hmm, I only yesterday updated my Bela/Salts to the latest software, and not had a chance to test.
Were you running Orac before you updated the software? are you sure its deteriorated?
unfortunately I didn't really take any measurements of what the load was on the previous version of bela software,
so I cannot say if the number you mention are worst or not.
I'll give a go when I get a chance, but Im not sure they'll be anything I can do to improve it...
as Ive mentioned on other threads, really its down to poor floating point performance on the BeagleBone Black (due to using VFPLite) ... and so libpd is not performing well (and I cannot optimise libpd) for large/complex pd patches like Orac - this is why the BeagleBone AI is really exciting to me ๐
but as i said, when I get a chance, I'll take a look see if something odd is going on...
