Hello,

I am using Performer 2.0. to create three channels and a lot of pfSCS
nodes being used. Since I have three channels, culling process have to do three
times. Matrix operation of the nodes and culling process drastically slow down
the refresh rate. I would like to maintain at least 30Hz refresh rate.

To improve the refresh rate, I need to do some prefilter to advoid the
unnecessary nodes being rendered. I think this will reduce the burden of
culling process. Can you tell me what is the most efficiency way to do
prefilter? Where can I find the sample code?

Is it possible to force the culling process cull the tree once only? I
still need three channels(left and right channels have 45degree offset). If it
is possible, how to do it?

I will appreciate for your help. Have a nice day.
