eTeknix checked out the Nvidia ShadowPlay Gameplay Recording Software
A quote from the article:
We don’t often take a look at software when it comes to graphics cards but Nvidia latest (beta) software is something quite unique. They’ve attempted to integrate functionality that gamers use a lot, that of recording their in-game footage, and make it not only free for their customers to use but also incredibly easy to use and access. Enter Nvidia ShadowPlay which is Nvidia’s (relatively) new beta software that utilises a built in H.264 hardware encoder on the Kepler GPU. ShadowPlay is part of Nvidia’s free GeForce Experience software and it is supported on the GTX 650 desktop graphics card or higher.Nvidia ShadowPlay Gameplay Recording Software Review @ eTeknix
