Fraps 

Fraps 2.9 - Fraps (derived from Frames per second) Universal Windows application that can be used with games using DirectX or OpenGL technology.

Main features:

Benchmarking Software - Show how many Frames Per Second (FPS) you are getting in a corner of your screen. Custom benchmarks and measures the frame rate between any two points.

Realtime Video Capture Software - Fraps can capture audio and video up to 2560x1600 with custom frame rates from 10 to 100 frames per second.

All movies are recorded in high quality.

Screen Capture Software - Screen captures are automatically named and timestamped.

The latest Fraps 2.9 release adds support for Vista and DirectX 10 games. With games starting to appear using DirectX 10 graphics, benchmarking, video capture, and screenshots are now all fully supported for these titles.

Vista also includes a new audio subsystem. Fraps can take advantage of this and directly record a sound stream from the machine without requiring any support. This allows you to capture ingame audio even if you are using a USB headset or other audio device which doesn't support a "Stereo Mix" or "What U Hear" recording input.

Since the Vista Desktop Window Manager (DWM) runs through DirectX there is a new option to monitor the desktop under Vista. You can now take screenshots and record video from the desktop just like any other game or 3D application.

It is used for screen capturing, recording and benchmarking. Meaning it can record what is on your screen in video, you can take screenshots of what’s on your screen, and display your FPS (Frames Per Second). Game players find this useful for recording and screen capturing, as well as the FPS counter.
