Xonotic 0.5 Released

Which is why you should instead record demos of the games you wish to capture in video, and make the video using the demo file and not record anything during gameplay.
There's realtime video capture in xonotic too, but you won't get a good framerate. With fraps either.

If it's choppy while recording it'll certainly mess up my gameplay performance.

Please read C. Brutail's response That's the right way to do it. You play regularly with demo recording activated. Then you use the builtin recording feature while re-playing demos. See this link for more information.
You'll notice there are plenty of Xonotic videos on youtube and none of them is choppy

Please guys let's stay on topic, create a new thread if necessary.
