Yep; my early tests had indicated that it would be feasible, and so we were proceeding as if it were. However, on more extended testing it turned out there was a nonlinear expense to those sorts of swarming fighters. They absolutely wreck the performance pretty fast. So, much as I loved them, we had to ditch them. The "trail renderers" that give the curvy contrails, too.
But I did figure out a clever way to give contrail-like effects to shots that are moving, so that's a thing.
