Every time i play Skyrim my fps works at 60 perfectly fine and then if i do not quick save it every 3 minutes my fps gets cut in half and its just unbearable to play. This never happened before i got the new drivers for my graphics card. Even though the drivers are supposed to give it a performance boost. This also happens in every other game also including World at war which is ages old and far cry 3. Any suggestions???

My specs are
AMD Phenom X6 1090T Processor ^ CPU's 3.2 GHz
8Gb RAM
Direcx 11
NVIDIA GeForce GTX 550 Ti
Windows 7 Ultimate
3.10 is the version of drivers i have.
