Is Blue Iris worth pursuing for my situation, or am I pushing it beyond its practical comfort zone?

@chaosengine, you indicated you felt that image D looks like a GPU-bound issue. Can you elaborate on what makes you suspect that? GPU is at 39% in that image. I am not sure what aspect of the GPU that "39%" refers to (3D, decode, etc.) or if it is a heuristic guess. Any thoughts? Also, agree the CPU is old but it doesn't seem bound. In fact, I was quite surprised how old it was when I was looking up info for this thread.

I mean the spikes in the GPU 0 graph in image D. Especially the third spike is far too wide. That is the typical “table mountain” shape you see when the GPU is hitting a limit. The spikes should normally be much sharper and shorter.
Also, 39% utilization while basically idle is already quite high. On my system it is around 15–19% while UI3 is showing the overview of all cameras at 10 FPS. And that load only comes from decoding 3× 3.7 MP cameras where I cannot use substreams.

Here are two screenshots from my dedicated BI machine (UI3 running). You can also see how the decode performance drops every time the AI object detection kicks in, and that adding more than about 12 CPU cores does not really help much anymore.

Additionally, there are always reports about all kinds of strange video decode issues related to different Nvidia driver versions. That is why I stayed on 560.76, because everything is stable and working properly for me with that version.
