This is how I fixed my poor FPS in cheese, on Ubuntu 12.04;
1) sudo apt-get install guvcview;
2) Under image controls look for the drop-down menu item "Exposure,
Auto" and select "Manual Mode";
"TAB" select the next option!!!
3) You should "TAB" select to the slider bar beneath "Exposure, Auto"
labeled "Exposure (Absolute) - use your right arrow key to bump up the
selection. Mine was set to "156" so I knocked it up to "157" then down
to "155", and back again to "156". Now my exposure it fine, and I get a
solid 30fps at 1280x720.
I'm not sure how or why this works, but it seems the exposure it set way too
high or something.
Anyway, just quit out of guvcview and launch cheese. Everything should
be working now. Or at least it did for me.

Bug description:
[ Impact ]
This affects the entire distribution, on any laptop with a camera. The
default "camera app" doesn't work well on Ubuntu. Cheese takes up all
most all cpu cycles, and even so the recorded video is choppy. This
reflects poorly on Ubuntu as an OS
[ Test Case ]
* Record video with cheese. t
* Play back in Totem
* Notice how choppy it is
[ Regression Potential ]
Low: The patch just adds another profile to gstreamer that makes it a
higher priority process, and then tells cheese to use that profile.
It's just a configuration change. I have tested and the patches have
the intended result, the video is smoother than before.
The side effect is that, on a fully loaded system, other processes
will not be able to get cpu time as effectively. This should not be a
problem because it's assumed that when you're recording the video, you
won't be using other applications on your machine.
[ Original Report ]
When recording a video with Cheese with a 1280x720 resolution, the
image is blurry whenever there is motion (this might be a webcam
limitation) but after a few seconds there are also massive framedrops.
This results in a jerky video at best, where the audio is at times
completely out of sync with the video.
When scaling back to 640x480 (the next 'best' thing), things are
smoother (at least there are no massive framedrops). But 640x480 is
not widescreen and not even close to HD, making Cheese useless for my
aim of being able to create quick-yet-good-enough-looking headshot
videos for online use.
