I have 2 GB graphics card memory and 16 GB of RAM. Why can't my PC still play games in ultra settings or can I get my on-board graphics card to use the full 16 GB?
My Laptop configuration is : Core i7 3rd Gen, 8 GB DDR3 RAM and 2 GB GEForce GT  Graphics Card. Still it seems very slow sometimes (OS-Windows 7). How can I enhance the speed of my computer?
