Retina - HiDPI vs non HiDPI

[grabes]

So, I really don't understand what is the real difference between the 2 (HiDPI vs non HiDPI). When I run a 3rd party resolution manager, I notice that Apple sets the resolutions to HiDPI. I feel through unbenchmarked support that HiDPI is slower (its obvious in animations when launching launch control). So why would I run HiDPI? Non HiDPI resolutions have more options, and seem faster. All the googling I have done really keeps applying to non-retina monitors.

well you'd run hi-dpi if you don't want everything to look like crap on your retina screen. Maybe it doesn't bother some people, but it does to me - it sort of looks like a badly compressed jpeg up close. Kinda avoids the point of having one, no?

I also can't notice any discernible difference between hi-dpi and non hi-dpi performance at least on my machine.

I recommend using the proper OS X scaling instead of the unsupported DPI. If you don't know how OS X handles Retina on the rMBP, I'd recommend reading Anand's (of Anandtech) clear and precise explanation:
