Folks --
I am (finally) buying a new laptop to replace my old Tiger 10.4.11
intel Macbook (served me well). I am ordering a new Macbookpro, and
wanted advice on graphics-related features.
To optimize graphics speed, I'm going only with options that offer
the NVIDIA GeForce GT 650M with 1GB of GDDR5 memory.
Given that, then I have a question about how the resolution of the
built-in laptop display effects raw graphic performance. The
choices in the lid are 1440x900, 1680x1050, or 2880x1800.
And, more pixels take longer to refresh, right?
So please advise on effect of native res on two cases:
1. Running "scaled resolution" at, say, 1280x800. But, since *all*
the pixels of the native full res still have to be calculated and
painted, I assume 1440x900 is faster?
2. Running with display dark on the laptop and then driving an
external display. I.e. when I use my 23" Cinema, I boot the laptop
such that the lid screen is off/dark/not-in-play. I also do the same
sometimes when driving a projector. In this dark lid case, I assume
*no* calculations are being done for the native resolution in the
lid, and so all three will be equally fast?
tnx,
-f
