"Witcher 3" Gameworks special effects argument that A cards cannot be used directly

NVIDIA's Gameworks tool can help game developers quickly apply NVIDIA's 3D technology to simplify development, but Gameworks's "black box" operation often puts developers into a vortex of controversy -it can only be optimized for N cards.Usually there is no normal experience.This time "Witcher 3" also uses Gameworks special effects. Developers said that they cannot optimize the code for the AMD graphics card. It is recommended that A card users better turn off Gameworks special effects.

Nvidia's Gameworks special effects are not only a temptation for game developers. It integrates Nvidia's Physx, TXAA, curved surface subdivision, HBAO+and Flameworks, Faaceworks and other tools, which can simplify development, but it is also easy to attract criticism. UbisoftIn the previous games, several games encountered such controversy, and even game developers were dissatisfied, because they could not see the code themselves, let alone optimize the graphics card.

The upcoming "Witcher 3" game also uses Gameworks special effects. The developer Marcin Momot recently said, "There are many people asking if we have opened the HAIRWORKS special effects of the AMD Radeon graphics card.It may not be satisfied with the performance of the RADEON graphics if it is not satisfied with the performance.

The developer's statement did not reveal the "black box" problem of Gameworks. The developer CD Project can indeed see the Gameworks source code, but even so, they cannot optimize the AMD Radeon graphics card to run normally.In fact, this function is not optimized on the A card, I am afraid it is not easy to run normally.

Gameworks's "black box" operation problem is already an old topic. NVIDIA has also vowed that they would never be black AMD, nor would they prevent developers from optimizing AMD hardware.After the "Witcher 3" caused controversy with Gameworks, the PCPER website also contacted NVIDIA. The company's PR business director Brian Burke also responded. He first emphasized that "NVIDIA will not ask for game developers to do nothing moral."

Then he explained the advantages and operations of Gameworks, which can help developers simplify development, but NVIDIA provides its source code to developers. If they are not authorized, they will not give their source code to others (PS: Under this limit, AMD is estimated to never have a chance).

Why is the A card that is so bad under the special effects of Gameworks? The next explanation is more critical. Brian Burke said that this is because AMD's graphics card surface subdivision (Tessellation) performance is not very good, and Nvidia is powerless.Using DX11 curved segmentation can make the GPU memory less, so multiple characters can apply hair and hair special effects at the same time.

He believes that (this happens) is actually a resource issue. NVIDIA spends a lot of art and engineering resources to make the Witcher 3 game better. He thinks that AMD can do the same thing because their agreement with the developer will not be the developer.Prevent them from cooperating with other IHVs (independent hardware developers, which also say AMD and Intel).

PCPER subsequently asked whether the rumors that "NVIDIA prevented AMDs from optimizing the optimization of Gameworks", Brian Burke said that AMD and CD Project are actually capable of optimizing, but they need different ways.Developers can change the surface segment density according to the architecture of different GPUs, but this requires AMD or CD Project to do special projects.AMD can also read the source code. They can make some changes at the database file level of the driver. NVIDIA specializes in engineers to cooperate with game developers. AMD can also do such things.In the end, NVIDIA reiterated that they could not stop developers from optimizing the AMD graphics card.

PS: At the time of "watching the door" Gameworks caused controversy, Xiaobian said that it would not be finished. Now "Witcher 3" uses Gameworks special effects, and it really causes the same problem.NVIDIA has also explained the operation process of Gameworks many times, and vowed that they would not do or ask game developers to do immorality.

Gameworks's performance on different graphics cards has technical reasons. As a technology developed by NVIDIA, it will definitely develop based on the NVIDIA graphics card architecture. AMD's graphics card architecture is different. NVIDIA focuses on the curved surface segment performance of AMD graphics card here (AMD has previously said that the curved surface segmentation technology was invented first).However, technical problems can still be solved. NVIDIA also mentioned this, so the key to this problem can actually be summarized as a problem -NVIDIA believes that he has invested resources to develop Gameworks. Why should AMD be enjoyed?
