Progressive sampler problems

[daniel.reutersward]

Hi,

I have a problem with the progressive sampler.

Everytime I region render or use "Track mouse while rendering" the cpu utilisation drops down to somewhere between 4% and 26%?
I´ve tried several different scenes both complex and simple and the same problem occurs.
When I render a full image the cpu utilisation is at 100% all the time.

This problem only occurs when using the progressive sampler not when using adaptive.

Some system specs:
2x Xeon E5-2697 v3
64gb ram
Windows 8.1 pro 64-bit

Any help or pointers are very appreciated.

Will look into it, thanks for the pointer; I don't think there's anything particular that you can do on your end unfortunately.

Best regards,
Vlado
