Ableton 10.1 upgrade - audio issues

[bloomstaxonomymusic]

Hi all, new to the forum!

I've been using Ableton 10 since it came out to do live performances and visuals using the Zwobot VJ plugin. I never had any problems with crackles, CPU overload or anything of the sort. I updated to 10.1, and using exactly the same session files, they now have sound dropouts, crackles and all lag. The Zwobot program itself was always a bit dicey, but it would never affect the audio. I've tried deleting the config files and it hasn't helped. It doesn't matter whether I use ASIO4ALL or my interface driver. Interestingly, the CPU meter only goes up to 60% when this seems to start happening. Previously, it would happily go up to 100% with no problems. It's very frustrating - I've tried rebuilding the Zwobot track from scratch, deleting effects, folding and freezing tracks but nothing seems to be working. I have a gig coming up in two weeks, and I'm getting stressed as I'm running out of time to practice.

Any help greatly appreciated!

Update - just done various tests - tried changing the resolution/enabling HDPI/changing the sample rate and buffer/even completely deleting Zwobot from the file, still makes no difference. Even seems to be happening on old arrangement files where there were previously no problems.

Send a request to support of Live, it seems to happen more often......

I'm with the beta program. Started having severe lagging in graphics a couple of weeks ago.
To me seems to be related to Arturia V-Coll, because problem goes away when I delete tracks with them instruments.
Also found rendering/exporting master to be really slow when having more than 4-5 V-coll instruments.
So frustrating as all my project are utilising 10+ of these plugins, and now everything is slow like hell.

Did you report this on Centercode during the 10.1 beta testing?
