Um it's pretty good. The files you save are a lot smaller by default than fraps, I think, not sure.
They're both about the same, but I think fraps gives higher quality --> bigger file sizes, and hypercam gives lower quality --> lower file sizes.
Depends how picky you are. I'm just really picky about quality and don't care about file sizes so I use fraps. But whenever I need to record something for longer than 30 seconds then I use hypercam.
