Maybe... The game's requirements state it supports the GeForce 6200-8800.
The 7100 is about as basic a video processor as you can find. And I mean basic
. While it could probably run Warfighter 2, it would likely have to be run at low resolution with low detail levels.
You can buy video cards that kick the living crap out of on-board 7100 chips for as little as $40-60, such as the HD 4650. There are even a few 9600GSO (48 SP models) still available around that price. A few dollars more can get you into a 4670 or 5550. Just about anything would be better than an on-board 7100 chip.
