Same post as previous, but for amd videocard, 7950, osx 10.9 vs win8+catalyst 13.8b2
OSX AMD drivers are 34% slower than windows ogl drivers and 51% slower than windows DX11 drivers
such result could be due to extreme tessellation mode and inability of osx drivers to handle it fast enough. Also 8xAA made a big hit.
