Ageia Physx processor("is this another must have hardware for gamers?")

$250 for just a minimal eyecandy seems impractical

I believe this card wasn't designed to improve performance. This card was designed to improve gaming experience. If you're a gamer who is more into the game immersion experience then i believe this card is for you. If anyone's intention was to improve performance then using this card doesn't do that. You still need a good cpu and gpu to do that.

Correct, This card gives you a ton more of eye candy and particless flying in for the cost of ZERO frames lost, thats the main concept of this card. It was even dubbed as a graphics decelerator when enabled it GRAW and as it actually dropped the min and max frames you could get for just an extra shit flying around the screen.

Oh, did i say that its a videocard? please quote me on that specific lines.

No, you didn't. That wasn't for you. That was for the readers. And I pointed out that subtle absence of a video socket. hehehe... sorry for the confusion, master.

AI ? nope ONLY in-game graphics physics, not ragdoll physics or world physics of the game just graphics physics which can be done by videcards alone.Take this scene for example imagine a fantasy character with "Dante" (DMC) like profile and he is standing on a hill with countless of real time renderd vegination each moved by the wind (as you would see in real world ) along with his hair and his cloth material, thats ingame physics thats where the physics card can be used,adding particles is "not" physics for me.

Well, that's what they said in their site. AI DAW! Daw lang pud. For me it was just all concept since none of us has actually seen a rig that uses or demonstrate it in action.

GPU's dont just speed draw infact the GPU does more mathematical computations per frame compared to a CPU.The CPU sends the scene information per frame to the GPU and the GPU does all the work,The only thing the CPU is responsible is scene transformation and the rest of the entire AI and game enigne.

Perhaps, but the way I understood the API the only computation the cards do is the tracking of coordinates of objects as well as pixel-rendering and shading. The real brain melting part of the math here is relating coordinates of a 3D object from each other. Native operators are still passed to the CPU. So MDAS is still being done on the CPU. (For those who may not know this, AMD has the best instruction set with relation to 3D calculations.) Results are returned to the GPU. This is where the GPU with the best data bandwidth outclasses the older ones. So to put it in simple terms: The GPU is constantly asking the CPU "how much is this?" "What's the result of this" billions of times per second.

OT: In 3D programming there's a coordinate system for each polygon in relation to a 3D world. So, say, if you have a robot consisting of multiple joints walking on a flat surface, each polygon (joint in our example) has its own coordinate system. So with a movement of each joint it must contain the exact location of each edge of that polygon. The joint contains coordinates for its shape. Now, with those coordinates, it must also be computed for it's relation to the rest of the robot parts. Like the X1 and Y1 of this joint is located at X and Y from the rest of the body. Not only that, another set of X,Y and now a Z variable must hold values for that joint's edge coordinate in relation to the surface of the 3D world! Libog noh? Don't worry. I didn't get it either. Ang general idea lang ako. Don't ask me to compute it kay wala ko kita ug symbol sa keyboard for Integration. LOL. Anyway, 3D is a harmony of mathematical precision and relationships. It's daunting but even if you think about it maka appreciate ka when you see those 3D games in action.

My knowledge may be a little outdated but the basic formula for 3D calculations are the same no matter what language you use. Maskin imo pa na i-javascript or actionscript it's possible to create a 3D object using this formula. To verify this you can try looking at the source code of the experimental 3D javascript as well as the 3D cube and pyramid in flash. Those same calculations are what you find inside nvidia's GPU instruction set.

Of course, the CPU can do this but the GPU can do it better and that's why they exist.

Now you're getting the idea.

wait for dx10...

[whoopz]

i think the idea is cool.. it says that the card functions in a triangle with 1. the CPU, 2. the video card which concentrates on 3d images and 3. the physx card which they claim will concentrate on the movement and basically everything that involves physics.

basta para nako, ganahan ko maka witness nga gigamit ni nga hardware with another pc unit b4 i make any decisions. if i find the improvement of the performance worth it, and if ang price pud dili ra kaayo mahal, then diha nako mu decide ug palit. heheheh... i want to learn from the mistake of others IF EVER it's a mistake ang pagpalit ani nga hardware. heheh...

hmmm... maybe i should have used "improvement of the game experience" instead of "improvement of the performance". anyway, thanks for the correction.

How is that in relation to the discussion ?

[StyM]

dx10 supports physics processing.. no need for external hardware..

[EarlZ]

Yes,But we are talking about Ageia's Physx card not the ones that come with DX10 that still needs some sort of hardware to function.

EDIT: Can you include a link where it stated that DX10 will have a direct Physics support. coz i cant seem to find it
