This tool can display the current FPS of your game, the average FPS, how much memory it uses and also information about your PC.
One nice feature that I forgot to mention in the video is the fact that you can “throttle” your FPS. So for example if you want to check if your game will run and how it will run at “10” FPS, you can do that. It’s a good way to debug your physics, etc.
