Gamers might rely on NVIDIA's hardware for its superior graphical processing power and affordable price point, but it's their gaming technologies that have helped deliver the market share. NVIDIA's "The Way It's Meant to be Played" is a trademarked slogan denoting a direct involvement in software development as much as they focus on hardware. When the Ageia PhysX software physics technology was purchased back in early 2008, that commitment sharpened NVIDIA growing double-edge sword. In this article, Benchmark Reviews will demonstrate how far PhysX technology has come using the recently-released Mafia II video game, which introduces NVIDIA APEX PhysX and GeForce 3D-Vision technology enhancements. While adding PhysX support to a video game is nothing new for NVIDIA, allowing APEX PhysX features to be computed by the computer's central processor is new territory. For this NVIDIA APEX PhysX: CPU vs GPU Efficiency demonstration, our tests c! ompare GeForce and Radeon GPU's against the Intel Core i7 CPU.
