[quote="abr"]This is not necessarily the fault of the progress bars, since Opus most likely uses standard Windows-APIs to view the progress bars.
Maybe it also depends on the stuff you copy. Please have a look in this thread:

Thanks for the link
But for my problem, if i desactivate "Show progress bar speed timers when copying from or to" it uses almost no cpu .. so i think it's really the speed of refresh of the nice progress indicators window that causes high cpu
