Most but not all samples fail in SwapChain Present() unless I change GetHardwareAdapter() to pass true for third arg - requestHighPerformanceAdapter

HelloWindow works, but HelloTriangle fails.

The adapter Intel(R) HD Graphics 4600 is selected because it comes first when DXGI_GPU_PREFERENCE_UNSPECIFIED and it reports D3D_FEATURE_LEVEL_11_0 but then it crashes in Present():

HRESULT is 0x887a0005 : The GPU device instance has been suspended. Use GetDeviceRemovedReason to determine the appropriate action.

Debug output:
The thread 25936 has exited with code 0 (0x0).

If I change the call to GetHardwareAdapter() to add the requestHighPerformanceAdapter arg then DXGI_GPU_PREFERENCE_HIGH_PERFORMANCE causes NVIDIA Quadro K2100M to be selected which doesn't crash.

Start with GetHardwareAdapter() and the HelloTriangle sample, comparing its adapter selection with HelloWindow. Reproduce the Present() device-removal failure on the Intel adapter and verify whether the sample should handle or avoid that selection; done means the sample no longer crashes under the reported configuration without breaking adapter selection.
