Multi-frame technology is simply accessible for RTX 5000. Nvidia’s DLSS chief is now opening up the chance that common body technology might additionally run on older GPUs sooner or later.
In the midst of CES 2025, Nvidia not solely offered the brand new GPU technology across the RTX 5090, but in addition launched the brand new model of its in-house AI upscaling with DLSS 4.
The catch: the function of DLSS 4 known as “Multi Body Technology”, which generates as much as three frames per intermediate picture calculation and thus guarantees a considerably larger body fee per second, will likely be reserved completely for the brand new graphics playing cards.
Nvidia has already executed one thing comparable with the primary model of body technology, which got here onto the market with DLSS 3. This know-how might solely be used on the RTX 4000, however that might quickly change.
Nvidia leaves room for hypothesis
Nvidia’s Vice President of Utilized Deep Studying Analysis, Bryan Catanzaro, lately answered questions from Digital Foundry in an interview.
Along with an fascinating deep dive into the brand new DLSS 4, the query was additionally raised as as to if body technology on GPU generations just like the RTX 3000 can be technically potential. Catanzaro commented as follows:
I believe it’s primarily a query of optimization, engineering, and in the end the last word consumer expertise. We’re introducing one of the best multi-frame technology know-how with the RTX 50 collection, and we’ll see what we will get out of older {hardware} sooner or later.
With that, Catanzaro opens the door a crack for retroactive body technology assist for RTX 3000 (and possibly even older GPUs), even when the Nvidia govt couldn’t be drawn to present a particular reply.
The stumbling block for these thoughts video games was a earlier query in regards to the elementary change that Nvidia is making to its upscaling know-how in the midst of DLSS 4.
As a result of as an alternative of counting on the so-called “Optical Circulation” {hardware} accelerator (OFA), DLSS 4 makes use of the tensor cores of the GPUs and can also be supposed to make use of much less video reminiscence.
To this point, Nvidia has argued that older architectures reminiscent of Ampere and Turing don’t have adequate OFA efficiency to assist body technology know-how.
In principle, the Catanzaro assertion opens up one other state of affairs: Multi Body Technology ought to – supplied that solely a sufficiently excessive tensor efficiency is definitely required – additionally be capable of run on high-end GPUs of the RTX 4000 collection.
Nevertheless, it’s uncertain that such a step will likely be taken, no less than for the following few months, as a result of from a market technique viewpoint, it could be capturing itself within the foot when the RTX 5000 technology is launched.
So the probably state of affairs can be one through which the change to tensor cores as the premise for upscaling would equip older graphics playing cards as much as the RTX 30 with the “first” model of Body Technology.
A “feasibility research” for this has been supplied not least by AMD, which has additionally been fielding an FG variant because the introduction of FSR 3 – and is unlocking it open-source for all FSR-3-compatible GPUs.
