HDRP: Very high GPU consumtion in idle editor

Hi,

I’ve noticed that the Unity editor causes very high GPU usage (between 60% and 90%) in the following scenario:

  • HDRP render pipeline
  • Editor window open (game not running)
  • Editor completely idle (no 3d movement)
  • Visual effects stack active
  • No lightmapping or other background processes going on.

This is odd, because nothing is happening in the scene, it’s literally a static image.

What’s also interesting: if I turn off “Animated materials”, the GPU usage drops to zero, even though I don’t even have any animated materials in my scene…

Anybody else bumped into this?

Hi,

I’ve noticed similar behavior (Unity 2019.3, HDRP 7.1.6). If I have my prototype content here on screen (simplish grey-boxing stuff) often the GPU usage is around 60-75%. Editor view, camera and Inspector visible, nothing happening and I got automatic lightmap baking etc off.

Now that you mentioned animated materials option, I tried it and GPU usage drops. Good find, as I don’t want to wear out my hardware for no good reason.

Thank you! I was running into the same problem, it was often at 100% GPU usage and it was driving me nuts. Turning off animated materials in the scene view is fixed it.
