The current 2.2 version of Nsight doesn’t seem to work with DX11.1 (it spits out this every time: “Attempted to read or write protected memory. This is often an indication that other memory is corrupt”), which I guess is understandable considering all the other graphics debugging tools broke as well. Is the new Nsight 3 version going to support DX11.1?
I’ll have to look into it, but it might make it into the release after 3.0.
