This should be confirmed (it is not affected by the kernel version), and
marked as affecting Saucy and Trusty because they both use the Mesa 9.2
series so both Saucy and Trusty get updated to Mesa 9.2.3 as noted
upstream.

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

Status in The Linux Kernel:
  Fix Released
Status in Mesa:
  Unknown
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
