The Realsense SDK 2.0 (librealsense) seems to be much more stable when using it for my SR300 camera. With the old r2 SDK (which silently fails to install automatically due to Facerig's use of the now unsupported web installer), Facerig often crashes when changing webcam resolutions while the realsense module is loaded.

It also supports more and newer models, and does not crash my AMD CPU when hand tracking is attempted, so I would love to see FaceRig support librealsense someday!

A note for anyone getting crashes with realsense on an older Intel or any AMD CPU: Uninstall the hand tracking module from the SDK!
