I am using cr0.3, and Blender 2.92 on all machines. I am a bit surprised that this render which was started last night is taking quite so long. The 3 computers being used are: 1) 8-core 4.1 Ghz RTX2060 2)8-core 3.9 Ghz RTX 2070, 3) 4-core 4.1 Ghz, GTX 1050ti. I left automatic load balancing because I thought while the first few renders might take longer, it would do a more exact job of balancing the job between them over time. But the job is only 19 frames in and the reason is because the older machine seems to be having too much to do. It's on 39% now while the other computers sit idle. And I spotted it 20-30 minutes ago at 26% or so....and the other computers had finished then as well. I don't know when they finished their jobs. Surely load balancing should have worked out how long the older computer needs per tile by now and balanced its load accordingly?
