Poor R3d decode performance, Full Res Premium decode broken in Resolve Studio 14.1,14.2,14.3 - works as expected in 14.01
workstation: 60 Cores/128gb/2x GTX-1080ti/Decklink 12G extreme/900MB/Sec raid
Source: 6144x3160 5:1 R3D 23.976
Decode Quality: Full Res Premium / 16
Timeline 4096x2160 23.976
Decklink 12G extreme UHD 2160p/23.976
Output Scaling 3840x2160
Minimize interface updates - Disabled
Hide UI overlays - Disabled
Resolve 14.01 / R3D SDK 6.2.2 works as expected
Playback with multiple node correction is real time/full resolution/framerate, with 60-70% CPU usage, GPU utilization is 30%
Decode uses all available cores
Config.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 14.1,14.2,14.3 / R3D SDK 7.05/7.06 does NOT work as expected
R3D decode uses only 16 threads/cores, CPU utilization is below 20%, GPU utilization is 10%
Playback is only 5fps
config.dat thread settings have no effect.
Red.GPU.Enable in config.dat has no effect, Can not switch between CPU/GPU decode
Can only playback full fps at R3d Half/Good with other settings unchanged.
RedCine 50.2/ R3d SDK 7.07 works as expected
Source: 6144x3160 5:1 R3D 23.976
Full Res Premium
Decklink 12G extreme UHD 2160p/23.976
Real time/full resolution/framerate, with 70-80% CPU usage

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.
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. Switching Color Science Version 2/Version 3 has no effect, set Color Science Original = black frame
14.01 playback is as expected, 14.1-14.3 playback is broken with all else being the same.
Arri65 , Phantom .cine, DJI DNG raw files work ok, only R3D decode is broken in versions after 14.01
copying the Red libraries from 14.01 to 14.3 does not work, Resolve does not launch
