Dedicated Video RAM 64 MB
I'm looking to change my dedicated video RAM from 64 MB to around 1 GB if possible. I recently bought Total War: Rome II and it's running pretty slowly, even on low settings. I used the website http://www.systemrequirementslab.com/CYRI/Requirements to check what the problem was and the only thing it picked up on was Dedicated Video RAM, which says needs a minimum of 512 MB, but is recommended at 1024 MB.
Bearing in mind i don't have much knowledge on computer hardware etc, what would i be able to do about this?. Would I be able to change the settings on my laptop, would i have to install something to change this, would i have to buy a new Graphics Card, or would i have to just buy a new laptop/PC altogether (my HP G56 is 2 or 3 years old)?
