GfxCardStatus solves this problem by allowing the user to switch between graphics subsystems at will. Discrete Only: Forces the more power-hungry graphics on and disallows automatic switching.
Integrated Only: Forces the more battery-friendly graphics on and disallows automatic switching.Dynamic Switching: An alias for the built-in automatic graphics switching feature in OS X.graphics switching modes: three modes of operation This has resulted in significant reduction of battery life for some users, whose MacBook Pros engage the higher-power-usage NVIDIA graphics during seemingly non-GPU-intensive applications. Unfortunately, although there is a built-in option to keep the higher-power NVIDIA card on at all times, there is no option to keep it off at all times. MacBook Pro (Mid-2010), Core i5 or Corei7, 15″ and 17″ models automatically switch between integrated Intel (lower power) and NVIDIA (higher power) graphics. Manually switch to Integrated Only or Discrete Only mode to force one GPU on or the other.The Dependencies list: open the gfxCardStatus menu when your discrete GPU is active to see what is turning it on.Growl or Notification Center notifications when the GPU changes.graphics switching modes: three modes of operation.
