Bill gates: i will economize to buy a lamborguini... '2 seconds later' yeas now i can buy ;p

@Hitman47PL

oh yes I see how you know your graphics cards. It does matter about the GPU Clock speed, but also it matters MORE the clock speed of RAM if the clock speed of the RAM is slow the whole system falls apart! RAM are the 2nd fastest memory's in the PC. GPU only determines how rapidly it will manipulate the memory and show the frams, but it can't achieve high frame rates if it can't access the memory quickly, because the memory is either insufficient or too slow.

[Frontlines95]

@DjTeZac

maybe Nvidia did start first with everything about graphics cards, but after ATI started and made their own graphics cards they beat Nvidia in the production of graphics cards, they firstly invented 1gb cards, and so on. It doesn't matter that 4gb cards are not needed right now, it will be needed in the future. ATI made the card first and now Nvidia is just gonna copy/paste it.

"Nvidia uses GDDR5, while ATI still uses GDDR2-GDDR3" - don't speak to me.

I have HD4890 1gv GDDR5 ram, fail

[codeythesilent]

@Frontlines95

Can't forget the fact ATI supported DirectX 11 first :)

[Hitman47PL]

@Frontlines95 You fail, actually. You don't even understand how a graphics card works and what it uses RAM for. You want to pack 4 GB of ram into your GPU? Go for it. It won't do shit all for you. It will actually most likely slow your GPU down, although not noticeably. You fail to realize what actually matters is the amount of calculations your card can do in a second. The RAM is just merely used to store that and access it quickly.

[shiraq07]

they should call this game "Fart Fighter".

[DjTeZac]

@shiraq07 Oh, and nVidia didn't "make" PhysX, they bought it off AGEIA.

[Frontlines95]

Nvidia just does a copy-paste job from ATI.

ATI gets 4gb cards then you will see a few months later, Nvidia has 4 gb cards.

And games work better on Nvidia cards, because Nvidia pays the developers of games to optimize the game engine to work best on their cards, and make ATI cards not use all of its potential -.-'

ATI was always the best, Nvidia just copy's cards, gets cash and thats why they can do videos like these and make programs like PhysX. Just not cool.

Now let the hating begin!

[DjTeZac]

@Frontlines95 nVidia was the first company to create a GPU instead of a graphics card, who copied who? + nVidia was founded way before AMD started building GPUs (ATI)... games don't need 4GBs of VRam lol, 1-2 are more than enough and even if they did, nVidia uses GDDR5+ while ATI still uses GDDR2-GDDR3.

[EvolverGT]

@DjTeZac I have an ATI with GDDR5.... just saying...

[Hitman47PL]

@EvolverGT so? Packing more memory into a GPU doesn't really do shit for it if it can't calculate any data fast enough to utilize it.

[Nvidia9700MGT]

Everything I see it's two idiots who one farts and one other says its smells xD

[jonasjr96]

whats this software?

[EhLolWhatever]

*accross the simulation* - Automatic update starting in 15:00-

[zorandroid]

And kill about 95% of computers..

[DreadLord786]

stop calling his fart smoke!!!

[kaplis117]

this in bttlefield 3 would be so awsome

[Shazzyb0y14]

20 trillion operations, just to simulate sum1 farting and sum1 just knocking it off?

[yagitka]

ATi cards can't do this....

[Skankyandy]

@yagitka which isnt as good as you would think, it means less developers will implement it due to it only catering for one part of the market in PC gaming.its like physX you dont see that in many games because it's not worth the developers time to add something in only a few people will see.

while competition can be good for the consumer, it can also be bad. since nvidia wont release the technology to other card developers i.e AMD. we dont get to see it get used in alot of games :(

[yagitka]

@Skankyandy You have a point there.

not all games have PhysX on it. But for me I like it when there's PhysX it brings games more life.

[Skankyandy]

@yagitka yeh i just wish nvidia would release the technology properly so more games have it.

even though i have an nVidia card.

[jptc123]

i would like to see this demo or the hair demo run in the first level of Crysis on the beach withought the use of supercooling on the hardware, that would be impressive

[Krayz8o8]

hey ive seen that kind of smoke before!!! oh yeah Little Big Planet!!!!

[TacoTown254]

@Krayz8o8 The ps3 uses nvidia's graphics cards

[MrBlooDudette]

@TacoTown254 The PC can use 4 of them

[TacoTown254]

@MrBlooDudette yeah, I have 3 GTX 470's in my system. PC's will always dominate.

[MrBlooDudette]

@TacoTown254 Heh nice :] running two 460 1gb's in mine.

[l1ambmx]

Well I have a laptop and is struggling to run the simplest nvidia demos but if I get a new graphics card would that help it to run smoothly?

[drKlitzman]

That looks like my fart.

[jaw2floor]

@drKlitzman lol

[d3tach3d]

several fermi gpus in that small environment....show something the average consumer can use, not a demo that costs a 10,000 computer to run...damn nvidia

[d3tach3d]

several fermi gpus in that small environment....show something the average consumer can use, not a demo that costs a 10,000 computer to run...damn nvdia

[webclipper]

More GPU tech gibberish, never EVER going to be part of a game...

[1Heretic]

@webclipper i dont think so, i ve seen a very good simulaton of trees check this out youtube.com/watch?v=JjZc9ayGla­M

[webclipper]

@1Heretic really amazing, but part of what game? see, that's the problem! Such amazing visuals would be heavenly if they make it into a game. Otherwise, they are just more tech-demos.

[1Heretic]

@webclipper But as you can see the technology is available and dont forget that computers are evolving really fast, when a game like oblivion was out at 2006 who would believe that crysis could be possible the next year?

[Intercore222]

@webclipper

"No one will need more than 637 kb of memory for a personal computer." - Bill Gates

You can´t know what will be in the future

[darkside59]

@Intercore222 LoL.. and yet he built Microsoft Vista that uses shit load of memories. LoL..

[Naroon201]

Imagine Silent Hill with this type of fog.

[icommand]

my god/// whats going on with gpu?

[DragiBubi]

freakin great work NVIDIA

i heared 22 trillion actions per sacond thats giant :D

ATI go and jump from the mount everest !!! ( without any parachute)

[MDKlingengeist]

@DragiBubi

Graphics cards fanboys are cute...

In the console market its Nintendo VS Sony VS M$ fanboys and in the PC market its NVidia VS ATI/AMD and AMD VS Intel fanboys. ^^

[ZOMGitsDouchebag]

Whoopsie!

'Betrayed by cntrl V ZOMGitsDouchebag Inadvertivly trolls self, briefly hangs head in shame, then leaves for Lexi Bell homepage.'

[ZOMGitsDouchebag]

What are the limits for a single fermi card running such a simulation with a number of different processes? Do arguments bork this shizz? Yes higher performance with a less host machines in grid systems but, Clean multitasking mechanisms for GPU-accelerated grid systems. AKA simultaneous execution of a graphics app and a CUDA sci-app on one GPU without major drop in frame rate. Matrix multiplication processing percentages of the dedicated throughput rendering times please or GTFO.

[wiktorpanaktuningfre]

we had this already YEARS ago with the smoke box .

[PangusM]

very impressive!

[shaurz]

Nice

[Cigaraholic]

@ZOMGitsDouchebag

Show me one game which has an above-average looking fog effect, Mr.Douchebag.

PS: You picked the right name.

[hibbijo]

@Cigaraholic They said it takes SEVERAL fermi cards to be able to render this effect, that doesnt leave much else for the REST of the game, does it? Hence why he said it can't be implemented in games.

[minipcpro]

@ZOMGitsDouchebag i am not getting it why you even spend time for such a comment. why?

[ZOMGitsDouchebag]

@minipcpro my point exactly, this is a useless exercise for nothing more than a wow from those who would have no use for the computation involved.

[LuBuLegend]

@ZOMGitsDouchebag

you don't really know anything, right?

[BronzeProductions]

@minipcpro What is wrong with the comment made by ZOMGitsDouchebag? Am I not seeing something? It's possible i am just novice to use of this type of capability.

[LuBuLegend]

@ZOMGitsDouchebag

they can't make this in games

Did he really say that?

You REALLY don't have any ideas...

[ZOMGitsDouchebag]

@LuBuLegend and you do not have ears, listen to what they say. Of course there is physics fog ala mafia(ripoff)2 and Arkham(lameass)Asylum. but what they are doing here requires a shitload more math than even four cards can process. So go back to selling your mouth in cars.

[LuBuLegend]

@ZOMGitsDouchebag

You know what Nvidia is doing? They're improving graphics, they're making Graphic cards. Put the two senses together.

[ZOMGitsDouchebag]

@LuBuLegend HurrDurr, We already know that if you daisy chain hardware you get huge increase in processing power. What I want to know is how many errors and junk data is produced from the calculations. Why'd that fan stop? Did that part of the scene gen errors. Are there design errors in the spec for the code standard or the chip and what are they using to check for this? Its not sumthin you can eyeball. I question these things, you can just stand there bugeyed mouth open saying wow.

[sovietspyguy]

@ZOMGitsDouchebag There is more out there than games and movies my friend. You are not aware of how complicated a simulation like this is. You can take all the processing power in the world and it will not be enough to render a single tree with total realism. The more realistic you get, the more processing power it takes. Sure you could use this power to make an awesome looking game world, but that is of no use to many of the people who would use such a product.

[Frankstar22]

good job !

[growingup2204]

jaw drop

[wsm34]

that is sweet!!!
