Best screen capturing software for games?

[csukar]

Hi all, just wondering if any of you can recommend good screen capturing software for games, ideally for recording in 1080p at 30 fps, currently i'm using Loilo but just wanted to make sure there isn't anything better.
Also using Loilo one minute of footage produced a file size of 1gb, this seems a little high, or is this normal?

Fraps is one widely used. I don't know it personally but it's supposed to be good.
