I just upgraded my Mac Pro 5.1, 6 core, with 42gb of RAM, SSD boot and media storage drives, OS X 10.10.5 and running dual GFX cards (Quadro 4000 GUI only and GTX 970 GPU dedicated) and am still only getting10-11 frms per second using 4k ProRes444 source material with seven nodes. Granted, there are a couple of layer nodes and a ofx on one of them and I have all the optimized options selected and I even tried caching the clips but still getting slow playback. My 970 is not flashed for mac but I have installed all the correct drivers and seems to be working just as it should expect for the fact that when I run playback, the 970 pegs its Processors but doesn't touch the memory at all. (monitoring on istats) Is this normal during playback? Isn't ProRes an optimized format for Davinci? I get a couple of frame loss when in 2k and full 24 firms per second in 1080 but really I want to color in 4k for various reasons. Is this possible at all with that many nodes? Do I just need twice the CUDA cores to get realtime playback with that many nodes? To be honest, I guess I expected more out of the 970, especially with ProRes. Am I missing something? Any help is appreciated. Thanks in advance.
