Spawning more Models on maps

I find that spawning to many models on maps result in hiden models or defect models when considering mgs...
Is there a way to increase the amount of spawnable models per map without getting unsatisfying results ?

I wouldn't think so. I know that when you spawn 411 care-packages it crashes, with no lag, but that is like when nobody is on, just a pvt match.

Don't think so unless you feel like coding it your self
