    great news :)

    This could end up being the next big thing in PC gaming - we've needed an open, non-proprietary GPGPU physics API for ages, and hopefully this will become a standard for all vendors - be it Consoles, nVidia cards or Via cards.

    Hopefully, free/GPL tools will become available, allowing developers to exploit the API with ease, cheaply.

    So will this let us see alot more independant companies bringing games with innovation?

    People need to stop linking innovation with physics, they aren't intrinsically linked, nor is a dedicated accelerated physics engine REQUIRED to give improved physics in a game or realistic physics or better gameplay.

    Batman was an innovative, and truly great game that really didn't use physics at all to improve gameplay or be innovated, infact the extra "physics" used are pointless and don't effect the gameplay at all, and are really just standard effects used in games for years.

    Nvidia are the only ones pretending improved accuracy in physics is crucial to improved games, its not, games have improved constantly for decades without relying on physics for those improvements. I really can't believe how many people think the only way forwards in games is improved physics.

    Totally agree with you Drunkenmaster.

    Furthermore, if you add in the multiplayer aspect, improved GPU physics will have even less of an impact on gaming until it becomes a basic premise that everyone is assumed to have. Until it can be used to actually alter your gameplay experience, it's nothing more than some eye candy of varying quality.

    It adds nothing to gameplay until it stopped being used as a primary eyecandy booster instead of its real physical properties.

    At least there is a greater chance of this & it will be used when it needs to be & not as a leverage tool by it being used for things just for the sake of it that it really does not need to be used for.

    It improves graphics representation which a few smart cookies might be able to turn it into innovation and new gameplay? :p

    I don't know much about all this though.

    Yeah, agreed.

    I think that hardware-accelerated physics has the potential to open new doors for innovation, but only when a unified non-propriatory standard is available. Until then we will be stuck with only superficial extras, such as were seen in batman or mirror's edge.

    Imagine if soft body or fluid effects could be included into gameplay in the same way as rigid body physics were in HL2... The possibilities are endless. We just need hardware capable of accelerating such things, and a standard on which they can be written.

    I suspect the real thing it can bring is a better sense of immersion in a game.

    It's all to easy to have a sense of immersion shattered when you notice that you're character isn't interacting with the world in a realistic way.

    Accurate physics processing offers one way of improving that level of realism, but it's far from being the only way or possibly even the best way.

    Physics engines have all the capabilities to improve gaming. It just takes the right kindle of game to bring it out. I'm not saying all games can improve wit the addition of a good physics engine I'm just saying it's possible.
    Look at the iPhone as a platform. There are a huge amount of games BASED around physics. Obviously this kind of platform doesn't compete with a real taking pc or even a console but the proof is there in the games. Game companies just have to be imaganitive when creating new titles.

    so all you need for this is an opencl/directcompute capable card?

    That's the idea.

    Remember though, that efficient acceleration through OpenCL isn't yet available. That's what this initiative is trying to achieve - an open source physics package which can be accelerated via OpenCL, rather than through the CPU.

    That's why this open physics initiative is a good idea, if all makers of graphics hardware and all drivers support it then developers can base fundamental gameplay concepts on it.

    Take Little Big Planet for instance, the developers knew that the hardware would support physics so the gameplay is rammed full of physics. PC developers dont have that luxury, nVidia do one thing with Ageia, Intel have Havoc and AMD had whatever method they were thinking of using before this idea.

    We can only hope that the various CPU/GPU makers join forces giving developers confidence enough to start developing games that will take full advantage of physics in their games.

    I totally agree. The reason physics hasn't been a game changer yet is because developers can't yet rely on users having adequate or compatible hardware. An open standard is what is needed to seriously bump-start the use of advanced physics as an integral part of the gaming experience.

    Who's going to support this system? With Havok you pay good money for their support services and they'll help you diagnose all the many different problems you can get with physics in a game. I'd imagine games companies would be reluctant to go with a solution which has inferior support to Havok.

    This is good news. Nvidia have had it coming on the physics front. Not only have they not allowed PhysX to run on any GPU except theirs, but they have been so worried that everyone will upgrade from their GTX2XXs to an ATI HD5XXX, that they disabled PhysX acceleration if the display GPU is not Nvidia, which means that people have no use for their old GTX unless they upgrade to a new 3xxGTX.

    Valve is the only developer i have seen that have used never before tried physics to effect the gameplay.

    Bricks falling down in batman did nothing to batman himself, what is the point in using physics to accurately portray an object that does not effect how you actually play the game.
