AMD aims to catch up to Nvidia's DLSS with "neural supersampling"

Something to look guardant to: Thanks to its DLSS tech, which has go thing of a golden standard, Nvidia has ever led nan complaint erstwhile it comes to upscaling and denoising techniques for boosting capacity successful demanding ray-traced crippled scenes. But AMD hasn't been sitting idle – Team Red has steadily improved its ain FSR upscaling tech, and according to a caller charismatic blog post, nan institution is taking things to nan adjacent level.

The latest FSR 3.1 merchandise this twelvemonth brought importantly improved stableness complete erstwhile versions. However, there's still room for betterment pinch denoising path-traced frames.

Path tracing, which uses raytracing for each lighting calculations, is hugely computationally intensive. To execute real-time way tracing performance, nan number of ray ray samples calculated per pixel has to beryllium drastically lowered. There's conscionable 1 shortcoming: it introduces sound successful nan shape of incomplete illumination information that needs to beryllium cleaned up.

We've already seen really good Nvidia's DLSS handles games for illustration Cyberpunk 2077 and Alan Wake II pinch way tracing enabled, acknowledgment to techniques for illustration Ray Reconstruction to region sampling noise. Meanwhile, AMD seems to trust much connected game-integrated denoisers which do a satisfactory occupation but can't match Nvidia's AI-powered prowess. That's because, dissimilar DLSS, FSR does not trust connected AI aliases instrumentality learning. Instead, it uses a operation of spatial and temporal upscaling.

That whitethorn alteration soon based connected a caller AMD post. It says nan company's existent investigation efforts are centered astir enabling real-time way tracing connected its RDNA GPU architecture utilizing AI neural networks.

Specifically, nan invention AMD is moving connected is simply a azygous neural web exemplary that combines upscaling and denoising into 1 measurement – simultaneously reconstructing complete segment specifications while besides removing noise.

"We are actively researching neural techniques for Monte Carlo denoising pinch nan extremity of moving towards real-time way tracing connected RDNA GPUs," notes nan company.

The extremity is to alteration "a neural supersampling and denoising method which generates precocious value denoised and supersampled images astatine higher show solution than render solution for real-time way tracing pinch a azygous neural network."

There's nary denotation of erstwhile we tin expect this exertion to travel out. It's besides unclear if it will activity crossed each RDNA generations aliases conscionable connected early RDNA 4 and newer GPUs. The astir apt script is that this neural denoising magic whitethorn beryllium portion of an FSR 4 release, possibly moreover successful a constricted form.

Also chartless is precisely really AMD plans connected implementing it. So far, FSR's biggest trading constituent has been its cosmopolitan compatibility, but this could alteration if nan characteristic requires circumstantial RDNA hardware. Nonetheless, if it each pans out, a early type of FSR could thief AMD yet drawback up to Nvidia's DLSS.
