AMD: NVIDIA Crippled Hairworks performance On Our Cards

September 30, 2014 - 12:32am

One of the technical highlights of last year's Tomb Raider reboot was AMD's TressFX hair renderer which gave Lara a beautiful, physically-animated ponytail for the first time in her life.

AMD is now preparing for TressFX 2.0 debut with Lichdom: Battlemage, but not before pointing fingers towards NVIDIA's implementation of its own Hariworks hair rendering technology. According to AMD, TressFX performs exactly the same on both companies' cards while Hairworks is 7 times slower on AMD's cards for no technical reason.

TressFx 2.0 come with the following improvements:
• New functionality to support for grass and fur
• Continuous levels of details (LODs) are designed to improve performance by dynamically adjusting visual detail as TressFX-enabled objects move towards and away from the player’s POV
• Improved efficiency with many light sources and shaders via deferred rendering
• Superior self-shadowing for better depth and texture in the hair
• Even more robust scalability across GPUs of varying performance envelopes (vs. TressFX 1.0)
• Modular code and porting documentation
• Stretchiness now respects the laws of physics

Punk *** *******

Nvidia

Nvidia can **** off and die for all i care. i had a Nvidia card once and that burnt out within the warranty time and Nvidia didn't give me back my money cos the card was "miss used" what ever the **** that means. hope ISIS rapes you.

You need help friend!

Actually... TressFX sucked on Nvidia cards

When Tomb Raider came out, TressFX was a huge cause of crashes and slow downs on Nvidia cards, and it took Nvidia a long time to get the game working correctly. So AMD can shut up.

tressFX as all Radeon SDK

tressFX as all Radeon SDK effects are open effects distributed in source code, so NVidia can easily review and optimize drivers for it (they often not capable to do so but thats another story). GameWorks on the other hand fragment PC platform as its black-boxed, closed, distributed in encrypted DLLs! Therefor noone can ever optimize drivers for it but NVidia. So next time pls blame Nvidia not AMD as NVidia can optimize but for GameWorks performance is responsible Nvidia only as noone else can review and optimize drivers for it!

Drune, you're quite right

not only what you say is true, mantle doesn't work with nvidia graphics cards and harms, in some situations, the performance of intel processors (check mantle reviews with intel processors, intel processors with dx11 has better performance than intel processors with mantle). read my (HG-88) previous comment, to view the problems I had with a Radeon R9 290x.

Mantle is fully multithreaded

Mantle is fully multithreaded scalable API, not like DX that is single-threaded bound! For that simple reason MANTLE will always benefit multicore CPU! any CPU, same as DX12 will benefit all multicore CPU. More cores more performance boost. I know lot of people cannot handle that after 10 years we finally got API that can properly handle multicore CPU but pls deal with it!

always the same crybabies

AMD instead of ******** about nvidia, why dont you improve driver support, build quality, energy usage in your cpu's (which is rubbish, the AMD FX-9590 in some situations uses 2 times more energy for the same performance of the core i7 4770k (i own one) and tech support (unofficial patch to solve some of the problems of my R9)). I made the mistake of spending 579,00 € on a brand new Asus R9 290X DCII OC when it was released in my country, from day one worked poorly (BSOD and other graphical problems, it wasnt a ASUS problem it was AMD problem), and the worst is that it took an unofficial patch to solve some of the problems my R9 had. For this reason, I sold it for the same price, and with the money I earned, bought the 609,90 € ASUS GeForce GTX980 (i bought it last week and willingly payed the 30,90 € more) which from day one worked without any problems. Before megagames users say something, i'm not a nvidia fanboy (i currently have 4 GC, the fx5200 (very old pc dual 98/xp OS), the GTx 480 (which i had before buying the R9), the gtx980 (gaming pc dual 7/8 OS) and the Radeon HD 4650 (mini-itx pc)).

If you happy with black boxed middleware that cannot be reviewed that fragments strong PC platform and therefor it hurts it then you will call that ********. All the rest know it is concern about platform that AMD make living on. Nvidia can also easily optimize gameworks for only new architecture making you buy the new GPU every year. And they does that with ubisoft pretty visibly.

Why use something that makes

Why use something that makes use of Nvidia tech specifically? That's like AMD bragging about Cuda or every other game that runs a three second ad screaming Nvidia on launch.

They make these stupid

They make these stupid proprietary techs to appeal to devs, not gamers. Dev studios don't work on their own, they get support from intel, nvidia, amd and others when it comes to graphics and hardware optimizations. There was a blog post by a dev a couple of months ago about the current situation of OpenGL drivers for example, it explains about the available drivers and how much support you get from the three companies (company A, B and C, but you can tell which is which) who dominate the consumer graphics market. Also dev support isn't free.

What does your last point

What does your last point about OpenGL have to do with your main point? Your right about dev support not being free, however lets say GL were to die. What other graphics library could they implement or would they implement one. Directx success has been built up and arrowed GL, losing it would imply MS has something better. Which I really doubt unless these companies are anti competitive, free software can't die they could theoretically drop support but not without severe ramifications to both their hardware and consumer base.

I Agree Nvidia Did Cripple Hairworks

Nvidia don't like sharing there features with ATi, And clearly ATi made TressFX work exactly the same for Nvidia ATi played fair,

It's how you compete

Stupid thing to get uppity about, it's competition. You just have to remember that the consumers, the people paying for these products, are the victims in the end. Companies don't give a **** about customer satisfaction or making a great product, they care about creating something you 'can't live without' at as close to zero cost as possible and they'll do WHATEVER they feel they must to ensure that. Making their product run shoddy on another persons platform is just business sense.

Nope, it's not business sense

Nope, it's not business sense, it's anti-competitive. Likely illegal, but even if it isn't it's certainly outrageous and means we should stop buying Nvidia for a while to give them a dose of cold hard reality. Anything less means we're being complacent and deserve to be screwed over like this.

competition does not equal sabotaging

You're an idiot. It's another vicious move on the list by Nvidia to sabotage gamers that pay for games but are running on another hardware and you are not smart enough to have any compassion for this. If every one would think like you then Toyota being a leader in sales worldwide would have made cars that destroys the roads in a way that only their own brand could stand on a pavement.. and you'd be fine with this cause you're an idiot that doesn't care about customers buying another product than your own. If Nvidia would publish games on their own and decide to make them exclusive to their hardware, then you'd have a semblant of excuse but this?!! Seriously.. go fck yourself. Jerks like you are poisoning our society and gives it a bad name.
