Thank you for your reply as this:

>textures, how big are the textures, what format are the textures etc
>But your biggest problem is your using an integrated chip set See this FAQ
>Integrated graphics chipsets do not perform well with OpenGL and thus OSG,
>especially older chip sets and those that use system memory and not
>dedicated memory, even newer modern chipset versions are still very poor and
>slow compared to a dedicated graphics card
>About the only advice I can offer is Google for updated graphics drivers,
>this may or may not help.
I am sorry to say that in my letter before,i just made a mistake.My model is 60M size , not 6M.And I just want to know what is the problem with slow frame rate? Is the frame rate( 6 ) normal to 60M's model? All of the textures (png format) are in the ive file(60M size). Is the triangles number critical to this problem?

Recently, i have some problems about slow frame rate. My test model (ive file) is about 6M size.My test computer's configure is follow:
Celeron D CPU 3.06GHZ single core
integrated graphics card： Intel(R) 82945G Express Chipset Family
I use the osg2.6's osgviewer and osgviewerMFC(muti-thread) release exe to test in WindowXP.
In attachment,there are two pictures:
1.scene.jpg(my model's scene graph organization)
2.frame rate test.jpg(my test result)
The frame rate is only 6.. ,i don't know if it is normal,anyone can help me?
