Ageia RealityMark™ (physics benchmark)

[xsnv]

“Average frame rate numbers for each run are then computed and displayed in a chart at the end. Oddly, though, this chart displays a "default" hardware-accelerated result of 35.23 FPS if RealityMark is run on a system without a PhysX card installed”
That makes no since at all. Every system I have seen gets less then 3fps on average without a PhysX card installed. How on earth did they get 35.23fps did they disable the cloth? Can you give a link to that quote? How does that quote prove the benchmark is heavily biased? If its due to the cloth being turned off all it proves is the CPU is not good enough for full cloth. Also you didnt compare the PPU with cloth to the CPU without cloth? Could that be because as the PPU is still faster?







“So, £180 to see moving cloth? Me don't think so. If agei is in the future then i'm more than happy to stay in the present.”
Its more then just cloth it’s also liquids and a 30 to 60% performance boost. Look at COH that gets a large performance boost and new effects with a PPU. BOS gets nice chemical and other liquid effects as well as a speed boost.

The quote's from techreport.

After reading the original at techreport my brain just went click and I under stand them now. I don’t know why I couldn’t understand it yesterday, perhaps last nights long sleep helped.

Anyway 35.23 refers to the average speed people get with a PPU. So the default hardware-accelerated result of 35.23 FPS is for none PPU owners to compare to there score. For some reason I was reading 35fps as the score the none hardware people where getting. Bit of mistake really. Sorry about that.

Still back to your point. I don’t see why that is biased. All they are doing is giving people with software a way to compare there score to hardware. If they don’t post the average hardware score wouldn’t the software score be meaningless?

I think you're missing the point of waht we're saying.

No one's saying a dedicated physics card is useless. The performance (relative compared to a non physics set up) doesn't even come close to justifying it's price tag.

How many games actually suppourt the card? Even with GRAW quite a few people prefered the game without the physics card. I really don't see this taking off (well not ageias implementation anyway)

Like I said, it's not a usless product, it should just cost a lot less for what it offeres.

9ish out now, with they say 100 in development although to be honest I expected about 15 to 20 to be out by now.

just thought id throw my 2pence worth in.
I use fluid effects and particle/physics simulations quite a lot with my work, and to anyone thinking that a single CPU core can compete with dedicated hardware is wrong.
A Cpu is built for multiple tasks and not optimised for specifics, dedicated hardware is, exactly that - built to do one or only a small few things incredibly fast. Fluids and Cloth are two of the most computationaly intesive tasks in 3d.

I agree for the moment, dedicated physics hardware is almost pointless without proper game development support. Sadly i think Ageia are going to be like 3dfx, they started the revolution but will be the first to die out.
Nvidia and Atis solutions, which i think are based on the Havok code will succeed, in a few years everyone will have them and well wonder how we managed without.

I think this will be where Nvidia and ATi's multi-GPU tech will come in useful as they'll probably wind up building cards with a dedicated PPU just as many are coming out with dedicated hardware decoding for HD files, etc. It's only a matter of time and unfortunately, Ageia's marketing department (who should all be shot, judging by their efforts) missed a potentially HUGE opportunity.

I ballzed up the physics timing on my demo (physics weren't at a constant rate). Im fixing and optimizing it now. I got it at 55fps min (with shadows).

I haven't tried this benchmark yet (I'm at work), but Cell Factor runs extremely smoothly on my [email protected]/X1900XT system, at 1680x1050 4x AA, with everything maxed out.

Ok, I have to turn cloth effects off, but £180 for some cloth effects? No thanks

And Pottsey, for the love of Christ USE THE QUOTE BUTTON!

With first cloth program I got 100fps on loading the program and 52 with spacebar hold down. FPS where jumping around a lot it was more 97 to 103 and 48 to 55.

Your missing the point of the card. It’s not just cloth effect, its cloth, liquid and a performance boost.

Ok so £180 for cloth, liquid and a performance boost (in 9 games) ! give me a break.

Indeed, given the fact CPU's are getting faster all the time plus quad core and its rumored nvidias G80 will have a part dedicated to physics processing. The PPU doesn’t stand a chance especially if ATI do something simalar.
