Your processor is all set to go....
The issue is, with your RAM or VRAM ( whom so ever u want to blame)....
Look, the game already requires 1.5 gb (ideally 2gb) of ram. So, your lappy is just meeting up the expectations or rather lacking a bit (coz all tht 2gb is not free).
And on the other hand when at times your graphics card VRAM requires a bit of help; your system has nothing to give....
I hope u got what I'm saying.... go for a RAM upgrade....
i just saw in the sys requirment post that the minimum req. to play the game is only 1 GB and recommended is 1.5 gb..so why are you saying that 2 gb is less????
