Question @Nvidia: OpenGL apps with compiz enabled run slower

Hi,

I have done some testing with quake4 multiplayer Demo "playNetTimeDemo id_demo.ndmo86" and latest compiz svn.

My results are:
driver version | NVIDIA-Linux-x86-100.14.11
resolution | 1280x720

metacity | 99 fps
compiz | 84 fps (it never looks as smooth as without compiz)

A part of my xorg.conf:
Code:
Section "Device"
    Identifier     "Geforce 8600 GT"
    Driver         "nvidia"
EndSection

Section "Screen"
    Identifier     "Default Screen"
    Device         "Geforce 8600 GT"
    Monitor        "BenQ FP231W"
    DefaultDepth    24
    Option         "DisableGLXRootClipping" "true"
    Option         "RenderAccel" "True"
    Option         "AllowGLXWithComposite" "True"
    Option         "AddARGBGLXVisuals" "True"
    SubSection     "Display"
        Depth       1
        Modes      "1920x1200" "1440x900" "1280x800" "1280x1024" "1280x800" "1024x768" "800x600" "640x480"
    EndSubSection
    SubSection     "Display"
        Depth       4
        Modes      "1920x1200" "1440x900" "1280x800" "1280x1024" "1280x800" "1024x768" "800x600" "640x480"
    EndSubSection
    SubSection     "Display"
        Depth       8
        Modes      "1920x1200" "1440x900" "1280x800" "1280x1024" "1280x800" "1024x768" "800x600" "640x480"
    EndSubSection
    SubSection     "Display"
        Depth       15
        Modes      "1920x1200" "1440x900" "1280x800" "1280x1024" "1280x800" "1024x768" "800x600" "640x480"
    EndSubSection
    SubSection     "Display"
        Depth       16
        Modes      "1920x1200" "1440x900" "1280x800" "1280x1024" "1280x800" "1024x768" "800x600" "640x480"
    EndSubSection
    SubSection     "Display"
        Depth       24
        Modes      "1920x1200" "1440x900" "1280x800" "1280x1024" "1280x800" "1024x768" "800x600" "640x480"
    EndSubSection
EndSection

Section "Extensions"
    Option         "Composite" "Enable"
EndSection
So I would like to know is this a driver issue or a problem with compiz?
If it is a problem with compiz, are you working together with the compiz developer (for example David Reveman) to improve this situation?
