nVidia Drivers for MacOSX underperform - here are verifying Benchmarks
Unigine Valley Benchmark comparison, for Mac and Windows, Radeon and nVidia, OpenGL and Directx which clearly show, that while Radeon GPUs are performing about equal in Windows and Macosx, nVidia GPUs are much worse in MacOSX.
It's a pity there is no real support for nVidia in MacOSX, in mojave there will never be?!
Here are the benchmarks for Unigine Valley, 1080 Extreme HD, external Monitor: It is quite obvious the "downfall" of the nVidia Benchmark for MacOSX:
|AMD Radeon Pro 560X||nVidia Geforce GTX 1080 Ti|
-15-inch Macbook Pro 2018
