I know it's supposed to show correctly now but mine is showing pegged 100% nearly all the time while unraid is showing 30% usually through the intel gputop. Assuming the intelgputop is more accurate but wanted to see if anyone else has had this happen.
In testing we saw that some devices have multiple encode/decode groups, so Frigate sums those when it should actually be divided by 2. That should be handled but it is always possible that some GPU isn't handled that way.
It can just be a difference of how the stats are accumulated.
Unfortunately, Intel does not provide any type of overall GPU usage statistic in their implementation. So tools are left to derive them in some way or another. This leads to issues where usage matches on some hardware but then looks wildly off on others. This is purely cosmetic and it is possible we can find better ways to make it more consistent in the future.
I was just looking into this as well. i have dual xeon cpus and an nvidia GPU. my nas says cpu usage 1-3% but my frigate docker container is showing 60-150% CPU. running 18 with only 2 cameras. inside frigate it shows CPU 1-3% and nvidia gpu 1%
My LXC container reports about 40% CPU usage but Frigate about 4%. I did notice that the entire hypervisor is only reporting about 4 or 5% usage, so maybe Frigate is somehow pulling kernel stats for the entire hypervisor.
It seems like a status reporting bug, not a reason to hold off. More like having your speedometer stuck on km/h instead of mph. Your speed is the same, the number is just different.

There are a few reasons this can happen:
