Hello,I read some threads about using a geometry shader to cull vertices that are not inside a view frustum,however I can't find a basic explanation or tutorial of how to set it up anywhere.I can't find it in the SDK examples either.Anyone have a source for a tutorial or demonstration of it?Is it really faster than CPU culling,cause the other culling method,that actualy was in the sdk(DrawPredicated) ran slower with the feature turned on than when not culling.

yeah I checked that one out,but I was interested in learning about this whole output stream business,which doesn't seem to be covered in tutorial 13
