Fraps can capture screens, benchmark, and more with any game that uses DirectX or OpenGL graphics technology.
Benchmarking Software - Show how many Frames Per Second (FPS) you are getting in a corner of your screen. Perform custom benchmarks and measure the frame rate between any two points. Save the statistics out to disk and use them for your own reviews and applications.
Screen Capture Software - Take a screenshot with the press of a key! There's no need to paste into a paint program every time you want a new shot. Your screen captures are automatically named and timestamped.
Real-time Video Capture Software - Have you ever wanted to record video while playing your favorite game? Come join the Machinima revolution! Throw away the VCR, forget about using a DV cam, game recording has never been this easy! Fraps can capture audio and video up to 2560x1600 with custom frame rates from 10 to 120 frames per second!
