I have upgraded my original music production PC to a Ryzen 1800x based machine (with 32Gb of RAM). One thing I have noticed while using the PC Ableton Live v9.7.2 64bit is that it only seems to make use of 8 of the 16 available logical cores on that processor. Is there a way to get Ableton Live to notice the extra cores or do you think it's hardwired that way?

"A logical core is more of a programming abstraction than an actual physical entity…

two logical cores within one physical core cannot truly operate in parallel with respect to each other. This is because HT works by having one logical core operate while the other logical core is waiting and has nothing to do
…
Well then how can these logical cores be considered in parallel? Well most of the time they can be because during typical CPU operation you will almost never see continuous execution of a single thread on every clock cycle - there are always gaps when one logical core is waiting for something and the second logical core can kick in and do its job.

BTW - in trying to stress test the machine with a large number of tracks + instruments it hardly broke into a sweat unlike the original PC!
