A Frostbite 2 engine real-time radiosity trailer from SIGGRAPH 2010 shows off the power of DICE's Frostbite 2.0 engine that will power their upcoming Battlefield 3. Word is: "A presentation by Per Einarsson from DICE and Sam Martin from Geomarics. The presentation focuses on the implementation and use of Enlighten, a middleware toolkit for computing real-time radiosity from Geomarics. It demonstrates how the technology is used by its integration into the Frostbite 2 game engine. It demonstrates how the workflow, content pipelines and run-time systems are greatly increased with the help of Enlighten to achieve real-time radiosity for use in video games." (thanks VG247). There are also some BF3 details on the twitter feed of Alan "Demize99" Kertz, the senior gameplay designer on Battlefield 3 (thanks Big Download), who mentions "Huge Maps. Tanks Defibrillators. Jets. Team play" and "The focus of #BF3 isn't special forces... we'll leave that to MOH" and "Yes, there will be spotting" and "Dolphin Diving is out. Period" and "There will be a knife, there will be dogtags. No details for now" and "I want players to have to chose between CQB and Long Range, there won't be hybrid scopes because it kills that choice" and "Vehicle/Infantry balance is a focus for me, it will be awesome this time" and "No plans for ziplines or grapple hooks no" and "BF3 will be deeper than BF2. That said we've paid a lot of attention to keeping depth while pacing the learning curve."
