Sorry to re-open but I wanted to include one more detail - either a
recent update fixed this for me, or a recent change I made to my BIOS
settings (changing my fan speed from "normal" to "turbo" in my
motherboard BIOS) has made me unable to reproduce this hang, even after
long periods of scrolling complex maps in Google Maps.  I can definitely
raise the temperature nearly 10C by doing this, but with the fans on
turbo (and this only seems to make it slightly louder) the hang does not
occur.  Hopefully this will help anyone else with these issues - always
try to cool the processor as much as possible!

Title:
  Graphics performance reduced after playing games for a little bit

Status in The Linux Kernel:
  Fix Released
Status in “linux” package in Ubuntu:
  Incomplete

Bug description:
  I recently upgraded to Saucy. I noticed that everytime I play
  something like Counter Strike Source, my graphics performance drops
  down to something like 15fps while normally it is locked at a max FPS
  of 40fps..

  This slowdown happens and also makes my computer generally pretty
  slow. Thermo maximum has not been tripped (I know, and I actually
  underclock while playing these games).

  I'm not sure why this is happening. It only happens on 13.10. I have
  bumblebee installed. I used both cards to play the game and the same
  thing happens
