HUD: "D3D Memory allocated" - what it means?

I have 512M Memory on videocard. When I use “D3D Memory allocated” section for HUD it shows using of ~1.2G.
what it means, and where is realy limit for graphical memory used by application?
(Application is 32bit on 64-bit OS)


I think you are using the old version of Nsight or use some old GPU. “D3D Memory allocated” should been removed in latest Nsight. IIRC, the counter doesn’t mean the real physical memory used in your GPU by your app, it’s more like the memory allocated by D3D, and these memory can be page in/out from video memory of your GPU.


Thank you for answer!
I don’t understand what means page in/out. But it doesn’t matter any more )
