Physics are the future of gaming. They give immersion a whole new meaning and are the key to true cinematic gaming experiences. For along time, nothing in video games has really felt believable. A firefight in a movie, sends up a dazzling array of environmental destruction, instantly drawing the audience. However, in many games, shooting, something merely results in a few sparks. Now, video games can start to even out the game a little more.
"But we don't need a whole new card for something like physics."
When VGA cards first came out, people said the same thing about them. Who needs a specialized piece of hardware for something like graphics when it can just be done on the CPU? Video cards have brought games alot closer to real life with engrossing visuals.
