Conclusion

Hardware based physics in a game has only been lightly touched by games like Unreal Tournament 3 and games based upon that engine. Mirror's Edge takes full advantage of the PhysX physics engine with a persistent, physical world that interacts with every facet of the game. g While performance with PhysX enabled is less than with it disabled, it is fully playable in every resolution and setting on a single GTX 280. NVIDIA cards with PhysX support provide the best gameplay experience bar none on the game with performance that beat the ATI cards in every respect. With a lesser card like the GeForce 8800GTS 320MB, the GTX 280 showed performance increases of up to 20%. Disabling PhysX showed performance increases in every instance except for Jacknife C. Enabling PhysX allowed for the game to really shine with interactive smoke, glass, debris and wind.
