1. Wind model. My wind models are usually CPU intensive. If you need to spare your CPU, disable the wind model.
2. Number of channels. Although the rear channels disabled, Hauptwerk still takes them into the account for the wind model, for example, (for the sake of the stability and predictability). So, model with 6 channels is likely to use more CPU than 2 channel model.
3. Number of samples per rank.
Finally, there is nothing wrong in using CPU power to calculate, that is what they are manufactured for.
Thanks, Jiri, for your prompt reply. Actually, I'm not directly upset with CPU usage, which of course is made to be used, but the louder fan noise generated when the CPU is used continually at a higher level, as I use the same 2-in-1 laptop for both Hauptwerk hosting and score reading/annotating. Since I metered considerable difference in CPU usage between samplesets, I thought it could be something fixable related to the Klapmeyer sampleset, Hauptwerk itself or something between those.
Anyway, I have discovered that setting maximum CPU usage to 90% on Windows' advanced power configuration refrains CPU fan to reach its noisiest speeds while loosing only a tiny performance on other tasks.
