CPU Spikes when launching scenes for the first time(s)(Live 10/11)
Posted: Thu Sep 16, 2021 7:30 am
Hi
I have a rather annoying problem with my live-performance-set. It consists of like 10 audio tracks (with mostly warped clips on pro), a Maschine 2-Instance routed to 16 audio tracks, 8 tracks with 4 u-he hive instances + 4 drumloop tracks and (finally) some tracks for clyphx actions. So something around 40 tracks. The whole set has around 150 scenes I think.
Now the problem is - when I launch some of those scenes I get a cpu spike / crackle pop when launching it for the first time (sometimes also the second time), after that the cpu spikes are gone. This is happening in scenes with and without virtual instruments playing (or changing chains). The problem seems to be the same in Live 10 and Live 11 (latest beta). It is independent of used audio interface (internal or babyface).
My system is a 2.8ghz macbook pro 15 (mid 2015). I had only 100gb of 1TB free in the first tests, but now I have 250gb free and the problem is still existent.
Anyone has an idea ?
Cheers

EDIT: I use a moderate buffer of 256 with 44.1 khz. I tried removing all stuff besides the 10 main audio stem tracks - things remain the same, cpu spikes on initial launch. I copied all content to a new directory and enabled "ram" mode (and disabled HQ) for everything
EDIT 2: It seems to be a bit better if i DISABLE RAM-Mode for all my clips. Maybe the problem is that my whole project is around 16gb in size (and I have 16gb of memory) and the systems is going to swap ram to disk. I changed to RAM the other day when I had show and the last track would not play because of "disk overload" (All stems only played the first bar and then stopped)
