Phase One CaptureONE Pro to Fully Utilize All GPUs Available (e.g. 2013 Mac Pro)
PhaseOne CaptureOne Pro offers “hardware acceleration”, meaning the GPU(s) and already does a standout job on utilizing hardware resources.
But PhaseOne seems to be leading the charge on GPU support—
According to Lionel Kuhlmann, R&D Manager at Phase One, a future (2014) version of Capture One will fully utilize all the installed GPUs in the system, whereas version 7.2.1 of Capture One Pro utilizes only 1 GPU.
In other words, RAW file processing should be impressively fast in this future version on the 2013 Mac Pro, but it also means that the older Mac Pro can be souped-up with a faster video card. Given that professional photographers use up to 80-megapixel digital backs, any speed gains are a welcome improvement.
