to play la noire
Are you trolling?
You get advice that you cant really expect to play games with your laptop...
Your reply is that you can play minecraft at 70fps.
So are we to assume that you think... just becasue you can play minecraft... you should be able to play La Noire?
Thats almost like saying that because your car can get you to your local shops... you expect to be able to win a F1 race with it!!!
There is a saying... "you cant get a quart out of a pint pot"... your expectations are VERY unrealistic and faffing around with a bit of extra graphics mem is not going to cut it.
