Big difference in Live CPU bar usage,same setup,2 laptops
Posted: Sun Jun 07, 2015 5:19 pm
I have Ableton Live 9 suite running on 2 computers, same VST there, Omnisphere, Kontakt. on using exactly the same instrument in the same Live Set, I have:
- laptop sony vaio i3, 6gb RAM, windows7, 15% ableton bar CPU usage
- laptop dell inspiron i7, 8gb RAM, windows8, 40% ableton bar CPU usage
remember, same ableton, same live set, same vst instrument etc
tested this with 2 different sound cards, the 'better' laptop has higher cpu usage with both, so it's not a sound card issue. both windows are set-up the same, for performance... and optimized
don't tell me it's windows8...
to avoid any confusion: in my windows task manager all is going well, CPU is ok and not spiked at the least on the dell laptop, usage is about 10%....
what I was talking about was the CPU usage meter inside Ableton Live, that bar that fills up with yellow in the right hand corner. that is 40% ! while in task manager, dell laptop, my cpu usage is 10%
used same buffer and audio card (focusrite) on both...
then I made a live set with 10-12 tracsk with vst instruments
dell: cpu 2.2ghz with 8 cores, 20-25% in windows task manager, around 100% in ableton metering cpu bar. even got over and some crackles
sony vaio: cpu 2.4ghz, 4 cores, around 25-30 in windows task manager, around 75-80% in ableton metering bar, holding up
in a bigger nr. of tracks differences tend to be less big, but still more than large to affect performance. also, if ableton is multicore and spreads processor power better on more tracks rather than few, why does the 4 core system win out with such a considerable difference in its favor?
conclusion: in windows task manager about the same, in ableton different ball game.
is there someone from ableton around here to clear this up maybe? or should I just try with windows7 and think that you need less cores for ableton performance?
any ideas, please?
