Michael Brown of Maximum PC has an interesting write up of GRAW 2. Apparently Michael has been a fairly vocal critic of Ageia but the implementation seems to have turned his head. Here is a snip or two:
"Ageia tells me all the physics in the game were created using its PhysX SDK, but only one level (dubbed Ageia Island, appropriately enough) requires a PhysX card—you can't unlock the level without it. Could this be just a marketing ploy? I guess it's possible, but I’ve never seen such detailed physics in a game."
"The guard tower is even more remarkable. You can act with stealth and take out the enemy soldier with a sniper rifle, or you can launch an RPG, blow the entire structure apart, and watch him tumble down to his death. The first time you try this, you’ll undoubtedly get blown away yourself because you’re too busy watching the destruction unfold before you."
Looks like (as I mentioned in my previous post about GRAW2) this might be the real deal as far as engaging gameplay influenced by physics.
In the upcoming Ghost Recon Advanced Warfighter 2 title from Ubisoft will be a little nugget for those of us with an Ageia card - a special 'Ageia Island' level. According to Ageia it will have fully destructible environments. The level of Physx interaction in this title seems to finally reach that physics nirvana - where the physics effects can influence gameplay. One example they use is knocking boards out of a fence to take pot shots at your enemy. One of the biggest benefits in my opinion to this integration is that the game will play differently every time depending on your approach. You could make a clearing if you wanted to, or even knock down trees for a great 'cutline' sniper shot. Find the press release here.
Over at the Inq Wily Ferret has a great write up about the Unreal 3 engine and the native Physx support. In a nutshell Tim Sweeney indicates that if you are running a quad core system then the physics threads can be pushed onto the third and fourth cores. Considering the adoption rate of quad core processors (basically nil) and the premium in going from dual to quad, at this time if physics are what you are looking for on Unreal 3 based games, head on over a grab a Physx card.
