Hi,
This plugin Forces alien drones to ragdoll and gibs underheavy load for perf reasons.
About:
I had a problem with the default game of handling alot of alien deaths I mean 100s clients would either endup @10fps or crash due to particles the game does not manage limited on the amount of effects shown to clients, this fixes that by default and can now play at an expectable framerate with 100s of aliens.
Problem with forcing ragdolls
Using cvar "rd_alien_instagib 1" helped with perf but removed ragdolls
but blowing up 100aliens could a crash.
I can't show an image of a particle crash because it crashes 
This will help alot with particle crashes with 100s of aliens but will not prevent them because other factors in gameplay.
There is cvars to playwith to change however you like.
For local hosting:
Cvars: swarm_drone_force_ragdoll.cfg auto created when plugin is loaded.
