[macos]newer dolphin versions not using cpu time

[labyrinth153]

Hi there, I would like to ask if there is some oddity with Dolphin not using as much cpu time as previous versions. I am well aware the new releases are more accurate and intensive and my computer is relatively weak. My confusion is that the older release of dolphin seems to make excellent use of multi-core stressing the computer to 170-200%. The newer versions (4.0 and on) have abysmal performance and use only a partial amount of one cpu core. I would assume that dolphin would strain my system to it's limit and then see low frame rates. In this case it is acting as if it isn't particularly intensive.

Is there a way for dolphin to use both of my cores? I am quite happy to continue to use speedy and buggy 3.5 but I would like to contribute to the new versions.

Hopefully screenshots are attached. I did extensive testing and research on this before posting.
