Здравствуйте. Ищу способ отрисовки поверх полноэкранных приложений.
Пробовал GDI. Медленный. Пробовал DirectX:
Direct2DRenderer использует SharpDX.DXGI и SharpDX.Direct2D1. Не отрисовывает поверх полноэкранного приложение.
Возможно есть способ через DirectX как-то напрямую поставлять данные в видеопамять.
Возможно есть способ через инжект своего кода в сторонний процесс.
Есть идеи?
