--- Comment #131 from Marcin Ciosek <presid...@people.pl> --- My system is Optimus based laptop (Intel HD4600 and nVidia GTX 860). I don't use Bumblebee but prime-switch feature. The high cpu load during file operations notification progress (the wheel is spinning like crazy!!) is showing only while using nVidia card. If I switch to Intel - no cpu load issue - the wheel is spinning slow. -- You are receiving this mail because: You are watching all bug changes.
