Laptop 1.:
Acer TravelMate 5720
Intel(R) Core(TM)2 Duo CPU T7300 @ 2.00GHz (2 CPUs)
2550MB RAM
Integrated video card:
Mobile Intel(R) 965 Express Chipset Family
Display Memory: 384.0 MB
With the lowest setting ( distances on the minimum, shadows off, texture on the minimum) the game hardly runs, I get about 3-4 FPS, the game is unplayable.
Laptop 2.:
Acer TravelMate 5730
Intel(R) Core(TM)2 Duo CPU P8600 @ 2.40GHz (2 CPUs)
3036 MB RAM
Video card:
ATI Mobility Radeon HD 3470
Display Memory: 1024.0 MB
On this laptop the game runs smoothly with the highest setting.
Hope this helps.
