FPS Control is a browser extension developed by Denis Radin that allows users to control and test the frame rate per second (FPS) in their browser. It is a useful tool for developers and quality assurance (QA) professionals who want to investigate performance issues or stress-test their applications with dropped frames.

With FPS Control, users can limit the FPS and emulate FPS drops using the Request Animation Frame method. The extension provides a user-friendly interface where users can select parameters from drop-down menus, and the changes are applied instantly.

This extension is particularly beneficial for testing applications in low frame scenarios or when experiencing dropped frames. By simulating these conditions, developers can ensure that their applications perform well even under less-than-optimal circumstances.

FPS Control is a free browser extension available for the Chrome platform. It falls under the category of browsers and the subcategory of add-ons and tools. It is a valuable tool for developers and QA professionals looking to optimize their application's performance.
