CPU usage in taskmanager & Renoise

System CPU usage is not Renoise CPU usage:Renoise only shows CPU usage of what it reserved for its audio thread which is only partially of the full CPU and also depends on which core is used for what.

I’m sorry but I don’t think I understand. So renoise can show 100% of cpu usage while system’s cpu usage display 40% ??

PS: I have set ‘multicore/cpu support’ to 8CPUs so logically thinking it should display the same percentage of cpu usage…

Taktik tried to explain this somehow:

Also try this for multi-core explanation:

Note that the HT non-support only counts for the old Intel with 2 or 4 virtual cores that were available back in those days, the newer HT cpu’s are supported.

Ok I got it, thanks : )
