When you are playing games, most of the time you want to experience the full performance that is possible with your setup. However, there might be reasons why you would want to limit the frames per second that a game generates. For example, you can lower the power draw or heat output of your computer by limiting the amount of computation. In this post, we will explore how to limit FPS in DirectX 11 games on Windows using Rust.

In the first step, we will explore how we can intercept DirectX 11 games in order to introduce our frame rate limit. After that, we will learn how to inject our code into a game. Lastly, we will implement a way to communicate with the game to set dynamic FPS limits.
