    I'm trying to improve the performance of my app. There are ~42ms peaks in the GI statistics for Input Lighting Time. What does that mean?

    I'm having the same issue. Input Lighting averages about 0.02 ms typically and then has spikes up to 41ms. This is with LWRP on 2019.2.8.

    This is from the Realtime GI system, when one or more dynamic lights, emission or environment change. Disable realtime GI if you don't need it or reduce the amount of changes happening in a given frame.
