If you ever wanted to know how much frames per seconds your graphic card renders, then you would definitely want to know about FRAPS. It is a universal Windows application that can be used with games using DirectX or OpenGL graphic technology. In its current form, FRAPS shows frames Per Second (FPS) in a corner of your screen and also take a screenshot with the press of a key while playing your favorite games.
How To Show Frames Per Seconds (fps)
In General tab, Select Start Fraps minimized
This will hide the Fraps dialog screen when you launch your game. Fraps can still be accessed through the icon in the system tray. By selecting this option your current frames per seconds will be shown in the corner of the screen, as shown in screenshot below.
How To Measure Average Frame rate Between Two Points
While in the game, press the key you assigned to the Benchmarking Hotkey ( by default F11 ). This will mark the start of where averaging is to take place. A green box is displayed to let you know that logging has begun, and then the counter is removed for maximum accuracy. When you want to end the benchmark, press the Hotkey again. The average framerate will now be displayed in a red box.
How To Take Screenshots With FRAPS
The Screen Capture Hotkey lets you assign a button that will take a screenshot of the game screen. To change the Hotkey, click in the box and type a new key to be assigned this function(by default its F10 Key). Screenshots can be saved in Windows Bitmap(BMP), Network Graphics(PNG), or Targa(TGA) format into the desired location.
Selecting Include frame rate overlay on screenshots will include the Fraps frame rate counter on your screenshots.
