Hello,

I am working on a project to display a volume render from DICOM files. Currently the render is around 60 fps on PC inside Unity Editor but I get around 10 fps on Hololens 2. I was wondering if there are any techniques to get better performance on Hololens 2. Do I have to use something like Azure Remote Rendering for this purpose or can I accomplish this without remote rendering by using some optimization on the volume rendering shader that I am using.

Currently using the volume rendering shader on this project: https://github.com/mlavik1/UnityVolumeRendering
I added empty space skipping and reduced maximum number of raycast steps but could not get a stable 30 fps yet.

Thank you
