NVIDIA has acknowledged the problems with DLSS


Andrew Edelsten, technical director of Deep Learning, commented on criticisms of the DLSS (Deep Learning Super Sampling) process in a lengthy blog post. As is well known, NVIDIA refers to the anti-aliasing technique by this name, the essence of which can now be broadly summarized here by calculating the image to be drawn at a lower resolution and then replacing the missing information with artificial intelligence (Tensor cores). Based on experience so far, it looks like DLSS can deliver great speed, but the picture quality is detrimental - especially in Full HD.

Andrew Edelsten said that the feedback from the players and testers has been examined. The expert also noted that DLSS can only provide substantial benefits if the GPU load is high, but the game still does not run at a stable 60 FPS, and is also very beneficial when used at 4K resolution. The explanation of the latter is that Tensor cores generate the final image from roughly 3840-2160 million pixels at 3,5 × 5,5 pixels, even at 1920 × 1080 it can only be based on 1-1,5 million pixels. With less data, it is much more difficult to produce an optimal display, so at this point, programmers have no easy task.


Edelstein also revealed that for Metro Exodus and Battlefield V, fixes will soon be made that will make the display less blurred in addition to DLSS. At the former title, the expected improvement is mainly below 1080p, and at ultra-wide resolutions, at the latter at all resolutions.
