I have Steam installed along with CS:GO, HL2, and Payday 2, and this happens in all of the games: when I start a game, the game seems to run fine at over 60 FPS. Then, the game starts to stutter, to the point where there are severe FPS drops (2 FPS).

The Additional Drivers tab shows:

What can be done to fix this?
