Title:
[Lenovo ThinkPad T420] Graphics performance reduced after playing
games for a little bit
Status in Linux:
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
