32 Bit Display Buffer Performance

Oculus recommends enabling "use32BitDisplayBuffer" in Unity.  My questions are:

 

  • What are the reasons for this recommendation?
  • Are there any performance implications on Quest or, more specifically Quest 2?  Or is it "just free."
  • Does this also enable a higher precision depth buffer (which I really need!)

Thanks!

    For what it's worth, I can say that enabling the 32 bit display buffer had a fairly significant performance impact in our situation.  We are drawing a lot of objects with simple shaders so are probably fill-rate bound.
