I have a G56JK with nVidia GTX 850 graphic card. When I bought it, updated all the drivers, I was playing and suddenly FPS dropped from 50 to 12, checked with latest GPU-Z, PerfCap Reason pwr, I googled a lot, a lot! and find out that the problem is new NVIDIA driver for GTX 600+ graphic cards, many of them even the PC ones have this problem, only solution I found is to use older drivers like 334.

I saw a lot of post here about this problem so I decide to post the solution here for everybody.

P.S. : Best place for downloading drivers is Asus support webpage.

G750JM user here, I noticed massive performance drops after updating my graphic driver to the latest, which would be 347.52. Doing a rollback to the previous driver version fixed it for me so I'm gonna say the issue is with the latest graphics driver.

Caastiel, which version Nvidia driver are you running that is working?

Caastiel, thanks, good to know. 347.25 is only 1 release back from 347.52. :)
