Everyone Check this out! DESTRUCTABLE ENVIROMENTS AND WEATHER!

There’s no reason why physics like that couldn’t be done without the need of a hardware add-on card, I wonder how much Epic is getting in kickbacks from Ageia?

You don't need the hardware card. And a Quad-Core would most likely outperform the current unit anyway.

Why would Epic get kickbacks? There are a number of third-party companies integrating their technology into Unreal Engine 3. They don't pay Epic to do so, they charge licensees to use their integration.

[Dangerdog]

Yeah, you’re right but it should be the other way around. Ageia needs Epic to help try to sell their crippleware product; on one hand the hardware integration for additional physics effects is extremely limited in UT3 but on the other there seems to be a severe lack of physics in the game. If you compare the amount of physics in Crysis to UT3 not only does it show that Ageia hardware isn’t needed it also brings home the fact that Epic unnecessarily has to hold back on things like destructible environments because of the insistence that you can only achieve those effects through the use of the add-in card.

Wrong. They're using the Ageia physics because its cheaper and arguably better than Havok, even without a physx card. All the physics in game are done without a physx card. It's additional stuff created by people that have nothing to do with epic that will require physx. In game, you can merely use your physx card for physics, to take some load off your cpu.

It wouldn't be "fun" online, what would happen if the map was so destroyed you couldn't get around in it?

LMAO!!!!!!!!!!!! that is so true, the whole map destroyed and every 1 would be like.... next map plz

Yeah, because Epic chose not to ruin the game with a ton of destructible environments, physx cards suck. Great logic there. All the physics in game work WITHOUT a physx card-- so the insistence on using one would hardly be reason to hold back the physics.

Crysis just chooses to have a lot of physics, without a physx card. And that's why the CPU requirements are so high, comparitively. Not that I object to this method. PPUS should be an alternative, something to take some work off of the CPU. PPUs are specifically designed and programmed to perform physics, so while they may be weaker than a CPU, they perform physics faster.

With multi-core CPUs becoming more popular and cheaper, PPU hardware will have a difficult time becoming mainstream. It will never be like sound cards or video cards. When you aren't gaming, a PPU is wasting electricity, a multi-core processor will improve computing overall even for single-threaded applications which otherwise have to share CPU time with all of the OS threads on a single core system.
The future for physics will be simulation threads within an application to utilize the cores.

i say that Ageia PhysX card is only a marketing gimmick to make you buy that thing. They could've use Havok as a physics engine too, since Havok is software-only, and it's a great one too!

you see...Bioshock use Unreal Engine 3 and Havok physics, and now UT3 use Unreal Engine 3 and Ageia PhysX (both software and hardware, using software mode if you don't have the frig'n card).

i think Ageia is going nowhere with the physics card, you can just have a dual-core CPU or something. the "free game" available for download (forgot the name of it) that fully use the PhysX card is so goddam slow without the card, it's like a huge gimmick that pushes/forces you to buy the 150$(?) "PPU" Card (PPU for Physics Processing Unit). I'm glad UT3 runs fine on my computer even without that card.

Plus, adding stuff in your computer mean that it disturb your previous airflow, so if you're into silent computing, this PhysX card it not quiet at all and they didn't made the retention holes compatible with 3rd-party heatsink-fans (Zalman, Thermalright, etc...) to make it into a quiet card.

so i wonder why Epic used Ageia PhysX instead of Havok.

netplay-speaking, it would be strange to have both "with" and "without" PhysX cards users on the same server. i mean...if the "with" user see walls debris flies in the sky and some of them hit him...the "without" user won't see that special feature? and will think the "with" user's player died of a sudden heart-attack while in combat? so that mean the debris would be "phantom" meaning it would pass thru any players if you "get hit" by them, meaning you won't get any damage.

Or the other option which Ageia like a lot more: slowing down "without" users and rewarding "with" users.

i might sound really weird there, but it's kinda nonsense, as i said, i'm glad the demo (at least) runs fine on my computer without that crappy physics card. now if i could find a cheap Athlon64 X2 with 1mb L2 cache for Socket 939...

look on ebay, I just bought a 4200+ X2 £55

If you want destructible environments, try John Woo Presents Stranglehold. It uses a heavily modified UE 3.0 with Massive D. You can shoot the walls near enemies and they will stop firing at you to protect their face from debris. At the very beginning of the game, there is a massive fountain which you can shoot the sh*t out of and watch it crumble.
