Very odd. Maybe that's when it decides to use full-precision shaders (for the reflections on the plane)?
i did a little bit of research on the lens flare effect. they have a lot to do with alpha blending 2D textures and in this case the lens flares can occupy the screen to quite a large portion, perhaps fx5200 is not too good at doing heavy alpha blending work like this? but you are getting 30-50 everywhere else that is a bit strange. my fx5800 cant even get 30ish average fps but doesnt do so bad on the sun..... strange.

because your geforce 3 dont support some of the demo features? hence it should not compare validly with cards that do all intended work in demo?
