With a largely shared driver code-base across platforms, the binary graphics drivers offered by AMD and NVIDIA perform at roughly the same speed for OpenGL between Linux and Windows; that’s traditionally been the case and what Phoronix benchmarks in prior years have shown for NVIDIA and AMD. However, the OpenGL performance difference between operating systems is beginning to widen due to compositing window managers and other factors now affecting the results to a greater extent. In this article are benchmarks of the proprietary NVIDIA graphics driver from Microsoft Windows 7 and then development snapshots of Ubuntu 12.10 with Unity and KDE desktops.
