dual depth peeling slow with high number of actors
I want to display a big model (800'000 triangles) with translucency.
I have 2 configurations :
A - the model is a single actor.
B - the model split into 500 actors.
Without dual depth peeling,(ren.SetUseDepthPeeling(0)) so using the classic alpha blending, rotating the model in the view is fast in both configurations.
But if I activate dual depth peeling, the configuration B is slow (CPU bounded).
I attached a session file to reproduce the issue :
Just play with the two boolean at the beginning of the file.
