it start to feel perfect for my particular effects .
actually i did a new test, now i tried how easy it is to touch the instances with mouse… as next i will bring some self collisions in. this thing is going to boost my effects hopefully.
at the moment im using for performance boosts at my particle effects:
rastering, time delays and this method…
im running out of ideas, where to win any better performance anymore.
