Title: Theater View Very High CPU
Post by: blgentry on April 30, 2017, 11:03:24 am

I've been working a bunch with Theater View on Mac recently.  I noticed that my fans turn on while I'm browsing in Theater View.  I opened the Activity Monitor and saw that CPU utilization is at roughly 300% for the Media Center 22 process.  This means it's full utilizing 3 cores of my processor.  It's clearly enough to tax the system and turn the fans on.  This is a 4.0 GHz quad core i7.  I'd think that would be enough power to run Theater View in a normal way.  It's very snappy and responsive in Theater View; very nice to use.  It's just that it's consuming so much CPU time.

My JMark on this machine is:  JRMark (version 22.0.102): 4431

When I eventually move this Theater system to a Mac mini, I don't think I'll have as much CPU power as this machine I'm testing on.  I'm unsure what will happen if MC "needs" this much CPU power in Theater View on a lesser powered machine.

Edited to add:

When playing a full bandwidth H.264 1080p video (bluray rip), MC's CPU utilization is between 45 and 55%.  Just as a data point.

Thanks for reading.

Brian.

What graphics card do you have in that machine?
Only thing i have access to is a Mac Book with intel graphics, and I don't really recall seeing that behavior there, but I'll double check.

A 2014 27" iMac?

Hendrick,

You are correct!  That's my current desktop system.  I'm experimenting with Theater View there to see if it's feasible to use a Mac as an MC based HTPC.  If so, I'll be buying some form of Mac Mini to use for that purpose.

I suppose that also means that I need to be sure that the GPU in whatever Mac mini I buy works correctly with MC for Mac.  Hmm.  I'm extremely reluctant to run Windows on anything, but maybe, just maybe I'll end up running Windows 7 on a compact form factor PC as an HTPC.  But I'd really rather do it all on a Mac if I can.

Thanks,

Brian.

I did some improvements that seemed to reduce the CPU usage quite a bit here, but its still a bit higher then I thought it should be, but maybe thats my MacBook just being slow. We'll see how it works out in the next build.

Looking forward to the next build!  I'll be testing it as soon as it's availabe.

Thanks Hendrik.  :)

FYI...

I'm running at ~80% CPU utilization when using Theater View on a MacBook Pro. I too will check again with the next release.
