Version 6

Think I’ve worked out what the issue is/was. I as a test enabled Intel hardware acceleration and for some reason that causes more CPU usage on my system. I had noticed this way before, a long time ago so this had previously been disabled but I enabled it in the main settings and as all my cams are set to Default after a restart of the BI service they all started to use it.

My test system is now back to around 20-25%.

My CPU usage increased quite a lot and found many of the settings for my 35 individual cameras were compromised when imported by version 6. After reviewing many of the video settings and correcting them, my usage has dropped back to the 25% range where it was before upgrading. Some cameras lost their sub stream settings and required Find/Inspect to pick them back up. Though video FPS is set in each camera, I found that limiting it in BI's camera video Max Rate setting made a significant difference.
 
When you are quoting BI's CPU usage, are you looking at the actual usage in , say, Task manager, or at the CPU percentage reported by BI at the bottom of the timeline? That number, for me , is higher than the number windows reports, I think because it includes all windows usage. So BI says about 25-30%, Task manager says BI using about 17% for BI only. Just trying to fit my experience to the rest... (and I know you can set BI to use a 'Fudge" to make the two the same)

I use LibreHardwareMonitor (GitHub - LibreHardwareMonitor/LibreHardwareMonitor: Libre Hardware Monitor is free software that can monitor the temperature sensors, fan speeds, voltages, load and clock speeds of your computer.) which measures total CPU use of my BI machine. The data is captured and stored on another machine running Home Assistant. I'm running 15 cameras (all using CPAI) but, to be fair, I'm also running Plex on my BI server.

Here's a graph of the last 24 hrs.

It also uses less memory when you have those set correctly. Not sure why it defaults to 30fps.

Wow, after all these years of using BI I never knew that, all my cams are 15FPS - but I had a mix of BI defaults between 20FPS and 30FPS - Should change them all to 15FPS to match my cams or is there a need to go a little higher of say 16FPS?

I’m just using the BI mobile app to see the claimed usage

I always set it for what I have my camera set to. In the past BI would bump these up a little sometimes. Here lately mine are holding to 10fps or 15psc depending on a mix of cams. Just keep an eye on them.
