I've just installed 10.9 on a separate partition to test it and saw this! Hope it stays like that in final version!
Wow that's cool, have you confirmed any performance gains?

I confirm - Happened earlier today to me too, running at 1024, but I haven't done any benchmarks - Might be worth comparing graphic benchmarks from this DP1 build to (hopefully soonish) the GM release, I wonder how that will compare :D

Is that just a glitch or did it really give you that much graphics memory? That would nearly triple the currently available amount.

My 2012 air is giving me 512 with 10.8.4, and 1024 with the 10.9 DP1


What's the standard graphics memory for the 2011 air?
Does it change depending on RAM config?

My bad, I forgot that all new Macbook Airs got 512mb in one of the last updates. It used to be 384mb if you had 4GB of RAM.

Does this mean that laptops with 8GB of RAM will get 2G of graphics memory? There must be a point where extra memory can't make up for the slowness of the HD4000.

Would still like to see some benchmarks that prove this isn't just a typo.

I've got the 8GB of RAM ^^ - But not twice the VRAM :(

To be honest, the HD4000 hardly benefits going from 256 to 512.
This is done with a GT330M:

The GT330M is quite a bit faster. Only with the 2560x1600 tests you could see any difference. Gaming on anything higher than 1440x900 is just madness on the intel hd :)
