AMD patented its alternative to NVIDIA’s DLSS on May 20, under the name AMD GSR”Gaming Super Resolution (GSR)”, formerly known as FidelityFX Super Resolution (FSR).
Remember that this technology is one of the most anticipated features of the year by all AMD users, as it allows doubling, tripling, and even quadrupling the FPS of a game without affecting the graphics quality of the game. Moreover, with the constant addition of new games to NVIDIA DLSS, the red team is starting to lag far behind in this aspect.
According to the US patent application, the AMD GSR would rely on crosstalk to scale images. The company explains that currently available approaches use linear scaling functions. However, this approach can result in blurry or distorted images because it does not take advantage of nonlinear information. In addition, AMD engineers claim that conventional neural networks are generalizable and are trained to work without significant knowledge of the immediate problem.
The company also claimed that this deep-learning approach does not take into account aspects of the original image, which can cause colors or details to be lost in the final image.
“The GSR architecture uses image densification and a combination of linear and nonlinear operations to speed up the process to a level usable for games. GSR renders images at a low-quality scale to produce high-quality image approximations and achieve high frame rates.
High-quality reference images are approximated by applying a specific configuration of convolutional layers and activation functions to a low-quality reference image. The GSR network approximates generalized problems more accurately and efficiently than conventional super-resolution techniques by training the weights of the convolutional layers with a corpus of images.”
For now, we can only wait for the red team to announce more details about this, such as the long-awaited release date. Let’s remember that DLSS 2.0 came in March 2020, while AMD couldn’t fulfill its plans to announce GSR before the Radeon RX 6000 launch (October 2020).
