Fraps
Fraps - a program designed to count the number of FPS (frames per second) in applications running in OpenGL and Direct3D modes. The utility can take screenshots and record video with images from the screen. This is a universal application capable of working with all games that use DirectX or OpenGL technologies. You can control the program without leaving the game, using hotkeys. The main thing is to make sure in advance that Fraps hotkeys do not coincide with the keys used in the game. With Fraps you can capture the best moments not only as individual frames, but also in motion with sound. It allows you to display statistics of the frames-per-second parameter values by writing it to a file, or display the counter in one of the corners of the screen. Saves individual frames when you press a hotkey.
