TechPowerUp writes the leaked GeForce 331.65 beta drivers reveal a feature called the GeForce Experience ShadowPlay. This new tool lets you record or stream gameplay in high-quality H.264, with much lower performance impact than with tools like FRAPS and MSI Afterburner.
While apps such as FRAPS capture from the DirectX pipeline, and strain various sub-systems by recording videos into near-lossless AVI formats, NVIDIA might be experimenting with an alternative method, besides recording in formats that don't strain the system too much. ShadowPlay is debuting with a new driver labeled GeForce 331.65 beta, which was leaked to the web. Screenshots of the GeForce Experience also reveal an applet by NVIDIA that lets you control LEDs on reference design GTX 770, GTX 780, GTX TITAN, and GTX 690.
