Higher CPU after swapping out Foscam FI9831W with Amcrest IP4M-1041W - what could I try?

I needed to replace a broken Foscam cam. My other cameras are Hikvison domes. Ended up with the Amcrest IP4M-1041W. The CPU went to 59% without UI and 89% with UI. Prior, with Foscam, CPU without UI was below 50%. Of course it is a 4MP vs 1.3MP cam.
It has been a while since I played with settings to manage BlueIris CPU. I already changed the camera to 1080p (on the camera web setting).
 
wow! CPU down to 37%.
I enabled it in the camera web settings and then had to select it in the BlueIris drop-down box.

Is this best practice to use sub streams? What resolution is advisable for sub-stream to still have good motion detection?
Does it then make sense to increase main stream video to max resolution?

My sub-stream is on 640x480 30FPS 512 Kb/S

P.S. non of my hikvision outdoor cams have sub stream configured....
 
Yes, you should use substreams for every camera and watch the CPU drop.

For most, D1 is sufficient for substream and adequate motion detection.

You could also drop FPS to 15.

And you should always run mainstream and native resolution of camera if possible.

So, this is one of the moments where I feel like a dummy. After using BlueIris for years didn't know about that.
Server only CPU is now down to 15%!
In my defense, BlueIris config-detect also did not set it up. Talking about that. I forced BlueIris for my Hikvisions's DS-2CD2542FWD to stream paths:
main: /Streaming/Channels/101/
sub /Streaming/Channels/102/
Seemed to be ok.

Last I need to checkout my Amcrest doorbell cam.

With that CPU, I can add many more cameras

Yes. It will record in substream until triggered and then switch to mainstream. The location and options depends on the version you on.
