Macbook (Sonoma) Problem
EnglishTiger:
rito & blgentry it looks like the Architecture of your Laptops is having some detrimental impact on the CPU usage because I am consistently getting lower results on my M1 Mac-Mini.
I've even found some MC Configurations that consistently use less than 10% of the CPU - https://yabb.jriver.com/interact/index.php/topic,137111.0.htm

My laptop that I tested on is an M1 MacBook Pro. If you haven't run a test recently, you should.
Note about my testing: I do NOT look at total CPU utilization. I look at CPU used by the MediaCenter process, as listed in the big window in Activity Monitor.
The total CPU used by all programs on the entire system, as reported at the bottom of the Activity Monitor window, will be much smaller because it takes into account all 8 CPUs and averages everything. My numbers are the real CPU consumed by MediaCenter. I'm attaching a screen shot showing MC31.0.065 playing in standard view without spectrum analyzer.
Thanks,
Brian.

The images were taken between 04:18 am and 06:00 am UK Time today - Thursday 05th October. The 1st, 3rd and 5th images are screenshots of the Mac Activity Monitor and show that the numbers I quoted were the CPU and GPU values for MC31. In both reports the values were those the Mac Activity Monitor was showing for MC31, the only time I mentioned any values that appear at the bottom of it's window was to mention that on a couple of occasions I spotted that "User" was using less of the CPU than "System" something that amused me since MC31 wasn't the only app/task included in the figures for "User".
Those reports were compiled by summarising the data I had collected from over 3 hours of continuous testing on both days.

I think there is something off when running with Ventura. I'm still working on narrowing the field.
On Catalina on my 2014 Macbook pro retina CPU usage is quite low with the 30.0.65 beta.
Using about 2/3rd's of the screen 5.0% playing without spectrum analyzer. 11% playing with spectrum analyzer.
On my M1 mini with Monterey 4k monitor about 2/3rds of the screen 6-9% playing without the spectrum analyzer 16-20% playing with the spectrum analyzer.
This seems reasonable compared to the 2014 Macbook Pro since it's using a lot more pixels.
On the same M1 mini as above with a fresh install of Ventura, around 5% playing without the spectrum analyzer and 22% with.
On an identical M1 mini with Sonoma 4k monitor about 2/3rds of the screen 16-19% playing without the spectrum analyzer around 50% playing with the spectrum analyzer.
None of these are using DSP which of course would add to the CPU usage.
I need to try to test with intel vs arm and with Sonoma too.
Edit: corrected the entries and added one.
The bottom line is that something is going on with Sonoma which makes it use a lot more cpu with MC.

It sounds like you understand the difference. Thank you for clarifying that. There are no screen shots attached to your post, but that's ok because I believe your numbers and I now understand that you are quoting the same source as I am.
I'm using Sonoma; what OS are you using? I ask because of Bob's statements about the OS making a difference in his testing.
Take care,
Brian.
