Hey there @MrTNT16! It depends how fast we’re talking. Primarily the only things in the view frustum will be rendered, this is determined by a bounds system. If the projectiles are large or slower, just increasing the objects bounds could mitigate this without too much performance hit. However this can be a bit more tricky with fast moving small objects.
So if you’re doing something like physical small fast moving bullets, this won’t really be so effective, but give it a try!
