I hesitated a while to register and post this issue if it's really an issue, but because I got no answer for it finally I created this post.
Process Hacker, also older versions (and the nightly build) displays a global 20-30% CPU load while the system is idle, IN THE CIRCUMSTANCES when other free and commercial system monitoring application display 0-4% usage. The other system monitoring software which I used to check this are: Aida64, HwMonitor from CPUID, the Task Manager from Windows, CPU load gadget in Windows, Wise System Monitor, and another commercial software.
Only very old versions of Process Hacker displays 0-4%. Why is this?
I'm running Windows 7 Home Premium 64-bit.
