Hi Robert, Thanks for your reply very much.
I used osgParticle::PrecipitationEffect to render the rain and snow in my application. And I found the problem. Then I run the osgparticle example directly to test. I did not modify osgparticle. The problem seems to be solved after I update driver of my ATI mobility radeon X1600 just now.
