It's pretty obvious that nowadays, gamers want more than just pretty graphics in their games. The likes of Crysis, Half Life 2, Call of Duty 4 and BioShock all show that gamers really crave and enjoy realistic physics in their games. To make rendering physics easier, and to compete with Ageia's PhysX, both AMD and NVIDIA planned out physics rendering via the graphics card. Unfortunately for both of their plans, Havok is soon going to release the Havok FX engine. The Havok FX engine is responsible for calculating physics without any GPU support whatsoever, regardless of brands. If Havok FX is adopted across the board, then the prospect of GPU physics is off-limits until at least DirectX11. This is great news for Ageia, which would leave physics to physics processing units, and very bad news for AMD and NVIDIA, who have likely been perfecting their physics engines for the past two years.
