Can some render processes be modified?

I am rendering a large scene with Ultrascenery and Ultrascenery is not set to show only camera view because I want to animate the camera orbiting around the subject in the middle of the scene.

Each time a new frame renders it takes about 30 minutes to:

Iray (Scene Update) : Updating LPE labels

Iray (Scene Update) : Updating geometry

Iray (Scene Update) : Retrieving geometry

Iray (Scene Update) : Updating motion transform data

Iray (Scene Update) : Updating section objects

Iray (Scene Update) : Updating materials

Iray (Scene Update) : Updating volumes

Iray (Scene Update) : Updating environment

Iray (Scene Update) : Updating lens data

Iray (Scene Update) : Updating lights

Iray (Scene Update) : Updating instance topology

Iray (Scene Update) : Updating flags

Iray (Scene Update) : Updating backplate

Iray (Scene Update) : Updating portals

Iray (Scene Update) : Updating decals

Iray (Scene Access) : Retrieving geometry

Iray (Scene Access) : Retrieving device geometry

Iray (Scene Access) : Retrieving volumes

Iray (Scene Access) : Retrieving textures

Iray (Scene Access) : Retrieving device textures

Iray (Scene Access) : Retrieving flags

Iray (Scene Access) : Retrieving device flags

Iray (Scene Access) : Retrieving lights

Iray (Scene Access) : Retrieving device lights

Iray (Scene Access) : Retrieving section objects

Iray (Scene Access) : Retrieving device section objects

Iray (Scene Access) : Retrieving materials

Iray (Scene Access) : Compiling custom code

Iray (Scene Access) : Retrieving environment

Iray (Scene Access) : Retrieving device environment

Iray (Scene Access) : Retrieving backplate

Iray (Scene Access) : Retrieving device backplate

Iray (Scene Access) : Retrieving portals

Iray (Scene Access) : Retrieving decals

Iray (Scene Access) : Retrieving device decals

Iray (Scene Access) : Retrieving motion transform data

Iray (Scene Access) : Retrieving device motion transform data

Iray (Scene Access) : Retrieving lens data

Iray (Scene Access) : Retrieving device lens data

These updates and retrievals take about a half hour to process, and it repeats this half hour process for each frame.

The only thing that is changing in the scene is the camera angle.

Then when the iterations get rendered, after those processes finish, it takes under a minute to do 500 interations.

It is not the rendering that is taking time is refreshing redundancy in the scene.

I have Daz in Iray mode, why can't the render engine just reference that data instead of recompiling it for each frame?

Am I missing something here?

And my PC sits idle, I have 24 threads and 96gb of system ram, you would think this scene could be held in system memory and only items that change could be rendered.

There should be a way to streamline this rendering process.

My scene is probably over 24gb of video memory.

It is not the render that seems to take time but the render preparation and scene redundancy.
None of the lights, materials/textures, geometry, environment... are changing in the scene, why do they need to be recompiled for each frame?
