NVIDIA has released their alternate graphics drivers for OS X Yosemite 10.10.1. These are separate from the drivers Apple ships as standard, and should be considered experimental. These drivers have been known to solve OpenCL issues with certain applications, as well as providing better native GPU power management for certain devices. NOTE: These drivers are currently the only method to get full acceleration for NVIDIA GeForce GTX 750, 750Ti, 970, and 980 'Maxwell' graphics cards. There are no current Macs with these cards, so support is absent natively in OS X. If you've installed the drivers before, you may get a notification to update to the 10.10.1 drivers from the built in System Preferences pane.
