     As Godot 4 is still in development, many post process effects have not yet been updated to support stereoscopic rendering. Using these will have adverse effects.
 
 .. note::
-    Godot 4 has 3 renderer options, Compatibility, Mobile, and Forward+. In the future XR desktop projects should use Forward+, and projects for stand-alone headsets
-    should use Mobile. However Compatibility is the recommended renderer for now due to it having the best XR performance.
