RaceRender not using full cpu capacity.
I've recently upgraded my pc and whilst stress testing, I ran various programs to load up the cpu cores and check temperatures.
I noticed RaceRender only sits at around 40% on all cores and the system temperature drops.
Is there a particular reason it isn't using more processing power?
Even when reading from one ssd and writing to another, its the same.

Same here. There doesn't seem to be any bottleneck on the system.

I should mention that when I have 2 renderings running in parallel, the cpu is ~75-80%.

The CPU utilization can vary quite a bit depending on your project configuration, video files, storage device speeds, etc. Sometimes when CPU use is low, it's because we're waiting on GPU video decoding / encoding and/or file I/O, and other times it's because we're rendering a display that isn't designed for multi-core, which may or may not be intentional (some aspects of video compositing need to be done in sequence, rather than parallel).
Lower CPU use does mean that the CPU has more processing power to spare, but typically we're waiting on something before we can give it more data to work with. If the tasks we run were just less efficient to begin with, then you would have seen higher CPU utilization and may not even question it. This is all being observed and kept in mind as I explore more optimization opportunities that can come along with faster systems, but ultimately it's lower overall processing time that we want, rather than simply pegging the CPU at 100%.

Figure I may as well pile on.
Just picked up a new 16 core/32 thread AMD 5950x and Nvidia 3070 to replace my old 4 core/8 thread Intel 4790K and Nvidia 780ti. Rendering the same 1 minute 19 second video went from 7 minutes 13 seconds down to 3 minutes 22 seconds.
That's pretty nice, but watching utilization across CPU (25%), Disk (<1%), and GPU (25%) is a little underwhelming. My video preprocessing in Davinci Resolve dropped from about 3 hours down to 3 minutes; so I was hoping for a little better than a 2x speed up in RaceRender. I do have a number of fairly complex display objects, but I can't imagine that's the limiting factor here.
