I want to know is how the resolution-scaling works on the new rMBP. Have i got everything correct if i say that the least resource-demanding setting is to use it as it's native resolution with the help of some app that sets the resolution to 2880x1800? With that setting the OS does not need to scale anything and it should be alot easier for the GPU to handle, right? Also, every picture/graphic should look perfect since nothing get's scaled up? I don't really bother having everything very tiny since i'll mostly will be working with editing photos. The display is always at it's native resolution, it's just how the OS scale and handle different GUI-objects etc, right?
