VRAM usage unkown

Unity Engine
1

Hey there!
Recently i upgraded my rig and noticed that my VRAM usage under the rendering statistics window is showing unkown. I did a bit of research and couldn’t really find anything relevant so…here i am. My main concern is that unity is not using the cards full potential, or for some reason its having problems supporting it.

I’ll also add that i haven’t noticed any default graphical bugs or anything out of the ordinary, but i’m not entirely convinced the performance is at its full potential.

Specs
OSX lion 10.8.3
NVIDIA GeForce GTX 680MX 2048 MB

P.s - How reliable is the FPS counter?

hey man…might have to do with the fact that it’s over 1GB.a friend of mine has a dell laptop with a 2GB nvidia card and Nvidia Optimus.At first her not being able to play GTA4 was attributed to Optimus.But we later found out that it was because GTA4 did not support >1GB.Not sure if this applies to Unity but could be possible I guess.
