It is impossible to play this (or any other modern game aside from indies) with that graphics card. Even if you have their absolute fastest card Chrome 540 GTX, you are looking at a card at best on par with something like Radeon HD 4350, which is still far from even the minimum required for Divinity 2. This doesn't even begin to take into account its driver quirks etc, which could prevent it from running any newer games.
