Topic: Dropzone causes MBP to switch from integrated graphics to dedi GPU
I found out using gfxCardStatus that Dropzone (2.3) causes my late 2011 MacBook Pro (running Lion) to switch from the integrated Intel graphics to the dedicated Radeon GPU. It's not a problem when it's running on the power supply, but it will drain the battery quicker when it's not.
Since Dropzone is not graphically intensive, I wouldn't expect it to trigger that switch. I hope you'll consider fixing it soon.
