GeForce 8600M GS Game Requirement Analysis
GeForce 8600M GS is a middle class level GPU part of the 8000M Series released by NVIDIA, in 2007.
Very demanding games (e.g. Metro 2033, The Witcher 2) are most certainly unplayable and demanding games (e.g. Crysis 2, Skyrim V) might only be playable on the lowest settings. Moderate and less demanding games, like Call of Duty: Black Ops, should be playable smoothly at Medium settings.
