Hi All, I've installed gfxCardStatus, which lets you see what card is currently in use: the hd3000 or the 6750m. I've noticed no matter what I do, the 6750m is always in use. Even just browsing the web in firefox while on battery power. If i manually switch to the hd3000 (force integrated only mode), i notice scrolling is choppy on firefox. Does this mean the hd3000 is not suitable to drive the 17" version of the MBP at all? If other people with 17" MBPs want to test what I'm talking about; in gfxCardStatus, select 'integrated only', then once it switches select 'dynamic switching'. In my case no matter what I am doing, the dynamic switching (aka OSX's normal behaviour) switches to the discrete. Any ideas on whether this is a solvable problem or a fact of life? I'd like to get some extra battery if possible. I'm a new mac convert by the way. Is there something like Aero on windows which uses more graphical horsepower that I could turn off to prolong battery and give the integrated graphics an easier time? Thanks.
