Odd slow fade with real time lights

Graphics Lighting & Global Illumination
1

I have a real-time point light in the scene that I turn on and off with a key press. When I turned on Linear Color Spacing and HDR, and I started noticing a strange effect on the point light. It fades off from the camera. I do not why there is a slow fade that fades away from the camera. To see what I mean, I have a short 10 second clip.

Can someone explain this? Do I just have a slow computer?

You’re using realtime precomputed GI, yes? Unity’s realtime GI doesn’t update instantaneously, so if a light changes rapidly you may need to set that light’s bounce intensity to zero to disable real time GI for that light, or increase the realtime GI’s CPU usage.

Thank you.
