Taksi
Taksi is a straightforward program that works great in capturing live video from different types of 3D games or any 3D application. It helps users compress file formats in real time and contains customizable keyboard shortcuts to help capturing much easier.
Taksi is inspired from Fraps, which also works to capture 3D images from the computer screen. But the best thing about this program is that it is absolutely free; letting you enjoy it anytime.
