Hi all, I've also experienced a delay issue when using osgPPU combined with Delta3D.
All the examples (like the glow) which requires 2 different paths and a final unit combining them, show an offset of at least one frame between the 2 rendering paths. Delta3D should not interfere here, as it leaves all the rendering part to osgViewer. Any hint on the possible cause?
