Huh, contrary to what most people say, my video quality is actually decent, if not good. In the morning to afternoon, my webcam can easily reach the 30 fps mark.
I heard it doesn't function well for Macs, and artificial lights do not work well with the webcam. The best way to get fps for the webcam is from sunlight, turning on electric lights won't affect the fps and overall quality of the webcam much. For this reason, my webcam is not very good at night. If your computer is far away from any sunlight, then I guess that may be a reason why your fps is somewhat low.
And yes, the sound is amazing.
