NSight 3.2: is there any memory limitations for graphical debuging?

I have installed Nsight 3.2 (because my videocard don’t support further versions).
For sample applications it works fine.
But for heavy project there is a problem:
In normal case the project uses 400M - 1.6G Ram, and when I start it from NSight it consumes 200-300M Ram and freezes forever. When I start project from NSight I see hud is working during short time at begining.
So I think there is a limitation.

I have visual studio 2008 sp1, windows 8 x64, NSight 3.2, NVidia 9600 GT

Problem was because of calling reinitialization(*Device::Reset), now all works properly.


Thanks for your feedback.
