NVIDIA releases alternate graphics drivers separately on the web for each OS X build. These are different from the drivers Apple ships as standard, and should be considered experimental. In the past, the drivers have been known to solve OpenCL issues with certain applications, as well as providing better native GPU power management for certain devices. They also will enable the latest 'Maxwell' cards to work with full acceleration- NVIDIA GeForce GTX 750, 750 Ti, 950, 960, 970, 980, 980 Ti, and TITAN X.
