The Impact Game Engine has yet to be released but PhobosLab has posted a little teaser. Their game, Biolab Disaster, is shown running on an iPhone 3GS with 60 frames a second! How?

The game is running in its own process and is not using the iPhone’s browser at all. Instead, it’s just using the JavaScriptCore Framework to run the game. All the necessary calls to the Canvas API have been reimplemented with OpenGL-ES and the touch input is passed over to JavaScript to be evaluated by the engine.

One thing to note though, JavaScriptCore Framework on iOS is still private, meaning anything distributed using this, like Biolab Disaster, won’t be allowed in the App Store unless the Framework is bundled within the game.

Back in March, Epic Games revealed an Unreal Engine running 30 frames per second on an iPhone, this is twice that. Project Sword and Epic Citadel were also shown running around 30 frames per second at the September 1st Apple Event. Imagine the possibilities.

Thanks to Mike Rundle for the tip.
