Default xorg.conf needed option to maximize compiz performance.

Hi,
I'm using Fedora 8 on an Acer Aspire 5920G Gemstone using 8600M GT
with 100.14.19 driver.

here my xorg.xonf

Code:
# nvidia-xconfig: X configuration file generated by nvidia-xconfig
# nvidia-xconfig:  version 1.0  (buildmeister@builder26)  Wed Sep 12 14:29:17 PDT 2007

# Xorg configuration created by pyxf86config

Section "ServerLayout"
    Identifier     "Default Layout"

    InputDevice    "Synaptics" "CorePointer"
EndSection

EndSection

Section "Screen"
    Identifier     "Screen0"
    Device         "Videocard0"
    Monitor        "Monitor0"
    DefaultDepth    24
    SubSection     "Display"
        Viewport    0 0
        Depth       24
    Option "AddARGBGLXVisuals" "True"
    Option "DynamicTwinView" "False"
    EndSubSection
EndSection

Section "Extensions"
    Option "Composite" "Enable"
EndSection
Is there some option that I need to remove or add to maximize compiz performance?

Is this extra option useful?
Option "AddARGBVisuals" "True"
Option "RenderAccel" "1"
Option "AllowGLXWithComposite" "1"
Option "NoRenderExtension" "0"
Option "XAANoOffscreenPixmaps" "1"
Option "TripleBuffer" "true"

With my xorg.conf compiz works really fine but euphoria screesaver for example seems to slow down quite often.

Thanks!
