Femto Bolt tips to reduce latency?

I’m looking for any suggestions to minimize the latency of captured images on Femto Bolt. I’m using the k4a wrapper functions to capture 1080P BGRA32 color images, and NFOV_UNBINNED depth images. The latency seems slightly worse than on an old Kinect2. I’m hoping for equal or better…
I’ve tried config.synchronized_images_only = false; but that doesn’t seem to change anything: the color and depth images still arrive in the same capture.
I don’t want any image post processing, how can I confirm that is disabled?
Is there a way to move any local cpu processing onto the gpu?
Thanks for any ideas!
