So I have an ASUS X456UQ Notebook running on Windows 10 Pro Build 1607...
I used to play Need For Speed Most Wanted 2012 on my AMD A4-6300 Desktop PC but it was so laggy even on 800x600 resolution so when dad bought me a new laptop, I had to try it out there and to my surprise, all graphic settings on high run smoothly but still on 800x600. I tried bumping up the resolution a little and everything started to lag so I lowered some in-game settings yet lag cannot be eliminated. I noticed that the game is just using about less than 700mb of the dedicated 2GB RAM of the GPU. Shouldn't be my fps stay at high values? The game isn't using that much RAM so why does it lag?

Admirable
Which are the current specs of your new laptop?

Games often do not use all the VRAM of a GPU normally, there's almost always some left.
Your case may probably a CPU bottleneck, that means that the CPU isn't strong enough to keep up with the GPU in that game.

To be sure of that, bump up the configurations of the game, if the FPS ( Lag ) is still the exact same, then there's probablyy a CPU bottleneck there

If that's unfortunately the case, you'll probably have to change your Lap's CPU or don't game on it
