NVIDIA’s PhysX in Dark Void
There is no doubt about it, PhysX makes a tremendous visual difference in Dark Void. The advanced particle effects enabled by PhysX make land combat an exciting and richly detailed experience. Between the shards of broken enemies, the dust clouds from bullet strikes, and the awesome torrent of particle streams from the Disintegrator cannon, combat in Dark Void is just plain awesome with NVIDIA’s PhysX technology running the show. Even Will’s jetpack is made more awesome with PhysX. That isn’t to say that the jetpack wasn’t cool without it, but with PhysX running on High, the stream of smoke coming out of the little jet engines is thick and dense and cool.
At the end of the day, what we are talking about here is still nothing more than some eye candy. PhysX is not a game-changer for Dark Void. It makes the game prettier, but it doesn’t actually change the way the game is played. That is, of course, logical. If Airtight had made Dark Void’s gameplay mechanics depend on the presence of PhysX acceleration, there would be a few limitations in place. First, they would potentially cut themselves off from a rather large swath of customer with AMD’s ATI Radeon graphics cards. If they didn’t want to do that, they would be forced to lower the complexity of their PhysX-based content so that it could be effectively calculated on the CPU.
For a game developer to embrace PhysX from top to bottom and commit the entire game to requiring NVIDIA hardware, they would condemn the game to relative commercial failure. So for now at least, PhysX is going to remain almost completely effect oriented. It looks cool. For the foreseeable future, that is all it will do for mainstream games.
