    F11 Low performance Intel X3100

    Hello,

    I have a Dell Inspiron 1525 laptop with a X3100 on board. The problem is the performance doesn't really fit my expectations. Compiz works fairly OK, but TuxRacer runs at 25 FPS, Glest runs just terribly slow and there is quite noticeable tearing in videos (MPlayer and Totem). Not to mention 400-600 FPS in glxgears.

    So far I have only tampered with Xorg (see below, changes marked red). Please, any of you guys knows how to fix this?

    Code:
    Section "ServerLayout"
    	Identifier     "X.org Configured"
    	Screen      0  "Screen0" 0 0
    	InputDevice    "Mouse0" "CorePointer"
    	InputDevice    "Keyboard0" "CoreKeyboard"
    EndSection
    
    Section "Files"
    	ModulePath   "/usr/lib64/xorg/modules"
    	FontPath     "catalogue:/etc/X11/fontpath.d"
    	FontPath     "built-ins"
    EndSection
    
    Section "Module"
    	Load  "dbe"
    	Load  "glx"
    	Load  "dri2"
    	Load  "dri"
    	Load  "record"
    	Load  "extmod"
    EndSection
    
    Section "InputDevice"
    	Identifier  "Keyboard0"
    	Driver      "kbd"
    EndSection
    
    Section "InputDevice"
    	Identifier  "Mouse0"
    	Driver      "mouse"
    	Option	    "Protocol" "auto"
    	Option	    "Device" "/dev/input/mice"
    	Option	    "ZAxisMapping" "4 5 6 7"
    EndSection
    
    Section "Monitor"
    	Identifier   "Monitor0"
    	VendorName   "Monitor Vendor"
    	ModelName    "Monitor Model"
    EndSection
    
    Section "Device"

    	EndSubSection
    	SubSection "Display"
    		Viewport   0 0
    		Depth     4
    	EndSubSection
    	SubSection "Display"
    		Viewport   0 0
    		Depth     8
    	EndSubSection
    	SubSection "Display"
    		Viewport   0 0
    		Depth     15
    	EndSubSection
    	SubSection "Display"
    		Viewport   0 0
    		Depth     16
    	EndSubSection
    	SubSection "Display"
    		Viewport   0 0
    		Depth     24
    	EndSubSection
    EndSection
    P.S. Tried all EXA/UXA/XAA and UXA gives the best results. "Tiling" "false" doesn't help.
