I am trying to figure out what caused Battlefield 3 to slow down on my sons new Lenovo Y500 with dual GT 750M video cards.
When he installed the game about a week ago he was getting around 50-60 fps on high settings and now only about 12 on low.
I cant find anything wrong:
no viruses
No spyware
not overheating
vid drivers up to date
sli on
did battlefield repair (nothing found)
renstalled battlefield
other games run normal
reset defaults on battlefield
power settings on high performance
tried setting nvidia settings to suggested for battlefield and nothing we change in settings seems to make it better

i7 3630qm, 16 gb ram, dual 750M video

Yes I have the latest nvidea drivers for the card(s)
Regarding: Go back to 314.22 or try the lenovo driver
I can try that but don't understand why (if thats the problem) that it was fine last week and got slow all of a sudden
