Free Screen Recording Software?
 

I've tried Camstudio but it really didn't do well, so is there any (free) screen recording software worth purchasing?

Thanks in advance.

I use Bandicam, although the free version will leave an "ugly watermark" that says "bandicam" at top of your videos

How is the video and audio quality?

I use MSI Afterburner, it's free.

Make sure to get the latest beta version. The regular version doesn't have audio recording, I think.

The main function of this program is to configure your graphics card, but it also has a nicely functioning record capability.
