Offload processing from GPU to CPU
I have recently bought the latest Mac Pro dual 4 core system and FCP (converted over from windows)
A number of operations require that I need to render before viewing (fair enough), however, even when rendering the CPU(s) are barely doing anything. I assume that the GPU is doing all the work.
Is there anyway to offload some or all this processing onto the many CPU cores I have ?

Hi Declan,
Which processes are you exactly talking about?
The Fxplugins work in the GPU. They could work in the CPU as well if the developer install the option.
Is also possible that you haven’t got your FC set properly for RT preview.
Do you have FC set in Unlimited RT?

I normally have it set to Unlimited RT as Safe RT usually puts the unrendered box up. I think I have it set ok now. Unlimited RT, Dynamic Quality, Full Frame rate, appears to work. However, when set to safe RT will full frame rate it needs rendering. It’s ok on the canvas window, but monitoring externally, the quality seems to drop (like preview quality not full high quality), depending on the type and amount of effects..
I would have thought that with all that CPU at FCP’s disposal, it would be able to RT render higher quality output, but it just doesn’t seem to use the CPU very much.
Even when I set it off to actually render a clip, the CPU hardly get’s off the floor, whearas I would have thought it would use whatever resources are available.

hi Declan,
the thing is that Final Cut Studio 2 is now two years old, I guess we’ll have to wait for a new version to see it fully use the multithreading capability of the 8-core Mac pros.
Cheers,
