Black & White 2
Black & White 2 is basically a mix of city-building simulation with a little bit of strategy and a cute AI creature, which serves as the earthly representative of your godly powers. The graphics engine makes extensive use of practically all manner of effects, many of them pushing graphics cards to their limits. GeForce 5 cards don't support blooming effects, for example, and depth of focus effects are also disabled. The GeForce 7800 GTX in an SLI configuration takes the performance crown in this game.
