Fantastic screen-capture software that allows gameplay to be recorded in the video format and quality of your choice. But it can also benchmark your on-going game (showing the frame-per-second rate on the corner of the window) and take screenshots of your game - must have for those who want to make videos about their games.
The software come in free and full version. The free version only allows 30s per capture, but the full version (must buy to use) is unlimited. Both versions are malware-free and the site itself is 100% safe.
