![]() If you change to dynamic switching or discrete only any process that was hungry will become dependent. A hungry process is one that wants to use the discrete gpu but is not allowed because you have set integrated only. On the other hand if you want maximum performance all the time, then discrete only will make sure the most powerful GPU is fired up.įor most situations OS X does a decent job of managing power considerations, but if you want a little more control, gfxCardStatus will let you set up GPU power schemes to define which chip is used depending on power source. A dependent process is one that is currently using your discrete gpu. If you want to save as much battery power as possible, leaving it on integrated only will ensure that the power hungry discrete GPU doesn't fire up. ![]() A drop down menu provides you with three options: Integrated Only Discrete Only and Dynamic Switching, which is the system default that lets OS X decide which graphics card is required. If you want to save as much battery power as possible, leaving it on integrated only will ensure that the power hungry discrete GPU doesnt fire up. Sitting up in your menu bar, gfxCardStatus shows you at a glance which card is currently active, but more than that, it actually allows you to manually switch between the GPUs. That's where gfxCardStatus comes to the rescue. 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. features: Growl or Notification Center notifications when the GPU changes. It's often tricky to know which card is currently in use as the switch between the two is seamless. d youre using the higher-powered discrete GPU. For MacBook Pro users who want to manually control their GPU use, you can use a third party tool like GFXCardStatus which has been around for quite some time and still works on most modern MacBook Pro models as well.Some newer MacBook Pros have been packing dual graphics cards for a while now, with the ability to dynamically switch between them - integrated for battery life and discrete for performance. To verify this bug: - install gfxCardStatus (Marcias link) and verify that your mac supports dynamic GPU switching (only recent Macs do).You can always return to the Energy preference panel to re-enable the GPU switching feature if desired. ![]() This may decrease battery life.” – if you are not OK with that do not disable this option
