The periodic delay that suddenly drops from 300 frames to 30 frames

Hi All
I was just writing a PlayerController script in a simple blank scene, but as I moved around, the periodic latency suddenly dropped from 300 frames to 30 frames, and I wondered what was causing it

Below is a screenshot of the runtime from the Profiler and urp report, I don’t know if it was caused by it

Uh, that’s odd looking. Did you check Timeline view to see what else might’ve gone on on other threads? Maybe Garbage Collection was triggered on a thread and did it’s StopTheWorld GC thing
