An Nvidia engineer explains how and why.
Deep Learning Super Sampling 3.0 is one of the most interesting features that Nvidia presented during the recent announcement of graphics cards from the RTX 4000 family. DLSS 3 was supposed to work only on the latest chips, but it seems that the matter is not entirely settled.
” DLSS3 relies on the optical flow accelerator, which has been significantly improved in Ada over Ampere – it’s both faster and higher quality ,” wrote Bryan Catanzaro, vice president of artificial intelligence research, Nvidia.
“ The accelerator has been around in the GPU since the Turing days , but in Ada it’s much faster and that’s what we rely on for DLSS3. Customers with RTX 2000 and 3000 series would feel DLSS 3 lagging, producing poor image quality and not improving performance , ”he continues.
“ It is theoretically possible that with additional research and engineering , we could make this technology work on other cards , even though it would not be as beneficial. The current version only works on cards from the 4000 ”series.
The engineer’s statement leaves the door open for later implementation of the technology on older systems, although you should not expect such results as in the case of the latest RTXs.
