I'm reading the config guide for Resolve 9 and it says:
"DaVinci Resolve can perform RED r3d decoding at various resolutions and de-bayer qualities tomatch the realtime performance of your computer hardware. If a RED Rocket card is installed, full resolution and premium de-bayer quality of 2K filescan be achieved, as can premium de-bayer quality of 4K files at half resolution. If you plan on using aRED Rocket card in slot 4, the Mac Pro’s limitation of four PCIe slots will necessitate the use of either a PCI Express expansion chassis, an internal storage software RAID and/or a FireWire 800 drive.
"Realtime r3d decoding can be performed without the RED Rocket card but at reduced resolution and de-bayer quality. If 4K r3d files need to be processed in real time at maximum quality, a Resolve for Linux system with multiple GPUs must be used. As newer generations of faster computers become available,the realtime r3d decoding performance will increase."
Is this just for playback while color correcting, or is it also for rendering? If it's rendering, that is disappointing, to say the least. I would rather have slower than realtime with full debayer rendering. And what about 5K?
