Anyone interested in running Blue Iris with 14 cameras on an i3 at 25% CPU usage?

What did you turn on? high performance or limit decoding or both. what exact model i5, i5 itself is a meaningless term. What frame rates? Are you playing all 3 cameras at once?
The high performance mode! The i5 is i5 6600. The FPS is 15fps for each camera, at 4 MP.
 
I’m only playing back one camera at a time. Goes from 30% at idle to 85% to 95% when playing back a single 4MP camera at 4x. Seems strange.
