Stuttering, Nsight profiling, and insanity

Hi all. Today I am trying to diagnose a system issue. The system is presenting with high stutters (900% delta) whenever a new entity is rendered. To facilitate this test. I ran a profile on Dota 2 in demo mode, and spawned in units by clicking a button. Every time a unit is spawned, the frame stutters present themselves. I’ll attach the qdrep file here. I’m not entirely sure what is causing the stutter as this is my first foray into profiling. But I hope I can nail down the root cause with some help!

I begin to press the spawn button at ~ 30 seconds. The frame durations seem to get increasingly longer as more units are spawned

Would still very much appreciate help with this issue
