NVIDIA Geforce GTX 680 video shows off new features

If you have a PC gaming rig, chances are you want to get the fastest and most powerful dedicated graphics card you can afford to be installed inside it. Today, NVIDIA is announcing its latest and greatest PC graphics chip, the GeForce GTX 680. In a newly leaked video from NVIDIA, the company shows off some of the card's new features.

One of those new additions is being called GPU Boost. Basically, it increases the graphics card's clock speed when it is being used by graphically intensive PC games. The video uses Battlefield 3 as its example and it seems to show that the instant and automatic increase in the card's clock speed results in a big framerate boost in Battlefield 3.

Another new feature is TXAA, which is a new form of anti-aliasing. NVIDIA claims that using TXAA in games will result in far less "jaggies" while playing a PC game without impacting the frame rate.

The GeForce GTX 680 will also allow for games to support more realistic game physics via PhysX. The video shows an example of that where columns are being destroyed in real time without the use of pre-deterimned animation.

Finally, the video shows that game character designers can use the power of the GTX 680 to create more realistic fur on, say, a gorilla-like creature. The video shows this fur support in action, claiming that the demo shows 100,000 individual fur hairs on the creature.

The GeForce GTX 680 can also support up to four total screens running on one card. In addition, up to three of those cards can be used for playing games via 3D Vision support.
