Hi  
I do not know if the current framerate in H2K or 1080p or 720p is limited by the camera sensor specs or by the USB3 bandwith.

If the USB bandwith is the limitation, would it be possible to have a grayscale only mode with higher framerate? It would in theory reduce the bandwith usage by 3x for those cv algos which do not require rgb info.

Thanks

The limitation is not the bandwidth. The camera streams natively a synchronized couple of RGB images in YUV422 format, no other format is provided.  
The SDK provides grayscale images, but only after SW filtering on the host.
