59.94 fps and Decklink Enable.
My cache is in 'Uncompressed 16-bit float - HDR' but it is not used and I can read at 59.94 fps.
Have you tried reformatting the HDD Cache?

Usage CPU - GPU : Whether CPU or GPU, there is margin. (Can you compare with your system?)

Hoping that BMD offers better than me.
