Message : SystemInfo: Find primary with EnumDisplayDevices Without DXGI, EnumDisplayDevices is the only way to get the primary device. Previously the code would work on most configs with a combination of AMD, Intel and NVIDIA GPUs but would fail on more esoteric system. Like our try bots that have Matrox GPUs.
