https://bugs.kde.org/show_bug.cgi?id=322060 --- Comment #91 from Philip Sequeira --- I had a big performance regression after the last driver update and hadn't gotten around to debugging it. I won't be on the computer with the nvidia card for another day or so, so I can't test the new one yet, but it's probably that, and not the sleeping business. usleep is still working great for me, though, as far as this issue is concerned. -- You are receiving this mail because: You are watching all bug changes.
