Maybe you are right, I dunno, but it could be in the event server. But to consider what triggers the explosions animation, its safe to say that it won't that harmful to the server, I mean most of the stuff the troopers use doesn't have the animation, for example the launchers don't have the new particle, the bowcaster has it, but not many people use the bowcaster, right now the main concern is the helicopter grenades, which they trigger the particle to show up, I am trying almost everything that we use on the server, and I tested it with around 30 helicopter grenades near eachother, with a lot of npcs on the map to see if the fps drops are too much, which on my case proved to not cause fps drops, rathen than the npcs lowering my framerate. I don't know with what you tested the addon with, but for me it works fine
I tested this, but I don't know if I am near to being right or totally wrong:
In this my FPS kept at 22:

After I placed some grenades in the middle of the NPCs, it dropped my framerate, because of the conflict I think with the npc and the grenades. I don't think the conflict between the players and the bombs would be that harsh, unlike the npcs and bombs

Then I tried only bombs at one place:

And my FPS kept from 42 to 45, before and after the explosions

Tried placing as many of them as I can, and my fps didn't go down
I don't really know if it's my computer or stuff like that, but it seems fine for me.
