Retina MBP vs 2011 MBP - screen rendering

[SixChurchStreet]

In relation to an older non-retina MacBook Pro 15", on a Retina MacBook Pro 15", does Pro Tools render everything smaller (thereby allowing more "stuff " on the screen), or does is render things the same size (but at a higher pixel density)?

A retina screen has a higher pixel destiny, eg same size just sharper looking.

Thank you. I remember in the pre-retina days the "hi-res" option on the MBP rendered things a little smaller giving you a little more screen real estate compared to the standard resolution model.
