What happend when render-query result time cost high?

Hi All
I have question about render-query.

I tested some my scene. Using Console Command “Stat SceneRendering”, found RenderQuery Result time is very high, AVG 5ms, FPS about 75~80FPS.

When I limit lower FPS(70FPS), it cost much fewer, almost ~0ms.

Is that mean GPU have too heavy job? If so, that’s mean RenderQuery Result indicate the GPU total power capacity?

Can someone tell me, that’s relationship is correct?

THANKS

Did you ever figure this out? Have the same issue.
