Re: CS6 big dissappointment

It's my understanding that Mercury optimized effects are only accelerated by the GPU when you playback in realtime without rendering. When you go for the render the effect is actually handled by the CPU.

If your GPU can't handle realtime playback in the mercury engine & you are relying on rendering effects before playback then you really aren't benefiting from "GPU acceleration" in that case.

The BCC keyer may actually be faster than the ultrakeyer when it comes to CPU rendering. The real benefit would be if your MBP GPU had the performance of a CUDA card(which is what we were all hoping), then rendering while editing wouldn't be necessary. Though the final render out when you export your sequence would still likely be faster with BCC if it is true that it is more efficient with CPU rendering than the ultrakeyer.
