MacBook Pro 512MB VRAM

I have the new MBP with 512MB VRAM
In Unity the stats window says 256MB of VRAM.
If I launch VideoHardwareInfo ( you suggest this program for checking the graphics) the total VRAM is 256MB like Unity:
if I lunch this:

pressing C key I can see 512MB of VRAM.
Witch one is correct?

To change video cards on your mac book pro.

Click your apple / system preferences / energy saver

Then look for this area.

Graphics

[1] Better Battery Life 256 card
[2] Higher Performance 512 card

It will ask you to log out when you make this change for it to have any effect.

what is your set to now?

I’m talking about 9600M GT not 9400.

Well, apparently Apple’s own developer examples are sometimes wrong. For next Unity release, I’m adding VRAM amount reading code from CustomCocoaOpenGL sample. We’ll see if that improves things (I don’t have a 512MB card here to test).
