Reason:
In this game, if resolution is changed, IDXGISwapChain::ResizeBuffers(...) won't be invoked.
So, some variables (such as ID3D11On12Device, ID3D11DeviceContext, ID3D11SharedHandle) cann't be released and reinitialized in real time.

I try to hook IDXGISwapChain3::ResizeBuffers1. However, even I success to hook this function, callback is not invoked, too.

In the callback of IDXGISwapChain::Present, I found pointer of IDXGISwapChain has changed. At last, I hook IDXGISwapChain::Release().
When the old IDXGISwapChain is being released, I clear variables and initialize them when new IDXGISwapChain is created.
This method works well, please confirm it!
