I am supporting a legacy product that requires the D3D9 overlay feature. Am using the Radeon R7 240 card, previously hosted on XP, drivers v14.4 and DirectX9 (I think). Recently had to ‘upgrade’ to Windows 7 embedded using the latest drivers and now dxdiag tells me D3D9 overlay not supported. Tried reverting to drivers 14.4 but no joy. Any help gratefully received.
