San Francisco, Calif., Jan. 23, 2007 – Havok announces today the official release of Havok 4.5, the latest update to its modular suite of artist tools and run-time technology. Fully optimized for Sony PLAYSTATION®3, as well as Microsoft Xbox360 and Nintendo Wii, Havok 4.5 dramatically accelerates the development of cross-platform, cutting edge electronic games, meeting the needs of the world’s top developers and producers. Havok 4.5 allows game developers to scale game content to thousands of dynamically-driven game objects and characters, harnessing the full power and speed of next generation architectures.
Game developers using Havok Physics and Havok Animation products to develop for PS3 will be able to harness the full power of all the SPUs, while maintaining the complete flexibility of the Havok SDK. Havok architecture now scales strongly across all SPUs and runs between 5 and 10 times faster than Havok 4.0 for a typical game scene on the PS3.
Saints Row, amongst others, uses Havok.Very good news. Lost Planet was the first x360 game that i remember touted its Havok engine. Dont remember which version.
