What does it capture directly to? If it's uncompressed, you don't have the disk bandwidth to record that rate, and most people don't even have the bandwidth to play back such a file. If it's compressed, your CPU likely can't keep up compressing it in real time. i doubt your PC is fast enough to record games. I've never tried it (I don't game), so I can't be certain.
