+== Using VirtualGL with the VGL Transport
+[[PageOutline]]
+
+=== !Advantages/Disadvantages of the VGL Transport
+
+==== Advantages
+    * Every application window appears as a '''separate window''' on the user’s desktop.
+    * consumes fewer server resources, since the 2D (X11) rendering occurs on the client machine
+    * supports stereographic and overlay rendering
+
+==== Disadvantages
+
+    * The VGL Transport relies on the chatty remote X11 protocol. \\ As a result, the VGL Transport is '''not recommended''' for use on high-latency or low-bandwidth networks.
+    * As with any remote X11 app, if the network connection drops, then the application '''will exit'''.
+
+
+=== Using VirtualGL with the VGL Transport requires four general steps.
+1. '''Install VirtualGL''' on your local machine.
+2. '''Start an X Server''' on your local machine.
+3. '''Connect to JURECAVIS''' with vglconnect -s.
+4. '''Start the application''' with vglrun.
