I own a HP G6 2301AX laptop.. Which Come with 2GB 7670M gpu and 512mb 7640G so Total 2.5 GB Of gpu.... With AMD A8-4500 Proccessor... It must be easy for a 2.5 gb gpu machine to handle NFS12 but no... It fail to run that game smoothly... It stucks on between.. And I am just Amazed of the fact it cant handle that game..... So i wnted to know is there anything i can do to improve the performance... like any tweaks or update..
my drivers r up to date...

Firstly, VRAM does not stack together so technically you are running 512mb for the 7640G and 2GB for the 7670m, not 2.5GB combined.
Secondly, I doubt this would be a VRAM issue, more so that those cards are quite outdated and do not possess the processing power...

I'd try turning the graphics setting down to a lower resolutions or quality setting and turning off Anti-Aliasing.

Heres a ranking of those graphics cards by today's standards and they are pretty low, check out this for a comparison.

Hope that helps!
