    Since the higher end MBP's come with essentially two graphics chips, do you think it will be feasible to enable both chips to work at once?

    For example the 330M could offload some GPU work to the intel integrated graphics and increase performance past what the 330M could do alone.

    This would be very cool, and somewhat make up for the horrible 330M. I dont see any technical reason why it could not be done, and would most likely only require a firmware update to handle it.

    What do you guys think?

    It's a lot harder to get the two GPUs to work together than one might think. But regardless, Apple wouldn't allow this behaviour on the machines. They automatically disable the integrated GPU when the 330m is in use, so there is no chance of having them work in tandem.

    One needs to find out how Apple's on the fly switching works.

    How is OpenCL affected by these on the fly switches?
