NVIDIA recently released a video showing off the PhysX goodness present in Borderlands 2. A coupon to download this game for free is shipped with GeForce GTX 660 Ti cards from participating retailers.
Check out this preview of Borderlands 2 running on a GeForce GTX graphics card with all settings on max. Loaded with NVIDIA's GPU-accelerated PhysX technology, the video shows you the incredible effects you can witness in Borderlands 2 when gaming on a GeForce GTX system. Creatures, such as the Crystalisk, spew simulated fluids comprised of hundreds of thousands of particles, allowing explosions and physical interactions to manipulate them after the fact, rendering an unprecedented level of detail previously unseen on any platform. Our GPU-accelerated PhysX technology enables the dynamic, realistic movement of flags, banners, and tarps that react and tear realistically when taking weapons fire, and weapons generate particle fluids, sparks and debris that add extra explosive action to your visceral gaming experience. Borderlands 2 is available September 18th, and for a limited each GeForce GTX 660 Ti sold at a participating retailer or e-tailer includes a free Steam copy of the game: http://www.geforce.com/landing-page/free-game-borderlands-2 Enjoy!
