[Solved] x64 - slow video performence?

daf666 · 2009-06-29 17:51:44

Hi all;

I have been using i686 for more than two years, and on my current machine, more than 6 months, two weeks ago I moved on to x64.
It seems that video playing is slow, and even stop for half a second when the video is busy.
I am using Nvidia, and never had this problem in i686.
This is very easy to detect if playing 3 videos in VLC, please if any1 is using x64 with Nvidia, do this test: open 4 VLC windows that play the same video file (on my machine this is impossible, the fourth one will not even open)

Thanks

Do you experience slowness in mplayer? I gave up using VLC because on some video files it is slower than mplayer for unknown reason.

Same deal with mplayer and xine...

I got up to 8 instances of vlc all playing the same file (plus the telly playing in VDR) before the cacophony got too irritating. All of the vlc's were playing the video at the correct speed :-P

Woh azleifel, thank you very much for this input!!, now I know that its something with my setup..I just need to figure out what.. (not that I made any customization..)

FYI: I haven't fiddled with vlc's settings, so audio and video output are just set to "Default" (though I normally have it set to only allow one instance ;-) Similarly, I haven't touched nvidia-settings and my xorg.conf is not so complicated:

Section "Screen"
        Identifier      "Default Screen"
        Device          "GeForce 8500 GT"
        Monitor         "Acer P223W"
        DefaultDepth    24
        Option          "NoLogo" "True"
        Option          "UseDisplayDevice" "DFP"
        Option          "TripleBuffer" "True"
        Option          "DynamicTwinView" "False"
        Option          "RandRRotation" "True"
        Option          "UseEdidDpi" "False"
        Option          "DPI" "96 x 96"
        SubSection      "Display"
                Viewport  0 0
                Depth     24
        EndSubSection
EndSection

but glxgears always reports > 3,700 fps running compiz. I am wondering whether the slowdown is anything to do with the nvidia driver. What else might cause vlc to pause while reading a file?

@azleifel: I have tried your settings, and lots of others.. none seem to affect it.. 3 videos playing = system crawling

does your graphics card share its ram with main ram?

I dont think so... again, in I686 everything was perfect.. 10 videos playing without sweat.

Ok, finally.., it seems that after using azleifel settings AND choosing opengl as video output in VLC, I can open as many video windows as I want.. thanks to all.

Good for you In the meantime, I've had to downgrade to nvidia 180.60 because 185.18.14 was causing random system freezes...
