How do you obtain the IDXGIAdapter with the best rendering performance in case of multiple adapters?
IDXGIFactory3 *factory = NULL;
CreateDXGIFactory(__uuidof(IDXGIFactory3), (void**)&factory);
IDXGIAdapter1 *a1;
for (UINT i = 0; factory->EnumAdapters1(i, &a1) != DXGI_ERROR_NOT_FOUND; ++i)
{
IDXGIAdapter2 *a2;
a1->QueryInterface(__uuidof(IDXGIAdapter2), (void **)&a2);
DXGI_ADAPTER_DESC2 desc;
a2->GetDesc2(&desc);
wchar_t *d = desc.Description;
}
