NVIDIA APEX PhysX Enhancements

Mafia II is the first PC video game title to include the new NVIDIA APEX PhysX framework, a powerful feature set that only GeForce video cards are built do deliver. While console versions will make use of PhysX, only the PC version supports NVIDIA's APEX PhysX physics modeling engine, which adds the following features: APEX Destruction, APEX Clothing, APEX Vegetation, and APEX Turbulence. PhysX helps make object movement more fluid and lifelike, such as cloth and debris. In this section, Benchmark Reviews details the differences made with- and without APEX PhysX enabled.

We begin with a scene from the Mafia II benchmark test, which has the player pinned down behind a brick column as the enemy shoots at him. Examine the image below, which was taken with a Radeon HD 5850 configured with all settings turned to their highest and APEX PhysX support disabled:

No PhysX = Cloth Blending and Missing Debris

Notice from the image above that when PhysX is disabled there is no broken stone debris on the ground. Cloth from foreground character's trench coat blends into his leg and remains in a static position relative to his body, as does the clothing on other (AI) characters. Now inspect the image below, which uses the GeForce GTX 460 with APEX PhysX enabled:

Realistic Cloth and Debris - High Quality Settings With PhysX

With APEX PhysX enabled, the cloth neatly sways with the contour of a characters body, and doesn't bleed into solid objects such as body parts. Additionally, APEX Clothing features improve realism by adding gravity and wind effects onto clothing, allowing for characters to look like they would in similar real-world environments.

Burning Destruction Smoke and Vapor Realism

Flames aren't exactly new to video games, but smoke plumes and heat vapor that mimic realistic movement have never looked as real as they do with APEX Turbulence. Fire and explosions added into a destructible environment is a potent combination for virtual-world mayhem, showcasing the new PhysX APEX Destruction feature.

Exploding Glass Shards and Bursting Flames

NVIDIA PhysX has changed video game explosions into something worthy of cinema-level special effects. Bursting windows explode into several unique shards of glass, and destroyed crates bust into splintered kindling. Smoke swirls and moves as if there's an actual air current, and flames move out towards open space all on their own. Surprisingly, there is very little impact on FPS performance with APEX PhysX enabled on GeForce video cards, and very little penalty for changing from medium (normal) to high settings.

I've set my heart on the recently announced Zotac FTX 480 AMP. This takes the cake! Faster yet quieter, and looks just awesome.

Point my heart, I would like a Fermi limited to 480 SP, but having the full 512-SP.
Not only!, I wish to put in dual-GPU as my current GTX 295 and directly to the liquid cooled heat sink with copper entirely!

Is it just me? or is the 5870 losing less fps when resolution is turned higer compared to the GTX480 or?
