Hello,
Context:
Primary Millumin Machine:
-Mid 2015 Retina MBP
-16GB RAM
-Radeon R9 M370X GPU
-2.8 GHZ CPU
-1TB SSD
Backup Millumin Machine:
-Mid 2015 Retina MBP
-16GB RAM
-Radeon R9 M370X GPU
-2.5 GHZ CPU
-500GB SSD
OSX installed on the same day last year and tweaked the same on each machine.
Note the differences between the two machines are CPU speed and SSD storage. When the project is set to a single 1920x1080p60 output and playing a 1920x1080p30 video, the Primary machine's CPU is racing super high with VTDecoderXPCService between 130-260% and Millumin 3 at around 150% and FPS drops to around 30, whereas the Backup machine is running at a relaxed pace with FPS at around 60. I've reset the machines and this persists. Not much else is running on the machines.
What could be happening? Why is the slightly heavier duty machine struggling?
