Greetings.
I have been trying to create a directdraw overlay for an FPS game so that I could draw certain something over it (windowed mode) (I have been using GDI and it flickers... I know its because of synchronization but I dont want to inject any code into the game)
I would appreciate it if you could give me an example usage of directdraw overlay that actually works. There are some examples I have found but they are not for overlaying windows only full screen and they don't really work.
Thank you for your time.
