I think Beepa is the relatively unknown software company, but they had developed the useful tool called Fraps. Fraps is still working on the appearance of the tool and Its latest version is full support for Windows 7 and DirectX 11.
The small program is shareware, but it can be also with a few limitations for free. This will be displayed in videos a watermark lower right, some limitations in the resolution or at the screenshots there are others.
Anyone who wants to unlock all the features you need to pay 37 U.S. dollars. You can download Fraps software via the site: http://www.fraps.com/download.php
