Low OpenGL score

Hey,

I've recently installed MacOS on my PC using the 10.12.6 image from amd-osx.com and have installed the Nvidia Web Driver with the NvidiaWeb option turned on inside clover.

However , when I compare the cinebench r15 score to the score I got in Windows It's particularly low. In Windows I got around 82 FPS whereas in MacOS , I get 43 FPS.

Any Suggestions?
