Ableton Forum

The CPU meter tells you how close Live is to miss an audio deadline. It's not saying you're using too much CPU or that you don't have any headroom left. If you add more tracks, more plugins but they can run in parallel with the heaviest workload responsible for the CPU meter current value, then they ...

The GPU acceleration in Live 11 and Live 12 both target Metal V2 to be as widely compatible as possible.

As each application is programmed differently, I can't really say if testing with Logic Pro or Reaper gives you an adequate comparison point. Are you sure they do GPU rendering to the extent ...

This was a multi-year effort. The 12.2 beta will see refinements / optimizations as we get feedback and do more real world testing!

Please let us know your experience both neutral, positive or negative and in particular on which GPU hardware. There is so much GPU hardware out there.

Just a little ...

Maybe somehow the project is on some drive / filesystem that does not support the trash?

Similar problems here on a Win11 machine with plenty of RAM. Getting CPU spikes and audio drop outs in Ableton. Only really started in the past week or so.


I haven't received any trace from the original poster, I could have a look at yours. Can you follow the steps in my post here? https ...

With no tuning system installed, does applying MPE pitch bend works with the Arturia Pigments patches you're using? The tuning system feature works with MPE pitch bend (with default range of +/- 48 semitones)

I haven't used Arturia Pigments myself so I cannot guide you there, but maybe it needs ...

I'm having serious issues since installing Live 12.

1. The CPU overload indicator in Live keeps lighting up with even with like 4/5 stock Ableton plugins running and Ableton effects. Average % is around 35% which is insane. I could easily run 30 channels with 3rd party plugins from the likes of ...

Hi,

M1,2,3 apple silicon chips today have an architecture composed of performance and efficiency cores. This was known in the past as a big.LITTLE architecture and did not exist on personal computers, only mobile phones. Nowadays it's both on Mac and PC with Intel's latest offerings as well.

This ...

Thanks for the collaboration offer!

About the trace: From the trace only I cannot yet know whether / how much the coordination work is useful or wasteful. This depends on your set and how tracks and audio flow into one another. So ideally we would need to have the set as well to inspect the signal ...

It is not the expected experience with Live, I believe you just encountered a defect that was unfortunately introduced in 11.3. A fix is upcoming (it's in beta)

(Drawing data and analysis is stored in .asd files that Live creates)

Thanks for trying the MaxAudioThreads settings!

I wouldn't try without SMT at this point, it seems more trouble than its worth.

Before disabling SMT, try playing with the Options.txt's -MaxAudioThreads=32 and see if lowering it to 16, 8 helps out.

What I see at first glance in the .etl trace is that Live's engine is trying to parallelize as much as possible but the cost of coordinating so many threads appears quite large ...

I am sry, that was a bit too optimistic, the smaller dropouts are still there,
but CPU load dropped for about 3 percent by the measures taken so far.


On the CPU meter, if you toggle "Warn on CPU overload" the indicator next to it will light up when Live has noticed a dropout. Is it toggled? Do ...

Hi,

I would be curious if you could try setting in your Options.txt the MaxAudioThreads variable, to limit the number of concurrent audio threads, for instance:


-MaxAudioThreads=32


On your machine with SMT at the moment Live will by default allocate a large amount of threads, around 64, which ...

not really, SID files contain a computer program that is meant to run on a C64. There is no note data there, only instructions for the 6502 cpu that will drive a SID chip.
