MC22 uses too much CPU

(1/5) > >>

Zsolt Andrasy:
I have a brand new MacBook Pro late 2016 with USB DAC and USB HDD with the song files. I am an old user of MC, now I have a latest version of MC22. I have observed my MC 22 uses too much the CPU. When it is stoped it uses 17%. I think it is unrealistic. See attached file.
Playing 16/44 Flac it is 22-28, playing 24/96 is above 30.
When I play SACD iso it could reach the 50-60%.
I think something wrong with this version.

blgentry:
I see similar behavior.  I'm using roughly 25% while playing 16/44 material, which doesn't bother me.  When I press pause, MC uses 17 to 20% CPU.  When I press Stop, MC drops to under 1% CPU.

I've noticed the "paused CPU usage" for at least a year.  I just know to press stop if it's bothering me.  In the past this paused CPU usage could be very high:  50% or more.  But I haven't seen that in a while and that was on my other Mac (2011 MBP), which I haven't used MC on in a couple of months now.

Zsolt Andrasy:
I'v uploaded three screenshot:

SACD played - extreme high CPU
SACD paused - 15%
SACD stopped -17%

Interesting.

I don't use MC for Mac, but out of curiosity, what happens if you disable the spectrum analyzer in the playing now bar at the top center?  That spectrum analyzer is a source of large mystery CPU usage on the Linux builds, so it's possible it might be contributing here.  Brian, IME on Linux, the usage is especially consistent with your description (i.e. high CPU usage is ongoing while paused but not while stopped). 

Zsolt Andrasy:
We had some serious problem with the spectrum analyzer some built ago, since we don't use it - basically switched off when you install it at Mac versions.
