we did detailed testing and fed back everything (through our dealer) to davinci. We can get to 95+% CPU usage in 14.01 creating editorial files but this drops to about 32% with 14.3.and interestingly the latest redcine which is basically the same SDK with a GUI can make the CPUs sit at 100%.ġ4.01 is fine but everything later with r3ds does not decode properly.
actually our example of the problem is even more acute. We have the exact same problem on a z8 with 28 (56) cores which we reported a month ago. cine, DJI DNG raw files work ok, only R3D decode is broken in versions after 14.01Ĭopying the Red libraries from 14.01 to 14.3 does not work, Resolve does not launch Switching Color Science Version 2/Version 3 has no effect, set Color Science Original = black frameġ4.01 playback is as expected, 14.1-14.3 playback is broken with all else being the same.Īrri65, Phantom. When Resolve switched from Red SDK 6.2.2 to SDK 7.05/7.06 (Ipp2 support) something was broken, decode performance for Full Resolution Premium is horrible due to lack of cpu utilization. If your timeline resolution is less than 4k, r3d compression is > 10:1, or decode is not Full Res Premium, you will probably not notice the problem. Real time/full resolution/framerate, with 70-80% CPU usage RedCine 50.2/ R3d SDK 7.07 works as expected in config.dat has no effect, Can not switch between CPU/GPU decodeĬan only playback full fps at R3d Half/Good with other settings unchanged.
R3D decode uses only 16 threads/cores, CPU utilization is below 20%, GPU utilization is 10%Ĭonfig.dat thread settings have no effect. Playback with multiple node correction is real time/full resolution/framerate, with 60-70% CPU usage, GPU utilization is 30%Ĭonfig.Dat DT.Manager/Dt.Manager.Red Thread settings are respected, increasing from default 8 to the max of 32 increase performance on 60 core machine Resolve 14.01 / R3D SDK 6.2.2 works as expected Workstation: 60 Cores/128gb/2x GTX-1080ti/Decklink 12G extreme/900MB/Sec raid Poor R3d decode performance, Full Res Premium decode broken in Resolve Studio 14.1,14.2,14.3 - works as expected in 14.01
