Looks like AMD have been on the money all along regarding Devs not being able to optimise Game Works for AMD..

Marcin Momot

CD PROJEKT RED:

Many of you have asked us if AMD Radeon GPUs would be able to run NVIDIA’s HairWorks technology – the answer is yes! However, unsatisfactory performance may be experienced as the code of this feature cannot be optimized for AMD products. Radeon users are encouraged to disable NVIDIA HairWorks if the performance is below expectations.

Hope this information helps.

Must have been Obtuse Friday, a non issue thread with denial, deflection, ignorance, bliss.:p

To be fair, having a NV propitiatory tech even work at all when a AMD card is detected rather than formatting your C: and replacing your bootsector with woodscrews.jpg shows NV are moving (glacially) in the right direction.

:D

Thought the CDR dev clearing up any confusion/Ndf denial and confirming the zero possibility of GW's optimization for AMD gpu's was clarity enough, but here we are.:D
 
Well, what can one say. If you're happy repeating failsafe corporate responses instead of discussing the issue properly there's no real reply to that comment, Tommy. Strange how seemingly that's been a trend since the new rules kicked in. Perhaps you have nothing to add then

Since new rules kicked in?

It's called cba getting into pointless discussions these days but you want an opinion, here you go:



You linked a corporate response a few posts ago, had zero issues with it, nothing to 'add' out with AMD Roy's public **** up and PCars apparently contains royalty free in game advertising.:D

GW's bottom line=Shady as **** artificial performance advantage over your competitor with a huge carrot encouraging them to switch vendors and at the same time a subtle push to ensure your own customers upgrade-yet another absolute genius tactic from Nividia-the company that doesn't do apologies to it's customers, simply explanations when they get caught out.:p

All we need now is for AMD to shake itself down, claw some business back with competition, loose the good guy image and lock out Nvidia optimisations on their features, sorted, the console ecosystem on PC-happy days.:D
 
This whole article is worth a good read and sums up my thoughts on what is what with NVidia and AMD.

GameWorks source code is available to licensees. We provide source code, under license, to developers who request it. Licensees can’t redistribute our source code to anyone who does not have a license.

Can you share what your take on that specific comment is?
 
Think pgi worded it perfectly humbug, more a case of 'that's your lot', although I think Nvidia will monitor it and if there's a big enough ruffle of discontent, they'll address it.


No problem. I see it as fair. I have a car and I let me friend borrow my car, I wouldn't be happy if he then let all his friends use my car. So nVidia have developed GameWorks for developers to use but not allowed to let others use who don't have permission. It cost time and money to develop these effects, which "can" be turned off if they don't run too well on other IHV's and it isn't compulsory to have them on.

What is your take on it?

It's more like kicking your mate out your car and making him walk to work in the ****ing rain because it's your car, totally justifiable as he doesn't have one but it's ok because you'll both get there in the end and it's a **** take anyway:p


'GameWorks source code is available to licensees. We provide source code, under license, to developers who request it'-CDR have access to the code, fine.

'Licensees can’t redistribute our source code to anyone who does not have a license'-CDR can't share the code.

'the code of this feature cannot be optimized for AMD products'-but the line is it's for devs to code in effects easily, if it's to make it easier for devs, why can't the devs help AMD getting a game feature optimised?

The 'giving away something for free' and the 'turn it off' lines are deflecting the issue.

In direct comparison, Nixxes worked hand in hand alongside Nvidia to enable fully functional TFX code and modified TFX code to work as it should-in an early patching/fix attempt, Nixxes even broke AMD TFX to the point that they gave BOTH AMD AND Nvidia two different versions to use, with working TFX on BOTH at the same time-and AMD didn't so much as blink an eye.

All TR TFX gamers regardless the gpu were winners.

Which ultimately gets a win win situation for Nvidia, it pushed me to the dark side.:eek::D

Let's face it, there are Nvidia fans here that will blame AMD and defend Nvidia and there are AMD fans that will blame Nvidia and defend AMD. One side is as bad as the other.

Sick to death of hearing about it being a 'blame game', it's **** for the PC gaming community.

Taking vendor preference out the equation, if you had the choice of the Nixxes approach or the black box approach, which one benefits the PC gaming community?
 
It was easy to understand considering all you were doing is relaying what you read happened. It's also the only example to date, because nobody has the kind of resources to coactively work like that unless there is money behind it.

It's the only example needed on how it should be played-above board with zero obfuscation involved from anyone.
 
lol gameworks added in the last few months.

Well here is a video from last August. (that is 9 months ago for those who cannot be bothered to work it out :))


And here is one from June 2013 ( that's a lot of months because I cannot be bothered to work it out. :))


So that pretty much shuts up any talk that Gameworks was only implemented in the last few months.

No it doesn't, that was the optimised Keplar build version, it got scrapped with updated GW's to favour Maxwell...

joke.
:p

Irrelevant. "AMD Optimized" is the default option in CCC. A new driver issued by AMD would have a lower tessellation level (Hence the whole "optimisation") which would then be the base tessellation level for the game as rendered by an AMD card.
That doesn't absolve Nvidia of any wrongdoing (But no reasonable debate can ever take place, because of dat elephant in the room).

Relevant because if AMD released a driver level override without any user input, the place would erupt.
 
I'm confused.

That's already the case. The default option is AMD optimized, not application setting.
Same as surface optimisation is ticked by default and texture filtering isn't at highest by default.

These are "optimisations" which can affect IQ without any user input.



Same applies, very much doubt it's as simple as a straight reduce tess performance by 75% without user input, fine 'tweaking' and outright performance advantage is two different entities.
