    Hi,
    I'm looking for ways to reduce device power usage with the AR camera running. We have a AR setup where image is viewed remotely and camera and depth textures are fetched via XRCpuImages. I would like to know if it would be possible to save some power by not creating AR textures on the GPU side. Is that part done by the ARfoundation or is it already done on the ARCore / ARKit level?

    Current setup has only the camera and arocclusionmanager enabled, but the power draw is pretty high. Lowering the framerate is not really option with the AR.

    Is there any other tricks to save power with AR setup?

    Tip from the team:

    AR camera capture and rendering is optimized for GPU rendering.


    Copying camera data from the GPU to CPU is expensive.
