The CPU meter you see in Task Manager is measured directly by the system, and will always be the most accurate reading.
The CPU meter in Renoise is only measuring audio thread usage, and its accuracy can be somewhat affected by various different factors (energy saving, speedstep/turbo, etc), which you can read about here:
Just downloaded this nice synth and realized Renoise calculates very inaccurate CPU usage. According to Renoise some of presets of the synth takes up to 43% of C2Q Q8300, whereas windows tast manager shows 6-10%. CPU usage meter is inaccurate in general, not just with the synth.
Also I’ve got a suggestion an option to show per DSP track CPU usage meter in the mixer view. There is a lot space to put a couple of numbers. No mockup this time.
Also, some notes on multi-core usage:
Renoise 1.9 supports now multicore CPUs. Here is what you can expect from it and what not:
Hyperthreading CPUs of the first HT generation CPU lines are not supported.
They will be treated like single CPUs as our testing results did not show any real performance gains, or even worse: They cause a performance degrease.
Why? HT Cpus are “faked” multicore CPUs. Realtime parallel Audio processing (the way we use the multiple cores) can not really be handled by them.
The i5 and i7 and newer Intel …
