The Witcher 3 Dev says Nvidia HairWorks Unoptimizable for AMD GPUs

Nvidia’s GameWorks library, places in the hands of developers a collection of graphical tools, that can simplify game development. Although the fact that these libraries are closed  to most users makes it difficult to optimize for if you’re not using and Nvidia GPU.

CD Project’s Marcin Momot, released a statement claiming that Nvidia’s HairWorks code cannot be optimized to perform well on AMD GPUs;

“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.”

While it would be nice if Nvidia promoted fairness with their GameWorks library, benefitting the gaming world, with simpler game development, right now it’s actually promoting Nvidia over AMD.

Of course that’s not to say this is not understandable, they have every right to do so, as it’s their tech, they spent millions in research and development on these libraries, and they have some of the greatest minds in the field working for them. They aim to provide the best technologies for the PC Gaming crowd, and they do advance the format. Sharing the technologies with their competitors would certainly not be entirely beneficial, as it’s not only a matter of hardware vs hardware, the technologies being implemented are as part of the equation as the hardware is, and Nvidia are the ones responsible for developing them.

There is also the subject of market share which again gives Nvidia a huge advantage, therefore gathers most of the developers’ support. When AMD eventually releases their new GPUs, which will hopefully happen mid-late June, could help to balance things around a bit, and subsequently maybe somewhat alter the situation.

It would certainly be quite nice if AMD managed to gain some ground and have the ability and funds to create some alternative to Nvidia’s GameWorks libraries, that could gain the support of developers. Although optimizing for two different technologies would be less than ideal.

Lets just hope that AMD finds a workaround to the issue and release a driver update so that everyone can enjoy this great game at its best, regardless of their choice of hardware.

CD Projekt RED removed the “PS4 vs PC” comparison video, posted earlier by PCGamesHardware and went on to detail the differences between the two versions. They claimed that the PC build was not final and that the PS4 version dis not use the day-one patch which not only fixed the PS4 framerate issue but also implemented a few visual enhancements.

PlayStation Access has provided an in-depth look into many aspects of the game in a 46 minutes video which can be viewed here. It covers everything that fans have been asking for and provides answers to most questions without spoiling the experience.

A few gorgeous screenshots from the PS4 version have also been made available, and they reveal some quite beautiful vistas and the amazing lighting system.

From what we have seen so far The Witcher 3 certainly looks beautiful on all three platforms, and it will surely provide one of the greatest experiences of the year no matter the system of choice.

The launch cinematic which was made available yesterday looks amazing. CD Projekt has also revealed the changelog for the day-1 patch which can be viewed here.  docm77, has also made available a video interview with CD Projekt’s visual artist, Jose Teixeira, in which he shares his thoughts on the downgrade subject.

The Witcher 3 is just three days away from release, and as we have previously covered, CD Projekt has already announced that pre-load options are already live, as well as the unlock times for The Witcher 3.

The Witcher 3 will release on May 19 2015 for the PlayStation 4, Xbox One and PC. We will bring you any new information on The Witcher 3 as soon as it becomes available. Be sure to check out our previous coverage for more information on The Witcher 3, here and here.
