Stephen,
My set up - 12 core 2013 Mac Pro and a 6 core Mini Mac 2018 slave using VEP 6. Upgraded to VEP 7 (beacause retina update does not work in VEP 6) and and new Pro Instrument 2 retina - it looks gorgeous! However, my CPU went through the roof/ buffer sizes went up,up,up. I had to revert, brook my heart as everything was so clear. Paul, I for one could live with with Pro Instrument 2 at 100%. I look forward to VSL working on the performance issues. Thank you, Eloy
