Hello, I m not sure if this can help u but I had a Hackintosh with 128 GB ram and 1 GTX1080 plus 2 2.67 xeon.
When watching some tutorials I saw the difference with the frame rate for very basic simulation on my viewport.
I decide to install win 10 on another disk, same hardware and everything became 50/60 % faster.
I migrate from Mac OS to win 10 for the speed of my 3d apps.I guees al guys working on plugins and render engine work with windows, especially due to the Cuda developement of Nvidia witch is not the best friend of Apple vision. It s not because one system is better than another is just because developpers use a tecnologie that not all brand use,also,I m not an expert so not sure if this can influence speed.
