This is likely due to the extra strain compositing places on a system. However there are also likely inefficiencies somewhere in compiz or in the graphics drivers as low fps is a problem even on powerful systems playing basic 3d games.

One possible solution is to disable compositing when a 3d game is launched, but as of yet I am unaware of a way to do so seamlessly

Thank you for taking the time to report this bug and helping to make Ubuntu better. This particular bug has already been reported and is a duplicate of bug 988079, so it is being marked as such. Please look at the other bug report to see if there is any missing information that you can provide, or to see if there is a workaround for the bug. Additionally, any further discussion regarding the bug should occur in the other report. Feel free to continue to report any other bugs you may find.

...
For even faster graphics performance in fullscreen games, consider trying:
CCSM > Composite > Unredirect Fullscreen Windows
But beware, that is broken on NVIDIA (bug 980663)
