Our journey begins with GameOverlayRenderer.dll – a generic library packaged with Steam that, as the name suggests, handles rendering of the in-game overlay. With that out of the way, let’s get started. Consider this as more of a brief introduction to utilitising the Steam overlay for game hacking purposes. It’s possible that some parts will be applicable to other graphics APIs but that’s beyond the scope of this post.
#HIJACK NVIDIA OVERLAY HOW TO#
This post will show you how to find the functions needed, implement the hooks, and of course, we’ll finish off with an example implementation.įirst things first, be aware that the following method specifically targets the Steam in-game overlay and games using DirectX 9. The most common overlay I can think of is Steam – so that’s what we’ll be using today. The method we’ll be using today makes use of behavior exhibited by most recording software, that is, to exclude in-game overlays from the final video.
This is what I’ve been using for a few years now, but the inevitable performance loss and inability to play the game in fullscreen while using this method is a dealbreaker for most. You can then create a rendering device and draw over the game to your liking. For example, someone broadcasting with a “stream-proof” wallhack would be able to see players from behind walls while those watching on a livestream would be none the wiser.Ī common implementation involves the creation of a transparent window that is placed on top of the game window. what are ‘stream-proof’ visuals? Put simply, it refers to rendering that is visible to the end user, but invisible when livestreamed or recorded to a video. Somehow, despite the eternal procrastination that re-writing one of my larger internal projects has become, I’ve finally managed to make some progress and replace my extremely inefficient method for achieving ‘stream-proof’ visuals with something a lot easier to implement. Rendering with the Steam overlay Streaming without suspicion.
