  Hi Jbutle60  If the depth image is fluctuating unstably then a way to stabilize it is as follows:

  1.  Go to the Stereo Module > Post-Processing section of the RealSense Viewer's options side-panel.  Use the small arrow next to 'Post-Processing' to expand open the list of post-processing filters.

  2.  Expand open the filter option called Temporal Filter to see its settings.  

  3.  Change the Filter Smooth Alpha option's default value of '0.4' to the lower value of '0.1'.  This should significantly reduce depth fluctuation.  Do not change the Filter Smooth Delta setting.

  The video sticks even with the Stereo Module disabled. With the Stereo module enabled it uses 21% CPU and with it disabled it uses 14% CPU so my machine is not maxed.

  If you are experiencing delay on the RGB stream then please try setting depth at 30 FPS and RGB at 60 FPS.  The RGB sensor on the D435 / D435i models has a 'rolling' type shutter that is slower than the 'global' type shutter on the depth sensor and can result in blurring or lag when the camera is moved quickly.  Increasing RGB FPS to 60 can fix this.

   

  Alternatively, disabling Auto-Exposure and setting the RGB stream's FPS to '6' and using a manual RGB exposure of '78'  can reduce lag.
