AMD criticized NV Gameworks "Destroy" "Witcher 3" A card performance

2025-02-06 06:30:10|Myriagame |source：minecraft skins

The two recently released games have been trapped in the vortex of controversy- "Racing Plan" developers twice standing up to rumors for NVIDIA PHYSX special effects, and "Witcher 3" caused poor performance of A card because of the use of NVIDIA's Gameworks special effects.In these two games, there is no problem with the NVIDIA graphics card. Although some netizens are upset for AMD, the most torment is AMD. No matter what, the performance of the A card game is not a good thing for AMD.AMD executives also accused Nvidia's Hairworks special effects that destroyed the performance of AMD graphics cards.

The saliva war caused by the PHYSX special effects of "Racing Plan" has not yet stopped, but it is the game "Witcher 3" that makes AMD scorched. It has a greater impact than "Racing Plan".Level.The ARSTECHNICA website interviewed Richard Huddy, AMD's chief game scientist, and talked about the cooperation between AMD and Witcher 3 developer CD Projekt Red.

Huddy said that AMD cooperated with them from the beginning, and they provided detailed feedback to developers in various ways.About 2 months before the game was officially released, Hairworks special effects began to join the Gameworks code, which was exactly it ruined our performance, as if this was the goal they pursued.

Richard Huddy's statement does not know what everyone thinks. At least from the perspective of AMD, they think that the previous cooperation was normal, but the developer also temporarily added a new code before the game was listed. The new code just caused the AMD graphics card to be injuredThis is ..... Anyway, this is in line with the guess of conspiracy theorists.

Let's not care about the resentment between the developer and AMD and NVIDIA. We only see what the effect of AMD's HaiREWORKS special effects.There are many performance tests for "Witcher 3". NVIDIA has released a very detailed test before the game is released. Compared with the effects of different special effects on the performance of the game, it is limited to N cards, and the HardwareLuxx website has also measured special effects such as haierworks and other special effects.The impact on AMD and NVIDIA graphics cards, look at it.

The number of frames when the GTX 980 opened and closed Haireworks was 62.2 and 87.4fps, respectively. The performance loss was about 30%, and it was acceptable.FPS, performance loss was 61%.This special effect was not opened. The performance gap between the two sides still conforms to the previous test results, but after the opening, the performance of the R9 290X was only less than half of the GTX 980, and the gap was completely opened.

The root cause of this problem is actually technical -Hairworks special effects depend on the curved segment performance of the graphics card. The AMD and NVIDIA graphics cards are very different in the design of the curved segmentation unit.The new Polymorph Engine 3.0 unit, the number of polygonal units is twice the GTX 680, coupled with architecture improvement, the performance can reach 3 times the previous generation level.

Although AMD's R9 290X has increased compared to the previous GCN architecture, the geometric units in each group of CU units are increased to 4, but it is still worse than the GTX 980 overall.The performance of the unit has been significantly improved, and the official claim that throughput is 2-4 times that of the previous generation.

NVIDIA's Hairworks uses a large amount of curved surface segmentation, which makes the N card ratio with strong curved surface segmentation is more advantageous. AMD graphics cards are often dragged by high multiplied curved surface segmentation, and the performance decreases.Prior to this, NVIDIA also explained the problem of Gameworks, and also directly pointed out that the curved segmentation of the AMD graphics card caused performance differences.

Temporary solution of AMD graphics users

To this day, everything is too late to find the reason. What AMD can do is develop new drivers as soon as possible to optimize the performance of the game. The official has issued a notice that the new catalyst 15.5 driver will be committed to solving the performance of the "Racing Plan" and the performance of the Witcher 3.The question, Roy Taylor previously released the fastest this week.

Before the new driver comes, AMD graphics users can also temporarily solve this problem -to adjust the surface segmentation level of Wizard 3 separately in the catalyst control center, set it to 8X (the curved surface segment in the game can reach 64X)Essence
