Hello again, Sorry, I thought this was put to bed too but the issues have re-occurred.
I have been having issues where i would start a video file and the audio will start but the video never does and im stuck listening to the movie/episode and looking at the menu screen only it has hung so i cant stop it from playing or anything else.
So i tried updating the SVN build a few times to see if it fixes the issue. Not sure if it has as it is random but what is now happening is the CPU usage now seems about the same no matter what i set in the driver for vsync or in xbmc for vsync. It always seems very low in the menu screen which is great but now all videos tear no matter what i do. The only way i have been able to stop the tearing is by turning "flipping" back on but then the cpu rockets to 100% when in the menus or pausing video, but is about 40% CPU usage when playing 720P content which is much lower than when flipping was off and only using vsync.
Even when my CPU utilisation was perfect when not using flipping and using vsync i could always see quality loss in video playback but not enough that it was affecting the viewing experiance to keep barking up this tree but now after this issue with the tearing no matter what i do, i can see again how much better the video playback is with flipping on. It is perfect video playback.
I think that condeming the nvida flipping option to an option that should be disabled is reducing the potential of XBMC in linux. Flipping is clearly a very good thing for watching video. The fact that it causes CPU problems in the XBMC menu and not video playback says to me there is an issue that needs to be addressed with the interface/menu not the NVIDIA driver option.
As a work around, could there be an option for flipping in XBMC like there is for vsync such as:
Flipping: Enabled , Disabled, Enabled when in Video Only
the "Enabled when in Video Only" would be the work around.
Flipping can be enabled from the driver with out the need to reload the X session same as vsync.
With flipping on, it vsync does not become an issue in video, whether it is on or off the video is perfect.
I am so supprised that no one else sees the quality difference when flipping is on. Im sure i cant be the only one? Maybe i watch too much TV/Movies and have "an eye" for quality. Maybe it is something that is unique to my setup/equipment. One thing it is not, is my imagination.
Sorry if i sound aggressive/pedantic I am just being frank in hope to help the development of this wonderful product. I have loved XBMC for over 5 years!
