NVIDIA PhysX technology helps games play better and feel better by making interaction with environments and characters far more realistic than ever before. By making behavior more realistic, the graphics look and “feel” better.
In the beginnings of 3D Gaming, characters and worlds were basically built from boxes with decals on them. As technology has advanced, the boxes have become more geometrically detailed polygons, and the decals have become more accurately shaded and lit textures. However, most people still perceive an “uncanny divide” between a game environment and reality that prevents a proper suspension of belief and immersion into the world of the game.
Before PhysX, game designers had to “precompute” how an object would behave in reaction to an event. For example, they would draw a sequence of frames showing how a football player falls on the ground after a tackle. The disadvantage of this approach was that the gamer always saw the same “canned” animation. With PhysX, games can now accurately compute the physical behavior of bodies real time! This means that the football player will now bend and twist in all different ways depending on the specific conditions associated with the tackle – thus creating a unique visual experience every time.
PhysX technology is widely adopted by over 150 games and is used by more than 10,000 developers. With hardware-accelerated physics, the world’s leading game designers’ worlds come to life: walls can be realistically torn down, trees bend and break in the wind, and water and smoke flows and interacts with body and force, instead of just getting cut-off by neighboring objects.
How it works:
PhysX is designed specifically for hardware acceleration by powerful processors with hundreds of processing cores. Because of this design choice, NVIDIA GeForce GPUs provide a dramatic increase in physics processing power, and take gaming to a new level delivering rich, immersive physical gaming environments with features such as:
Explosions that create dust and collateral debris
Characters with complex, jointed geometries, for more life-like motion and interaction
Spectacular new weapons with incredible effects
Cloth that drapes and tears naturally
Dense smoke & fog that billow around objects in motion
Includes the latest PhysX runtime builds to support all released PhysX content.
Changes & fixed issues in this release
Fixes a bug that caused the Metro Last Light to not be GPU accelerated on some systems.
Supports NVIDIA PhysX acceleration on all GeForce 8‑series, 9‑series, and 100‑series to 700‑series GPUs with a minimum of 256MB dedicated graphics memory.
Note: Some applications may have higher minimum requirements.
Experience GPU PhysX acceleration in many games and demos, some of which are highlighted in PowerPack downloads here.
Supports NVIDIA PhysX acceleration on GeForce for SDK versions 2.7.1, 2.7.3, 2.7.4, 2.7.5, 2.7.6, 2.8.0, 2.8.1, 2.8.3 and 2.8.4 (requires graphics driver R310 or later).
Note: For games that use SDK versions before 2.7.1 the PhysX Legacy Installer must also be installed. These are games that were released around the end of 2007 or earlier. (AGEIA titles) Examples of these games include CellFactor, Clive baker’s Jerich, Gears of War, Pirates of the Burning Sea, Switchball and Velvet Assassin. The PhysX Legacy Installer is available here.
Supports control of your GPU PhysX configuration from the NVIDIA display driver control panel.
AGEIA PhysX processors users should use and install older PhysX system software such as version 8.09.04. Note – AGEIA PPU acceleration support for 2.8.1 SDK or earlier, and Windows Vista and Windows XP only.
Supports NVIDIA PhysX acceleration on all GeForce 8-series, 9-series, 100-series, 200-series, 300-series, 400-series, 500-series, and 600-series GPUs with a minimum of 256MB dedicated graphics memory.
