Hi, I’ve been investigating why nSight doesn’t work for us anymore.
It appears that if I call D3D11CreateDevice and then IDXGIFactory::CreateSwapChain the CreateSwapChain call fails.
However with the same swapchain parameters, if I call D3D11CreateDeviceAndSwapChain, it succeeds !
( We can’t use D3D11CreateDeviceAndSwapChain in our engine, because we might have multiple swap chains for edition tools )
My specs:
GTX Titan
Window 7 64 bit
Visual Studio 2012
nSight 4.5 (64 bit)
Here’s a simple repro, try, with and without the line ‘#define CREATE_DEVICE_AND_SWAP_CHAIN_IN_A_SINGLE_CALL’
#include "stdafx.h"
#include "nsightCrashRepro.h"
