Usually my 15inch retina MBP (2.7 i7, 16GB, 750GB SSD running 10.8.2) runs smoothly. However, when I open any application that uses the discrete graphics card, the NVIDIA GeForce Gt 650M, the animations within Mountain Lion all become jerky. This is most noticible when I opening the dock (esp maginification of icons) and opening mission control (especially scrolling between pages). They are incredible jerky and really disctact from using the computer. Once I close the app, everything goes back to normal. I've checked the behaviour by running gfxCardStatus and this confirms it's only when the NVIDIA card is being used.
I've run all the latest update.
