| The resulting d3d10sw.dll implements D3D10's software rendering interface, like |
| WARP. |
| |
| |
| It can be used directly from WLK 1.6 and WHCK 2.0 D3D10+ tests, via the -Src |
| and -SWDLL options. For example: |
| |
| wgf11blend.exe -Debug -DoNotCatchExceptions -DXGI:1.1 -FeatureLevel:10.0 -Src:SW -SWDLL:d3d10sw.dll -LogClean -LogVerbose |
| |
| However, as of WHCK version 2.1 this mechanism no longer works reliably. |
| Either you use WHCK 2.0 binaries, or you must use the alternative method |
| cribed below (of copying d3d10sw.dll into the executable directory and rename |
| it such that it matches the D3D10 UMD of the test machine). |
| |
| |
| Examples can be easily modified to load it too: |
| |
| D3D10CreateDeviceAndSwapChain(NULL, |
| D3D10_DRIVER_TYPE_SOFTWARE, |
| LoadLibraryA("d3d10sw"), /* Software */ |
| Flags, |
| D3D10_SDK_VERSION, |
| &SwapChainDesc, |
| &g_pSwapChain, |
| &g_pDevice); |
| |
| D3D11CreateDeviceAndSwapChain(NULL, /* pAdapter */ |
| D3D_DRIVER_TYPE_SOFTWARE, |
| LoadLibraryA("d3d10sw"), /* Software */ |
| Flags, |
| FeatureLevels, |
| sizeof FeatureLevels / sizeof FeatureLevels[0], |
| D3D11_SDK_VERSION, |
| &SwapChainDesc, |
| &g_pSwapChain, |
| &g_pDevice, |
| NULL, /* pFeatureLevel */ |
| &g_pDeviceContext); /* ppImmediateContext */ |
| |
| |
| Alternatively, it can be renamed into the system's D3D10 UMD driver (e.g., |
| vm3dum_10.dll for VMware vGPU, nvwgf2um.dll for NVIDIA GPU), and placed into |
| the application directory, or system's directory, and used instead. |
| |
| For the DLL to be picked from the application directory you'll need to do the |
| following once: |
| |
| reg add "HKLM\System\CurrentControlSet\Control\Session Manager" /v "SafeDllSearchMode" /t REG_DWORD /d 0 /f |
