--- Comment #120 from Mahendra Tallur <ma...@free.fr> --- Hi again, I would like to raise a different but likely connected issue : on my setup, either setting USLEEP or triple buffering does fix the tearing issue. With either, performance is wonderful in 3D games (1060 GTX + i3 CPU). However, what boggles me is the responsiveness and smoothness of kwin itself (I mean the desktop : resizing windows, raising menus etc.) is inconsistent. The same animation can be butter smooth then the next time appears jerky. It's actually always happened as long as I can remember when using kwin and Nvidia cards. It seems slightly better with triple buffer, but as I don't want to add input lag in games... I kinda supposed it was a standard behaviour, but I noticed that even old machines with Intel HD Graphics would show a perfectly constant 60 FPS in kwin. I tried to remove my Nvidia and use the built-in Intel HD and the desktop felt perfect. It even seemed to feel smoother with the Nouveau driver. I'm pretty sure all this is also related to the difficulty to work with the proprietary driver. As you devs are aware of the vsync issue, what's your opinion on the "desktop smoothness" issue ? Thanks again :-) Best regards & happy new year :) -- You are receiving this mail because: You are watching all bug changes.
