Ok I managed to find some 4K Blackmagic raw footage (CinemaDNG) and the 4K vs 4.6K makes a big difference. I can play and grade a 4K timeline (with 4K output to my grading monitor) with my 3D Video Monitor calibration LUT and DaVinci Color Management enabled, but I have to turn on the "Hide UI overlays for optimized playback" in order to achieve realtime playback. But if I do that, it pretty much feels like an HD timeline. So the 4.6K footage I had found earlier is definitely harder on the system (by a good amount), most likely due to the math involved in scaling 4.6k down to 4K.
That being said, the "Hide UI overlays for optimized playback" option currently screws up the Resolve scopes (a known bug), which is a big problem for grading! Either you have external scopes, or well, I guess you're out of luck (for now).
Otherwise, I work with 4K Canon footage all the time (XF-AVC Intra) and it's much easier on the system. Same for 4K DPX... It makes sense that 4K raw footage is more demanding, although I was under the impression the raw processing was handled by GPU, which should be fine with a Titan. Unless that's only for RED and ARRI ..?
