["Christopher M. Penalver" <christopher.m.penalver@xxxxxxxxx>]

shuhao, as per http://download.lenovo.com/express/ddfm.html an update is available for your BIOS (1.46). If you update to this following https://help.ubuntu.com/community/BiosUpdate , does it change anything? If it doesn't, could you please both specify what happened, and provide the output of the following terminal command:
sudo dmidecode -s bios-version && sudo dmidecode -s bios-release-date

Please note your current BIOS is already in the Bug Description, so
posting this on the old BIOS would not be helpful.

For more on BIOS updates and linux, please see
https://help.ubuntu.com/community/ReportingBugs#Bug_reporting_etiquette
.

Thank you for your understanding.

Title:
  [Lenovo ThinkPad T420] 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
