Pro Tools not maxing out CPU?
 

I just realized, that PT doesn't seem to take advantage of the available CPU power efficiently.
During an offline bounce the overall system CPU consumption didn't exceed 60%, while the bounce would have benefit from higher usage as it only went with 2.7x.

A video export with Adobe Premiere does a much better job in utilizing the CPU.

Anybody have an idea why PT leaves nearly half of the available power unused?

Meads, I always thought that the 2.7x was the percentage of the bounce that is happening faster than realtime....

Is that what you understood? So 2.7x faster than realtime bounce.

Re: Pro Tools not maxing out CPU?
 

Yeah, that's how I read it. But why not using 40% more CPU and going up to like 3.7x faster than real time? Why is there this cap?

Re: Pro Tools not maxing out CPU?
 

Oh, I see now...I didn't understand what the top percentage gauge was doing.

Well it looks like it needs to be optimized for sure

Oh, I should have made it more clear, sorry. Edited the original post.

It's 2020. My i9 CPU usage is around 30% when offline bouncing. Why not use 3 times as much? Wondering if it's dependent on Pro Tools, plugins in use, BIOS settings or something else...

It's software. It's complicated. It just can't go magically use free CPU. Lots of things running during a bounce are single threaded.The overall utilization should change significantly for different sessions. For how deep plugins are chained, what exact plugins and how many instances of them you have.

Thanks Darryl.

Interesting! I am aware of the SingleThread bottleneck, but still I was puzzled why not a single core hits 100% during bounce or playback.

In my recent session, the most utilized core hits 20% during bounce and other 7 cores are barely coming close to that number.

And yes I optimized my machine (AMD, Windows) like a swiss watch.

So yes, it was good to hear any kind of confirm on this topic. Thanks.

A couple of things to remember:
1-the cpu usage metering in Pro Tools is sketchy at best.
2-the speed of a bounce to disk can vary widely depending on what plugins are in use. And Instrument plugins can drag things down to a crawl(so using Track Commit for VI tracks is a good idea, once midi is all good).

Offline bounce still needs to honor the routing of your mixer. If one plugin is a bottleneck somewhere something like this is expected.
