(Using gfxCard Status to force one or the other). The utility also shows which apps are currently using the 330M, if the 330M is the active GPU.Īlso, as noted in this Apple Knowledge Base article, when the MacBook Pro is connected to an external display, “high-performance graphics will remain on until you disconnect the display. ” How to turn off the higher-power-usage NVIDIA graphics?Īs of yet, the only method for disengaging the NVIDIA graphics card is to quit any processes that currently make use of it. Try with Group policy editor (Start, type gpedit and hit Enter) Set properties for key. Using gfxCardStatus, you can identify these processes, then quit them. Computer Configuration -> Windows Settings -> Security Setting -> Network List Manager Policies. You can also see right away which card is being used (in the example below that would be the Intel HD Graphics). Applications/utilities that trigger NVIDIA graphics gfxCardStatus is a really handy way to keep tabs on what your Mac is doing automatically. I prefer to keep it set to the Dynamic Switching algorithm and. gfxCardStatus is a free menu bar application that keeps track of which graphics card your MacBook Pro is using at any given time. Here’s an informal list of applications and utilities that appear to trigger the NVIDIA graphics. Features: Simple, clean 'i' and 'n' icons that signify Intel HD Graphics, and NVIDIA GeForce GT 330M graphics, respectively. Automatically updates when the GPU switches, in real time. On my MacBook Pro with automatic graphics switching, graphics card is switched to NVidia after showing 'Details' popup window, but it never switches back after closing it. If you have something to add, please let us know in the comments. This is very annoying, because you have to restart Viscosity (and all VPNs in turn) to switch graphics card back to Intel. #Gfxcardstatus keeps switching install#.In the application, you can see which process(es) were responsible for the change to discrete graphics, and optionally switch GPUs. The only exception to this (thus far) unrestricted ability to use Intel HD graphics in favor of the GT 330M is when an external display is connected. ![]() ![]() Use of an external display is only possible through the GT 330M due to physical connector restrictions. At the same time, if you're using a multiple monitor setup, you're also likely at a desk, and thus don't need the power savings. We're still playing around with it, but thus far everything appears to work perfectly, and we're switching from the GT 330M back to Intel HD graphics dynamically without any major issue. Hit up the link and give it a shot if you're feeling adventuresome. Update: The developer is fast, and has updated gfxCardStatus to 1.6.1 minutes after we posted the story. Nothing has really changed though aside from some tweaks mentioning that manual switching is obviously highly experimental, and removal of the dependent processes tab when Intel HD graphics is in use. We haven't yet run into any drastic problems, but have only tested with basic things like Photoshop CS4 with GPU acceleration disabled (this previously caused a switch to the 330M), X11 under OS X, and a few other simple 3D programs that previously triggered a GPU switch, like Grapher. ![]() Update 2:Cody has updated gfxCardStatus to 1.7 which now includes support for locking the graphics subsystem to either the Intel Integrated HD or 330M full time, instead of requiring you to manually switch. This makes a lot more sense, and essentially now brings the 2010 MacBook Pro graphics subsystem back to parity with the level of control present before the refresh.
