It's a 2011 with NVidia 650M, 16GB RAM, i7. Runs at 1440x900 with medium/low settings with frame-drops a bit more often than I would like.
Might need to drop it down to 720.
Your laptop is three to 4 times times the laptop mine wishes it could be lol, and I'm running it at an acceptable level for my expectations of what archaic technology can do.
For your reference:-
Intel Core 2 Duo T9550 2.8 GHz
8 GB RAM
ATI Mobility Radeon 4670 1GB (This card has only got 1.5x the juice of the 360's Xenos)
Windows 7 Pro SP1
My settings are:-
1600x900, Textures at Ultra, Texture Filtering at 8x Anisotropic, AA Off, Shadows Normal, Shadow Resolution Normal, Level of Detail Medium, Post Processing Off, High Precision Off, Tesselation Off, Hair Quality Normal, Reflections Normal, Depth of Field Off, SSAO Off.
I get 30 - 40 FPS with this setup, and for a really old system like mine, I find that acceptable. I was actually amazed my system could run this game, it looks great. This system can't even run Crysis 3 due to the lack of DX 11 hardware.
