I am getting a problem while playing Crysis 3 in both SP and MP, the display driver is crashing and because of this Crysis 3 is also crashing in mid game, following are my specs:

Core i3 3220
GTX 660
4GB Corsair Vengeance
Windows 7 ultimate 64 bit
Latest Nvidia display drivers(314.07)

anyone else experiencing this problem?

Also after I activated Crysis 3 on 22nd Feb, from the very next day when ever i login on origin it says that some else in logged in with my email id on another location, i immediately changed my password but still is show the same message....what should i do?
