Re: CPU usage in Live 10

has anyone already mentioned integrated graphics card versus dedicated graphics card? Live 10 defaults at integrated meaning it uses CPU cycles. that's better for you battery but will not be giving you the best CPU performance. it's a compromise between efficiency and power. if you want better performance make sure your dedicated (GPU) graphics cards is used when using Live. I am using the donation ware tool gfxCardStatus on my MacBook Pro for this.

...or you could just switch off graphic cards switching within os preferences...no need for a tool...

As we are talking about a relatively simple 2D GUI here, the difference should be negligible (and is) unless there's something wrong with the system. Always test to failure instead of seeing a number on a CPU monitor; build a stress test project in Live and see how many plugin instances you can run, of the plugins you usually use. Find where the limit is when you start hearing audio breakups. Do the same with the dedicated adapter and the built-in graphics. Unless there's something funky going on with the drivers, power saving or whatever, you will find that there isn't really a meaningful difference there.

Hi folks,

I think there's something wrong with Ableton. The first few seconds after startup, Ableton is stable (CPU around 1-10%). After some time on, the CPU will jumping 92,15,75,64,85,37 ... and the sound will start cracking when playing.
OK I did the test. I have two of the same songs, one created in Ableton and the other created in the Reaper. Same instruments, same samples, same effects. In Reaper the song is pure, CPU indicator 0.2-3%, max.6% sometime. In Ableton after a few seconds jumping the CPU indicator (30-80 ...) and cracking the sound.

I do not understand that. I noticed Ableton loading my GTX1080 GPU (30-40%). Why?

Win10, i7 4790k, 16GB RAM, GTX1080 and GTX1070
I found one interesting thing. On my older laptop (Dell Inspiron N5110, i5 processor), Ableton works well with a stable CPU load, no cracking and other annoyances.

Very interesting..
