My Laptop is a Lenovo Z580
i7 3612QM @2.1GHz (up to 3.1 with Turbo Mode)
nVidia GT 630M 2GB RAM
Screen Resolution: 1366x768-15.6"
The resolution isn't the problem, as the GPU is more than capable of handling it. In RE4 I have no fps losses when going from 2x internal resolution to 3x internal resolution and even at 4x IR RE4 is still playable at 20-25 fps (poorly playable) Furthermore my screen resolution is 1366x768 anyway so I only need 2x. I force Anti Aliasing through the GPU, and jaggies are minimal.
As for RAM, Dolphin seems to never really use more than 2 GB so it's fine there.
Resident Evil 4
Running at 28-35 fps
running at 50-60fps
Project Zero 2
running at 24-32fps
I also tested SMG2 and it works at 50-60fps. Such a nice looking game.
