The title is pretty simple, and self explanatory. Will the HD Graphics/330M combo, or the 9400M/9600M GT ever be able to switch back and forth in Windows? And regardless of if it's possible, what is the limitation, drivers, other software, or a physical hardware limitation? It would be a nice way to get more battery life out of Bootcamp.
MPBr, 15", Early 2013 with dual graphics (Intel HD Graphics and AMD Radeon)
Running Maverics 10.9.3
What is happening:
1. Machine doesn't switch to AMD graphics no matter whatever app is running. In activity monitor even if some apps say "Requires High Perf GPU", the graphics card being used is still "Integrated".
2. Connecting to an external display via thunderbolt or HDMI doesn't work (external display doesn't turn on) either as it required discrete graphics too.
3. After a reboot (at what time I believe machine tries to use discrete graphics card), the display is always blank. Even the Apple logo on back of lid is turned off. Only way to get the display back is to close the lid and open it after 10 ~ 15 seconds at which time it probably switch back to integrated and comes alive.
What I have tried:
1. Reset PRAM. 2. Reset SMC. 3. Tried gfxCardStatus [URL] to no avail. If I manually switch to discrete card, gfxCardStatus checkmark say it has switched, but it doesn't. 4. Tried booting into hardware diagnosis (pressing D while booting) but was unable to get the screen turned on to proceed.
Does anybody experience any delays with the auto graphics switching on the late 2010 MBPs? I mean serious delays? Mine seems to be very slow at making the switch. Say if I open a PDF that has a load of images in and start to scroll at high speed to scan the document, everything becomes very stuttery. Then, after a while (very random in how long it takes) everything starts to get smoother, when I assume the NVIDIA kicks in. I thought this was meant to be more-or-less instantaneous?
My primary concern is whether or not uMBP users will ever be able to switch the graphics cards without logging out every time? I remember hearing that it was a software issue, does that mean that it might be supported in Snow Leopard?
Obviously the new Macbook Pros do not require a reboot to switch between graphics cards while the previous generation, the one which had two graphics cards made by the same company, requires a login/logout. The case made for the necessity of this login/logout has been the need for the WindowServer process to be relaunched, and to overcome this, WindowServer would need to be rewritten. Obviously that didn't happen. Further, if random Nvidia insiders are to be believed, this wasn't done using Optimus technology by Nvidia, but rather by Apple... so. How do you suppose they pulled that off?
I just plugged in my Cinema Display to my MBP for the first time, and for a while couldn't figure out why the heck the computer wasn't recognizing it (though maybe I'd gotten a bad MDP/DVI adaptor).
Then I'd noticed I'd set it via gfxCardStatus to use Intel graphics only. I released it to Dynamic -- and voila! Display recognized. Interestingly, it now also will not accept being set back to Intel only with the monitor connected.
I purchased a Macbook Pro 15" i7 last month, and since doing the migration (using the migration utility) from my old black macbook my graphics are stuck on the Nvidia graphics and is not switching to the Intel HD graphics. This is eating battery power like no tomorrow.
I have a late-2010 Macbook Pro 15" and have been having issues with gaming. Specifically, the games will freeze the system requiring a reboot. After reading further, I learned about the "Automatic Graphics Switching" mode under "Energy Saver" in the System Preferences screen. Upon disabling this setting, and locking the preferences, the games are still freezing.
I have not re-enabled this setting but when I check the settings again it is enabled. Seemingly, the OS is changing the "Automatic Graphics Switching" on its own.
See the new Macbook Pro that I recently got has two graphics cards. One, the integrated, standard issue Intel HD4000 and the other one, a Nvidea GT650M. Personally, I was thrilled to learn this. However, my Macbook Pro seems to switch in between these two and I really don't want it to do that. I would rather just make the GT 650M the main graphics card and avoid using the integrated graphics.
the new machines will switch between graphics chips. all very nice (at last), but my 15" MBP 2.8 doesn't and it's a real pain for me as I often go between apps than need the extra speed and then back to e.g. Word, and could really do with the extended battery life (I have the old style battery pack) any news if the older graphics systems can be worked to switch on the fly...i.e. without having to logout and shut down all the open apps, and work?
I just got a new MBP i7, and whenever the graphics switch from the Nvidia 330m chip to the Intel chip, the screen "flickers" black for a short moment before reappearing. Can anyone with a new MBP comment on this behavior? It doesn't happen on the switch from Intel->Nvidia, just the other way around.
I have a recurring problem where my screen (built in or external monitor/projector) will just go blank at random times. It is an unrecoverable situation and I have to do a hard power reset to get working again.
After testing several theories without success I struck upon one that showed promise. The blanking tended to occur when I was in Lion Fullscreen mode, or using a gesture to start expose - so I figured maybe it was a graphics switching issue.
So I went into System Preferences and disabled 'Automatic graphics switching'. I then ran trouble free for several days (I was typically crashing 1-2 times a day)
Then several days later it happened again and I thought I was back to square one. However, a colleague suggested I check the graphic switching setting to see if something had changed it back, and sure enough it was re-enabled.
Now I find myself in a constant battle with the system to keep disabling the 'Automatic graphics switrhing' in System Preferences.
I have tried setting it and locking it, but sooner or later it reverts. I need to know if it is possible to force it to stay disabled.

My logic board broke on my 07 mbp and i decided to buy a new 15" i7 anti glare 7200rpm. My question is how should i go about getting my files onto my new computer. I have a time machine backup, will it let me just install that onto my new computer? If so, do I want to do this or will that cause problems since its a different machine.
So for awhile I was following all of the to do about the GPU switching. Eventually I figured I would just deal with it and check back a month or so down the road. So since I've been out of the loop I was wondering if anybody can update me?
I've been using gfxcardstatus and it is very useful but would love to apple to just give us an update.
Bought a refurbed Macbook but it is running OSX 10.4.11 want to update it as none of my other toys sink up to it iPod, iPhone etc What is needed to update it. These are my specs.

One second my battery level will say 4:** remaining and the a minute or so later it will say 5:** remaining and then it will go back up to 7:**. This happens even when its fully charged or plugged in. What do you think it is? normal? Does your new MBP do the same thing?
I decided to try gfxCardStatus from a previous post to get a handle on which card is in use because I really feel like my battery usage is lacking, maybe 3 hours of continuous blogging and word processing. Nothing intensive like video. It showed the dedicated NVidia card. I switched to the Intel and no matter what I tried, I couldn't trigger the GT 330M. Video, every app, many windows. Appears to be a bug to me.
I also tried installing Windows to see if the 9600 would show up there, but I get a blank screen when booting the XP CD. I get the same blank screen when trying a Linux CD. Is this perhaps because the MBP is trying to use the 9600 but it's borked and not displaying anything.
I am thinking about switching back from Pc to the Mac; however I have a Dell 256 SSD P800 made by Samsung and was wondering if it was possible to swap the drive in the current MBP 13" with the 256 Samsung SSD? Would I need to install drivers or would it be as easy as installing the drive in the MBP and running the Snow Leopard disk?
I have an SSD in place of the usual hard disk my MBP 13" came with to which i placed in the optibay. Since i did this (yesterday) ive noticed how noisy the drive is over just using the SSD alone.
Is there a way to either powerdown the optibay drive or 'eject' it when not in use for silence and prolonged battery life? Would you recommend it? Most of the time i will just use it as a netbook unless i download media to the optibay.
