Re: hp pavilion g7
just because the laptop has on paper 2gb of Video RAM, it might not be better then a laptop that has 1gb of Video RAM.
When i say "on paper" i mean that it's properly shared with the Main RAM, and not it's own VRAM.
A Graphic card can use it's own VRAM but also take some of the systems main RAM.
You need to look at the dedicated Video RAM spec.
It might just be a software issue though.
Have you tried to disable virtual sync?
this might be the issue. some games doesn't utilize Vsync properly.
Also are you sure you are not using the inbuild GPU in the Core i5?
