Cryostasis Tech Demo! PhysX ağırlığını gösteriyor! (indirin)
http://www.nvidia.com/content/graphicsplus/us/download.asp

Evet arkadaşlar bu siteden indirebilirsiniz.

Ben hayatımda bu kadar etkileyici fizik efektleri görmedim. Oyunun grafikleride harika.

Ati kart sahibi arkadaşlarda indirebilir. Zira PhysX hardware da software da açılabiliyor.

Yani bu muhteşem efektleri Ati kart sahipleride görebilir(ağır çekimde olsa).


Ben 8800gt ile 1680X1050 ayarlarda ortalama 24 FPS gördüm (DX10) , PhysX işini Software yaptığımda 6-7 FPS gibi değerlere düştü.


PhysX tek kelimeyle muhteşem bir teknoloji arkadaşlar, herkese indirmesini tavsiye ederim. Bu arada oyunda mükemmel geliyor gibi.

Not:Test Vista uyumludur.

Physics Drivers Outrage: Nvidia Guilty?

Opinion - When we published an article detailing Nvidia’s advantage in 3DMark Vantage, we had a good feeling that data might spark some controversy. Using GPU for physics calculation in a CPU benchmark highly suspicious thing in any way you look at it. And in fact, it all appeared that Nvidia has been caught with its hands in a cookie jar. Finger-pointing was the result, but as it turns out, there are always two sides to the story and the benchmark maker has an entirely different opinion.

It isn’t like Nvidia and ATI have always played nice. And if you notice anything but the usual in this industry, you would suspect cheating, just like it is the case in this recent physics outrage, which came up since Nvidia is claiming a huge advantage in the 3D Mark Vantage physics test. Earlier this year Nvidia was involved in the highly controversial Creedgate, when Ubisofthttp://en.wikipedia.org/wiki/Ubisoft found that its "The Way It’s Meant To Be Played" Assassin’s Creed title was faster on ATI cards. The company decided to remove DX10.1 support, since the game was not just slower, but also unstable on GeForce cards. The explanation following this controversy was received as being rather doubtful.

In the most recent case of accusations, AMD claims that Nvidia has been fiddling with the 3DMark Vantage benchmark. Just several hours after that story was published, ATI partners contacted us with similar claims about Unreal Tournament 3. The whole revolves around Nvidia’s driver version 177.39.

It all would be fine and dandy if somebody actually had called representatives of the two software companies and asked them for an explanation about what actually happened. We were able to contact those companies and received surprising statements from Oliver Baltuch, president of Futuremark and Mark Rein, vice president at Epic Games.

Let’s take a step first and look how the physics case unfolded:

November 2004: Nvidia introduces its first commercial chipset supporting multi-GPUs - the nForce 4 SLI for AMD platform. AMD downplays the value of multi-GPU cards, claiming that the value lies within a single-die GPU.

February 2005: Nvidia announces that the company has shipped three million SLI-capable chipsets.

March 2005: ATI’s unveils the never-actually-launched X850 Crossfire platform, consisting of two Radeon X850 boards connected via an external cable. The solution never saw any real volumes.

March 2006: GPU Physics begins its life as a marketing gimmick between ATI and Nvidia. Both companies announce GPU Physics at GDC Spring in San Francisco using Havokhttp://en.wikipedia.org/wiki/Havoc FX, a sub-set of the Havok physics API that used the GPU to "animate" physics. Was never really true Physics.

May 2006: At E3 2006 in Los Angeles, key game developers criticized Havok FX and decided to go either with Havok or Ageiahttp://en.wikipedia.org/wiki/Ageia ’s PhysXhttp://en.wikipedia.org/wiki/PhysX API - since both APIs are CPU agnostic and work on almost all platforms.

June 2006: ATI was the first company to demonstrate the new technology at Computex in Taipei. ATI used a system with three X1900XTX graphics cards.

September 2007: Intel buys Havok and Nvidia/AMD open negotiations with Ageia. AMD did not want to pay for Ageia and decided that the role of physics on a GPU should be buried.

November 2007: At the AMD Phenom launch in Warsaw, AMD’s developer relations manager says: "GPU physics is dead for now".

February 2008: Nvidia announces the acquisition of Ageia.

April 2008: During its Financial Analyst Day, Nvidia announces that a physics driver will be available to the general public by mid-summer. The first public demonstration did not go as planned, but the potential was clear.

June 2008: Nvidia releases PhysX Application Software 8.06.12 first to the general press, then to the public. This version of PhysX enables GPU acceleration of the PhysX API. Controversy sparks around 3DMark Vantage and Unreal Tournament 3.

Looking back in history, we notice that ATI’s first reaction to multi-GPU was negative, but the company followed suit with Crossfire and now the company is preaching about advantages of smaller GPUs instead of large monolithic dies. Later, AMD was downplaying the value of GPU physics and then announced that it found an agreement with Intel/Havok. But this move was "too little, too late" for companies like Epic and Futuremark, who made their design calls years ago. AMD didn’t work on GPU Physics and even tried to bury it. As a result, PhysX has become the physics API of choice for more than 150 games and Futuremark used PhysX in its benchmark.

AMD’s Official Statement: Nvidia fools 3DMark Vantage

The issue with AMD attacking Nvidia over 3DMark was summed in an interesting article by my ex-colleague Charlie Demerjian. We have received an official statement from Dave Baumann, former head of Beyond3D and now in a senior technical role inside AMD’s graphics unit:

"We believe physics simulation, whether performed on the CPU or the GPU, will be an increasingly important feature of upcoming games. The powerful parallel processing capabilities of modern GPUs have been proven to be very useful for accelerating some types of physics calculations, such as cloth simulations and rigid body collisions, used to enhance game visuals. However, using the GPU in this way only makes sense if it doesn’t detract from graphics rendering performance. In other words, adding a few more moving objects into a scene isn’t necessarily beneficial if it requires other 3D effects to be simplified, or sacrifices resolution and frame rate.

3DMark Vantage attempts to address the growing importance of game physics by including support for GPU-accelerated physics in the GPU tests, implemented using DirectX 10 geometry shaders. The developers balanced the physics and rendering workloads in a way they felt was reflective of what we would see in next-generation games. Additionally, they included CPU tests that supported the use of Ageia PhysX PPUs to offload some physics calculations from the CPU. This decision was made prior to the acquisition of Ageia by Nvidia, and the subsequent discontinuation of discrete PPU products.

Recently released drivers from Nvidia (ForceWare 177.39) fool the 3DMark Vantage benchmarks into thinking an Ageia PhysX PPU is installed, while actually doing the additional physics processing on the GPU. Since Vantage has separate GPU & CPU benchmarks which both include physics processing, this causes the performance benefits of GPU physics to be double-counted, resulting in an artificial inflation of the final score. Real games can be expected to limit the amount of GPU physics processing to avoid significantly impacting rendering performance. Also, we are confident that the vast majority of upcoming game titles will not include support for PhysX, but will instead rely on more popular physics middleware (such as Havok) or proprietary physics engines, which will not benefit in any way from Nvidia ’s PhysX drivers."

Summing up, AMD claims that the ForceWare 177.39 driver "fools" the 3DMark Vantage benchmark. We’re not so sure. Ageia has built a very solid library of titles that use the PhysX API. Being a standard library within the Unreal Engine got Ageia more than one hundred contracts alone. PhysX is the most common used physics API for console games (NovodeX and Meqon APIs) today, Sony has licensed PhysX SDK as the official physics engine for Playstation 3 console, Microsoft licensed PhysX for their own Robotics Studio and the list goes on. So, why would we undermine PhysX’ value as an API? Because of Intel’s Havok?

Wasn’t this a case of "fooling" a benchmark in the first place?

Futuremark: No cheating here

3DMark Vantage is in the hot seat as far as Nvidia’s PhysX goes, because this is the first time that a GPU is influencing CPU scores. AMD claims that Nvidia violates BDP Driver Rules. This is what Futuremark’s had to say:

"The driver in question has not been submitted for authorization and is only for demo purposes only. Nvidia has followed the correct rules for driver authorization and the BDP by sending us the 177.35 published driver (the same as AMD has now sent us the 8.6 published driver), both of which are currently undergoing the Authorization process in our Quality Assurance area at this moment.

Only drivers that have passed WHQL and our driver Authorization Process have comparable results that will be allowed for use in our ORB database and hall of fame. Other drivers which have not been submitted will not be commented on. Otherwise, we would have to inspect every Beta and press driver that is released.

Our application is not changed in any way, thus any statement implying otherwise is incorrect."

According to Futuremark, Nvidia did not violate BDP Driver Rules. Then again, they didn’t state that the 177.39 drivers were legit either. However, the 177.39 driver will not enable Physics on a GPU, it is the PhysX 8.06.12 Application Software. We spoke with Oliver and other members of the Futuremark team and learned that they have no issues with the PhysX Software 8.06.12 because it is WHQL, but the display driver has to be certified as well. Once that is done, both PhysX 8.06.12 and 177.35 will be certified for use on ORB.

The only difference between future WHQL driver 177.35 and 177.39 is the inclusion of GeForce 9800GTX+, a strangely named 55 nm die-shrink of the G92 chip.

Epic Games: It’s customer service

Following conversation with Futuremark, we spoke with Mark Rein, VP of Epic Games. Mark is known to be quite knowledgeable when it comes to new technologies and the company isn’t shy about pointing fingers even at the largest corporations.

When it comes to the topic of physics on a GPU, Mark believes that using GPU for physics is not a cheat. Rather, he considers this feature a bonus for users of Unreal Tournament 3 who own Nvidia graphics cards.

Those users can now play games that offer features that were designed for an Ageia PPU simply by using their high-end GPU. The only thing that Nvidia did was to change the library that we shipped with the game, and ultimately made those levels run better."

Mark called it ironic that nobody cried foul when Epic released the UT3 Bonus Pack, which contained PhysX-enabled levels and required an Ageia PPU to run. Nvidia’s purchase of Ageia made this technology available to millions of gamers, instead of several thousands (according to some sources, Ageia shipped only 120,000 boards).

Mark chose to call Nvidia’s PhysX driver "customer support". He mentioned that Nvidia had a long history of going the extra mile to improve their customers’ PC gaming experience through driver features and optimizations created by working closely with developers.

Personally, I have been propagating physics in games for ages now, because it is the only way to enable the creation of realistic games. For me, physics can be Havok, PhysX or even Ray tracing, but games and other applications should have physics, because looks are nothing, if the game creators cannot put their feelings about the world into motion.

How many times did we complain about race cars not crashing when they are touching a curb or passing the grass at very high speeds? Physics is the answer, and Nvidia’s PhysX is one of the roads that game developers can take.


Nvidia: PhysX driver for public arrived, PhysX part is WHQL certified

At the end of the day, we asked Nvidia when the PhysX driver will be available to general public. More importantly, when there will be a WHQL certified driver so that Futuremark can approve it. We were given an answer by Bryan Del Rizzo, one of the members of Nvidia’s PR team:

"The PhysX system software is WHQL. [The] 177.39 display driver is BETA (so the co-installer will be under beta downloads)"

This answer didn’t exactly satisfy us, we wanted to hear when will the driver be WHQL’ed and when will the driver go through Futuremark’s BDP Driver Certification process.

Nvidia sources told us that that the WHQL display driver is currently being certified at Microsoft. The release is expected by mid-summer. While a specific date was not given, commons sense suggests that WHQL driver will be available when 9800 GTX+ cards ship - which will be July 11.

For now, you can find official beta driver on following pages: 32-bit Windows XP, 32-bit Windows Vista and 64-bit Windows Vista .
If you want the PhysX Application Software in stand-alone form, download link is here. So far, supported boards include GeForce 8, 9 and the GTX 200 series.


Conclusion

To us, there is a clear conclusion of this matter. AMD rained on its own parade and the launch of its excellent 4850 and 4870 cards. We got the impression that the software vendors in question believe that their products benefit from GPU physics and that accelerating in-game physics with a GPU was a positive move. Forget corporate politics for one minute and figure this one out: Nvidia modified PhysX and brings it to millions of owners of GeForce cards. We would say around 10 million, since we do not think that 8600 versions and below are capable of serving PhysX demands with graphics.

If you own a GeForce 8800, 9600/9800 or GTX 200 series, we can only recommend a download of the latest drivers and PhysX software when they become available and start playing those levels in Unreal Tournament 3, Ghost Recon and other PhysX games.

GTA4 PS3 sorunları. 630P çözünürlük rezaleti.
Evet arkadaşlar ben PS3 kullanmıyorum. Ama özellikle Xbox360 tan 1 sene geç çıkması ve o dönemde yapılan vaadler ile hepimiz PS3 ün Xbox360'ı rezil edeceğini düşündük.


Çıktı Xbox360'ın yanına yaklaşamadı Programlanması zor dediler yoksa daha iyi PS3.


Ama şu an internette dolanan çok sert yazılar var. Rockstar'ında kabul ettiği üzere büyük sorunlar yaşanıyor hatta kendileri Autosave özelliğini kapatmayıda içindew bulunduran 13 tane öneride bulunmuş bu sorunlar görünmesin diye. Linki;

http://www.techpowerup.com/59334/Take-Two_Suggests_PlayStation_3_(PS3)_GTA_IV_Fix.html


Bütün bunun üstüne daha da rezil olan. Sony nin iddiası vardı çıkmadan, oyunların çoğu 1080P olacak diye.

Ama rezalet GTA4 ün Xbox360 versiyonu 720P olmasına rağmen, PS3 versiyonu yanlışca 630P imiş.

Yani 1280X720 yerine 1120X630 çözünürlükte oynuyorsunuz. COD4 te de bu durum olmuştu. Yakında PS3, PS2 çözünürlüklerine dönüyor gibi. HD Gaming sloganı nerede. 630P linki;

Ben şahsen artık PS3'ün herhangi bir durumda Xbox360'ı geçeceğini düşünmüyorum.

Assassin's Creed'in DX10.1 desteği kaldırılıyor.
Duyuruya göre Ubisoft Assassin’s Creed'in PC sürümü için yama çıkarma hazırlığında. Bildirilen sorunların çoğu DX10.1'i işaret ettiğinden gelecek yamayla DX10.1 desteği kaldırılıyor. Ubisoft yeniden uygulamaya geçmeden önce üstünde çalışılacağını belirtiyor. Oyuncuların DX10.1 destekleyen ekran kartlarıyla gördüğü performans artışı ise geliştiricilerin bazı render işlemlerini ortadan kaldıran uygulaması nedeniyleymiş.

Ne yama ne de DX10.1 desteği için kesin bir tarih verilmemiş.

http://forums.ubi.com/eve/forums/a/tpc/f/5251069024/m/6571038256 duyuru burada arkadaşlar. Forumda Ubisoft resmi yetkilisi belirtmiş.


Bu arada Dx10.1 de performans artışının nedeni Post Fx renderingin kapanması imiş.

Nvidia PsysX desteğini herkese açıyor. Atide ileride destekleyebilir.
Nvidia confirms its commitment to making PhysX an open standard for everyone


After Nvidia’s CEO, Jen-Hsun Huang, said that Nvidia planned to provide PhysX support in CUDA, many people (including us) thought this meant that Nvidia planned to keep PhysX all to itself. However, the company has confirmed that it’s going to stick by its guns, by making PhysX a free API that’s available to anyone.

Nvidia’s director of product PR for EMEA and India, Luciano Alibrandi, told Custom PC that ‘We are committed to an open PhysX platform that encourages innovation and participation,’ and added that Nvidia would be ‘open to talking with any GPU vendor about support for their architecture.’

As well as this, Alibrandi also promised that the free PhysX SDK would continue to be available to game developers. ‘We plan to continue supporting all key gaming platforms, including the PC and all next-gen consoles, with free PhysX binaries,’ said Alibrandi. He also added that Nvidia planned to make this a ‘continually improving set of tools in an open development platform that encourages leading-edge partners to extend the PhysX eco-system.’

Nvidia is currently working on implementing PhysX into its CUDA language, which is supported by all GeForce 8-series GPUs. When this is ready to go, Alibrandi said that owners of these GPUs will ‘simply need to download the CUDA PhysX drivers from Nvidia,’ and that ‘hardware acceleration will then be transparently supported for applications making use of the PhysX SDK.’

Nvidia plans to support PhysX in a number of ways, and Alibrandi says that these ‘could include both single and SLI based options.’ He also confirmed that Nvidia’s relationship with Havok is now over, saying that ‘we are 100 per cent focused on enabling CUDA-based GPUs to accelerate PhysX processing.’

If you’re one of the rare owners of a PhysX card, then you’ll be pleased to know that Alibrandi also confirmed that Nvidia would ‘continue to support the PhysX processor as demand dictates,’ although he said that CUDA-enabled GPUs would ‘outperform the PPU,’ Interestingly, when we asked if Nvidia would finally reveal the details of the inside of the PhysX chip, he replied: ‘Maybe.’ Ageia was very secretive about the inner workings of the PhysX chip, and we’d love to know what was inside it.

Either way, it looks as though there’s hope for AMD / ATI getting a bite of the GPU PhysX pie after all; the guys at AMD just need to decide whether they want it.



Evet arkadaşlar Nvidia Ageia psysics desteğini açık bir API haline getiriyor. İlginç bir gelişme.

!!!Nvidiadan destek hazır.Fizik desteği yakında elimizde.140oyun destekleyecek.
Nvidia, bu senenin başında Ageia'yı satın aldığı zaman şunun olması kaçınılmazdı: Nvidia PhysX API'sini donanımdan bağımsız hale getirip CUDA (Compute Unified Device Architecture) programlama arayüzüne uyarlayacaktı.

Aradan iki ay geçti ve Nvidia uyarlamanın tamamlanmak üzere olduğunu duyurdu. Bunun anlamı şu ki yakında GeForce 8 ve 9 serisi ekran kartlarına sahip olanlar sadece ilgili yazılımı netten indirip kurarak, ancak bir fizik kartının tanıyabileceği ayrıcalıklardan fizik kartı olmadan yararlanabilecekler. Teknoloji henüz kullanıma hazır olmasa da tam 140 adet oyunun buna destek sunması bekleniyor. PhysX'in GPU içine gömülmesi sayesinde özellikle fizik işlemlerini yoğun olarak gerektiren patlama ve parçalanma gibi olayların gerçekleştiği anlarda kare hızları düşmeyecek, hatta başarım artışının yanında daha gerçekçi fizik etkileri oluşturulabilecektir.


Evet arkadaşlar. Desteğin sağlanmasından da önemlisi 140 oyunda bu desteğin kullanılacak olması. Nvidia kart sahibi arkadaşlarım. Yaşadık galiba Dx10.1 den çok daha büyük bir avantajımız olacak gibi gözüküyor.

Bazı 780G çipsetli anakartlar 125 wattlık işlemcilerde sorun çıkarıyor. Alırken dikkat!!
Evet arkadaşlar yanlış okumadınız. Anandtech sitesinin yaptığı testlerde gördüğü bir durum. X2 6400 ve Phenom 9850 işlemcileri çoğu anakartın stabilite problemleri yaşamasına ve hatta bazen çalıştırmamasına ve çökmesine neden olmuş.

Anandtech anakart firmalarının Cpu Support Page bölümlerinde bu durumun belirtilmemesinin yanlışlığından bahsetmiş. Ve bu güçteki işlemcilerin bu anakartlarda çalışmayacağını söylemiş anakartların hiç desteklemediğini söylemiş.

Suçlunun 780G çipseti olmadığını. 3 ve 4 fazlı gerilim düzenleyen anakart tasarımları olduğunu söylemiş. Ama neredeyse bütün 780G taşıyan anakartlarda bu durum mevcut görünüyor.

Bu işlemcilerle sorun çıkartacak anakartlar:

Gigabyte GA-MA78GM-S2H

Jw RS780UVD-AM2+

Asus M3A78-EMH HDMI

ECS A780GM series ( Atx ve Mini Atx versiyonları)

Ayrıca Asrock, Jetway, Biostar



Ayrıca anakartların belli güç düzeyinin üstüne çıkamamalarından dolayı diğer işlemcilerde de Oc. konusunda sorun çıkarabileceğinden bahsedilmiş.

780G çipsetli anakartlar alıp bu tarz işlemcileri kullanmak isteyen. ( Veya kullanacağını düşünen kişiler alırken bir daha düşünsün).
