It is simple:
Show us, that nVidia had a), despite their claims, access to the source code of Tomb Raider with the "ultra settings" and b) that AMD released the source code of TressFX before the 06.03.2013 (release date of Tomb Raider).

The main difference with TessFX and gameworks is what happened after they committed the "crime". AMD did provide source code and Nvidia hasn't at any point done so, to AMD that is. They provide it to the developers that pay extra but AMD doesn't have access and its being blocked by contract. This makes optimising it extremely difficult especially when Nvidia is releasing updates all the time and near release.

Something like OpenFX is the right call for the industry, they all need to get together and develop a middleware library that works across all cards (Intel included) for these sorts of high effort fancy effects that are generic approaches applicable across engines.

BTW re- Richard Huddy "Gaming Scientist":

Scientist is the guy that tells it as straight as possible, with no love for anything else than for his problem and problem-solving.
Scientist will advertently or inadvertently cause problems for his employer/company because he has no loyalty for anything but the truth.
This is why company rarely gives him the microphone, and why there is a job for public relations guy.

Now I'm not saying that Huddy is not scientist, but first and foremost he's AMD's gaming scientist.

Code:
I've spoken with Richard Huddy many times in the past, and the one thing that stuck -- always contradict and question what this man says.

The video is a oneside view of the story. It couldnt be more biased. So its worrying in the term of source critisism that you blindly believe it.

AMD does exactly the same as nVidia.

Huddy knew there would be people who doubted him. He put the ball in nVidia's court by challenging them to show he's lying. If he's lying then all nVidia has to do is deny it.

It is amusing that the mouthpieces for AMD are all 100% marketers and none of them are software developers. I find it amusing how these marketers are stuck on source code. AMD doesn't give this stuff out for Mantle. They outright stated that Mantle will not be available to other IHVs, and they blame that on DX12 supposedly. True? Double standard? I don't know, but highly amusing nonetheless. Software engineers on all sides have collaborated this fact from intel and NV, that source code is not a requirement for GPU optimizations for specific features or games. Oddly enough, how many AMD GE games has NV gotten source code from? I'm guessing a number between zero and negative one.

Furthermore, John McDonald who works at Valve software, specifically stated (and he IS A SOFTWARE ENGINEER AND NOT A MARKETER) that source code is not needed for GPU driver game or feature optimizations. And this Huddy guy is still stuck on gameworks which only uses HBAO+ in Watch Dogs. I don't get it. Apparently AMD created GPU optimizations for HBAO+ because the performance hit for using it is 100% identical between NV and AMD.

More intentional muddying of the waters by marketers. What AMD truly does best. The software engineers will tell you -- you don't need source code for optimization. Fact of the matter is, nvidia and AMD never get source code, or rarely if so. They can create performance optimized drivers nonetheless.

As much as AMD likes to portray themselves as saints to the media, fact of the matter is that NV and AMD basically both hate each other. It's competition at its best. AMD GE games have had lockouts for NV (and NV still made game optimized drivers) and perhaps vice versa happened. The difference: AMD talks through marketing, Nvidia talks through getting stuff done. Personally, I prefer the latter approach of not playing victim and whining/muddying the truth to the media, I don't think NV did that when the entire TressFX thing with Tomb Raider happened. They just fixed it without playing the blame game.

That patch released yesterday and did nothing. The game is still a wreck and performs abysmally even on the best hardware.

I was thinking about Watch Dogs and gameworks when I had time to watch this. If nvidia is sending out these .dll files without providing sources, it would be funny if it turns out the stuttering disaster that is Watch Dogs has the gameworks implementation in it to thank for it...

He is a spindoctor. Rhetorics is his game.

The only gameworks feature in Watch Dogs is HBAO+ and that is it. There is nothing else in the game using NV stuff aside from features requiring CUDA, such as TXAA. Everything else belongs to Ubisoft.

By the way, the performance penalty for HBAO+ is even between similar AMD and NV hardware.

Anyway, I don't even know how to feel about Ubi anymore. They intentionally hid the high resolution graphics for Watch Dogs in the game files and did not enable them. The VRAM situation in Watch Dogs is also truly hilarious because it does not look better than some DX9 games. Hopefully this isn't going to be par for the course at Ubi, because if so, screw them.

was that Tomb Rider... I think it was

anyway the game was a mess on GeForce when released.
so much that Nvidia made public apology. (but not THAT public like latest AMD's outcries)
they said they got the game build too late (notice no source code even needed). But they accepted full blame.
No blame game, no full blown paranoia, AMD did this, AMD did that...

although my memory could be wrong.
it could have been some other game, with Nvidia saying it's all Rory's fault, and telling us to go $#@ ourselves

Nvidia generally refusing to comment on anything amd can be frustrating too, but I guess it's better than having guys like huddy and hallock.

They both use mouthpiece marketers like this. Every time nvidia releases a new GPU line pcper has a marketing shill from nvidia there lavishing their latest product with praise. This is nothing new.

Take a look at the video they did when Titan released. I get why pcper would only ask the AMD marketer some challenging questions, they're - or at least that one guy who does all the gpu reviews - heavily nvidia biased, but it would be nice to see that done both ways when the opportunity presents itself. But that video from the Titan launch was just offensive. This shill from nvidia is there and the guy from pcper is basically cupping his.. the whole time.

The TitanZ video was priceless. Listening to him try to find something, anything, positive about the card was good for a laugh. He wound up going with 'TitanZ is nicer to look at' Had to turn it off about 5 minutes in.

Anyways, I like seeing this sort of thing. It's good when they go at each other and hopefully helps to keep them both honest. They've been going back and forth with manipulating games via dev influence for a long time. This is nothing new.

Ryan Shrout is Nvidia biased? Are you kidding me?
(Did you smell the sarcasm in my sentence?)

I really don't like that guy or his website, everytime I see a news article from him, I'm prepared to see some AMD bashing or some nVidia praising. It's getting pathetic.

But if you sit Ryan Shrout in front of Tom Petersen, you have a nice little lovely couple there.

I watched the whole interview and the Gameworks part has overblown on the forums as far as I am concerned. Ryan specifically asks him if the scenarios he mentioned are actually happening right now or is it just something AMD is afraid could happen in the future. The latter is true.

Perhaps people should actually listen to the interview rather than spread FUD around the interwebz.

As a whole I think the interview was quite good, Huddy gave the impression that he knows what he is talking about and not just some PR speak. At least that's how I see it.

As for Ryan Shrout I think you guys are going too hard again.. Specifically in the Titan Z video he does try to find positive things about it but ultimately the verdict is not in favour of the card. Just read the conclusion on Titan Z review.. pretty much no recommendation except for very specific scenarios.

They even make fun of Titan Z on their podcast.. hell, Pcper is actually the only major site that actually reviewed the card and since nVidia is apparently not giving them away they probably bought it themself. So kudos to pcper!

Check how he is mocking the R9 295x2 but notice how he praise the Titan Z TDP.

at the time I watched it
3500 views = good odds's on winning a card
had this been nv - 3.5 mil. views might have been there for free cards.

but what peeps are not saying
- has amd gpu's and amd's gaming focus improved , I think yes .

if so maybe the cooler screw up's like on the 290's might not happen again if a gaming focus over sight is now in place , rather than a cpu cooling department where 110c is ok on a 40 watt cpu with a stock cooler. given their last release vs nv 2 x cards we all know how that turned out , future might not give nv a unlimited nv tax on their cards.
but it all come's down to the card reviewers, imo

I'm pretty sure I saw Ryan cringe several times during the Huddy interview. But to his credit he kept things professional and asked good questions.

Listen to the interview. You'll find Huddy categorically disagrees/denies with most of what you have posted above as fact, or much of your interpretation is just wrong. Keep in mind this is all on the record. If he misstated anything we'll know pretty fast, I'm sure.

Also, PCPER is not friendly ground for AMD. Many of the complaints you have about AMD complaining were direct responses to questions put to him. Questions that were intended as tough questions.

I'm pretty sure I saw Ryan cringe several times during the Huddy interview. But to his credit he kept things professional and asked good questions.

You mean like when Huddy forced him to say it was the fastest card in the world.

But on the other hand these people go out and lie to everyone about stuff.

Now people think that AMD would never put features into games which hurt the a)performance (lol) and b) would hurt the competition more than them (lol).

Forward+, HDAO or TressFX costs more performance on nVidia hardware than on their gpus. Especially Forward+ is a good example:
http://www.hardware.fr/articles/869-14/benchmark-dirt-showdown.html

A GTX680 loses more than 50% performance and AMD blamed nVidia's hardware instead of their work with the dev:
However, it certainly seems to the case that (consumer) Keplar is not great for Compute, which is still a curious choice given the interests in DirectCompute by developers. That interest is only going to ratchet up further now as well.

That the performance hit is a result of the Kepler hardware design decision and not the implementation of the feature.

He's talking about implementing features that run poorly on both brands not just AMD's According to Huddy the Hair Works in COD, for example. Tressfx would run ~4X faster on nVidia hardware than the Hair Works effect does. It's just that it runs ~30X slower on AMD hardware. (Forgive me if I haven't remembered the exact quote after listening to 3 hrs. of Huddy interviews, but I think I'm right on those figures.)
