What is all being sent to the OcclusionSubmittedFence and why does it slowly kill my scene?
I’m in the process of testing optimization of lighting and particle systems and I’ve finally figured out the culprit of what has been slowly killing my scene the longer I have it open (sort of). The only noticeable change I can find in my scene data is the OcclusionSubmittedFence Wait slowly takes up more and more ms in the scene.
Some background info:
All the lights are Dynamic and RayTraced.
I’ve checked all my particle systems and they are all setup properly to remove particles after lifetime. I’ve also confirmed through **stat Niagara **that my particle count is stable.
The only movement happening the scene are the lights which are set to slightly wiggle to better emulate the fire effect.
The fog in the scene is setup through a particle system with a material that uses SphereMask in its material.
