MBPro mid-2014 16GB, 1TB SSD, Quad Corei7, Nvidia 750 OCLP 2.2 Sequoia 15.2

After upgrading to OCLP 2.2 & Sequoia from OCLP 2.1 & 15.1, every process, like extracting audio from a video using iMovie is glacially slow. e.g. took overnight to extract an hour of audio which took minutes before the upgrade. Applyng an EQ in Wavepad takes hours which used to take seconds. Further, activity monitor now shows 0 GPU usage for anything.
