Multi-frame era is just accessible for RTX 5000. Nvidia’s DLSS chief is now opening up the likelihood that common body era might additionally run on older GPUs sooner or later.
In the middle of CES 2025, Nvidia not solely introduced the brand new GPU era across the RTX 5090, but additionally launched the brand new model of its in-house AI upscaling with DLSS 4.
The catch: the characteristic of DLSS 4 referred to as “Multi Body Era”, which generates as much as three frames per intermediate picture calculation and thus guarantees a considerably larger body price per second, can be reserved solely for the brand new graphics playing cards.
Nvidia has already accomplished one thing related with the primary model of body era, which got here onto the market with DLSS 3. This expertise might solely be used on the RTX 4000, however that would quickly change.
Nvidia leaves room for hypothesis
Nvidia’s Vice President of Utilized Deep Studying Analysis, Bryan Catanzaro, just lately answered questions from Digital Foundry in an interview.
Along with an attention-grabbing deep dive into the brand new DLSS 4, the query was additionally raised as as to if body era on GPU generations just like the RTX 3000 could be technically attainable. Catanzaro commented as follows:
I feel it’s primarily a query of optimization, engineering, and in the end the final word consumer expertise. We’re introducing the most effective multi-frame era expertise with the RTX 50 sequence, 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 era assist for RTX 3000 (and possibly even older GPUs), even when the Nvidia govt couldn’t be drawn to offer a particular reply.
The stumbling block for these thoughts video games was a earlier query concerning the basic change that Nvidia is making to its upscaling expertise 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.
Up to now, Nvidia has argued that older architectures similar to Ampere and Turing should not have adequate OFA efficiency to assist body era expertise.
In principle, the Catanzaro assertion opens up one other situation: Multi Body Era ought to – supplied that solely a sufficiently excessive tensor efficiency is definitely required – additionally have the ability to run on high-end GPUs of the RTX 4000 sequence.
Nonetheless, it’s uncertain that such a step can be taken, a minimum of for the following few months, as a result of from a market technique perspective, it will be capturing itself within the foot when the RTX 5000 era is launched.
So the most certainly situation could 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 Era.
A “feasibility examine” 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.
