During use beta i checked it as well at whole host performance thru popular test from ableton forum (It's can be grab here https://forum.ableton.com/viewtopic.php?f=1&t=191549 ) My result was the same as in v9, not bigger.musikmachine wrote: Btw a few people on the ableton forums are saying 10 is killing their CPUs in comparison to 9...
The only thing, when i tried scroll by mouse horizontal time bar during playback test projecti i can noticed little rare cpu spikes, it was similar to increased loading from video component (due to UI engine, someting like that). In v9 i could not reproduce that effect. But I do not consider this important. And again, it was beta, maybe something has changed.
Added: oh i see problem for download test zip now (404), so i attach original file for just in case
