DX11 software mode.

Igor · 2012-07-17T13:11:03

Hi. Is it possible to run DX11 application in software mode on Win7? I've tried but i've had an error "incorrect parameter". I know that i need to put handle of module as one of parameters and i did it but it's not a handle where a window is. Is it ok? Could anyone help me? Maybe anyone has an example? Thanks.

WARP isn't a debugging tool, it's intended to be deployed. So I'm pretty sure you don't need to install the SDK to use it.

Indeed it is part of the D3D runtime - my mistake. Thanks MJP.

Yes. It's not good if it will be nessesary to install DirectX SDK but it's alright.
Ok, here is my code.

D3D_DRIVER_TYPE driver = D3D_DRIVER_TYPE_REFERENCE;

D3D11CreateDevice(pAdapter, driver, 0, 0, 0, 0, D3D11_SDK_VERSION, &pDevice, NULL, NULL );

Also i've tried D3D_DRIVER_TYPE_WARP. And i have HRESULT - 0x80070057(The parameter is incorrect. ) all time.
Yes, i have installed latest DirectX Sdk.

Maybe you need the other 2 [font=courier new,courier,monospace]out[/font] params to not be [font=courier new,courier,monospace]NULL[/font]?

D3D_FEATURE_LEVEL level = 0;

ID3D11DeviceContext* pContext = 0;

D3D_DRIVER_TYPE driver = D3D_DRIVER_TYPE_REFERENCE;

D3D11CreateDevice(pAdapter, driver, 0, 0, 0, 0, D3D11_SDK_VERSION, &pDevice, &level, &pContext );

[Edit] Also, did you see this restriction? It implies that [font=courier new,courier,monospace]pAdapter[/font] should be [font=courier new,courier,monospace]NULL[/font] for a reference driver.

If you set the pAdapter parameter to a non-NULL value, you must also set the DriverType parameter to the D3D_DRIVER_TYPE_UNKNOWN value.[/quote]

Thanks. D3D_DRIVER_TYPE_REFERENCE is working now with NULL adapter.

But i can't create swap chain now.
The function CreateSwapChain returns error - 0x887A0001(DXGI_ERROR_INVALID_CALL).

Also i can't run my application with WARP.

D3D_DRIVER_TYPE driver = D3D_DRIVER_TYPE_WARP;

D3D11CreateDevice(0, driver, 0, 0, 0, 0, D3D10_SDK_VERSION, &pDevice, NULL, NULL );

I have an error "The parameter is incorrect" again.

Any ideas? Firstly i invoke D3D11CreateDevice and secondly IDXGIFactory->CreateSwapChain;

My SwapChainDescription is quite simple.

DXGI_SWAP_CHAIN_DESC sd;

ZeroMemory( &sd, sizeof( sd ) );

sd.BufferCount = 1;

sd.BufferDesc.Width = 640;

sd.BufferDesc.Height = 480;

sd.BufferDesc.Format = DXGI_FORMAT_R8G8B8A8_UNORM;

sd.BufferDesc.RefreshRate.Numerator = 60;

sd.BufferDesc.RefreshRate.Denominator = 1;

sd.BufferUsage = DXGI_USAGE_RENDER_TARGET_OUTPUT;

sd.OutputWindow = g_hWnd;

sd.SampleDesc.Count = 1;

sd.SampleDesc.Quality = 0;

sd.Windowed = TRUE;

I took it from msdn example.

Turns out that it's impossible to create ref device and after that create a swap chain. Only D3D11CreateDeviceAndSwapChain works properly with ref device. It must be bug of DirectX.
