NVIDIA: DLSS 3 could well land on older generation RTXs!

The advanced exclusivity of DLSS 3.0 with graphics cards overpriced RTX 40 might not be a foregone conclusion.

The door was in any case opened by Bryan Catanzaro, Vice President of Applied Research on Deep Learning at NVIDIA. But there is a bone.

Deep Learning Sensitive Subject

The RTX 4080 and 4090 presented this Tuesday have already caused a lot of ink to flow. Both on their exorbitant price and on the fact that they will obviously be the only generation of NVIDIA graphics cards to support DLSS 3.0.

The new version of the technology powered by AI indeed intends to boost performance even more on cards that are already naturally more powerful than the previous generation. It’s hard not to see a purely interested gesture from NVIDIA, forcing performance enthusiasts to acquire an RTX 4000 model, the previous generation having already been more or less left aside by the chameleon brand.

However, the famous DLSS 3.0 could make its debut on the RTX 2000 and 3000, according to Bryan Catanzaro. He shared his pride in the work accomplished by his teams on this technology, and took the opportunity to answer a few burning questions.

A hope to be taken with tweezers

According to the Vice President of Deep Learning Research at NVIDIA, DLSS 3.0 needs the boosted Optical Flow Accelerator (AFO) of the Ada Lovelace architecture to deliver smoother, higher-quality rendering.

Note, however, that AFO has been around since the Turing architecture, used on the RTX 2000s. Bryan Catanzaro thus indicates that the application of DLSS 3.0 on previous generations of RTX graphics cards would be theoretically possible, if researchers and engineers put the hands-on.

However, he tempers the hopes of those who do not intend to lose a kidney for an RTX 4000 by specifying that DLSS 3.0 would not be as effective on previous generations. AFO has apparently been improved so much on the upcoming generation that DLSS 3.0 would have the opposite effect as sought on the RTX 2000 and 3000.

DLSS 3.0 would also currently have latency issues. This is offset by support for NVIDIA Reflex, the proprietary anti-latency technology. We find quite ironically here a form of vicious circle: the DLSS compensates for the violent drops in performance of the very greedy RTX, and Reflex compensates for the latency problems of the DLSS.

Anyway, pending a possible joint effort to optimize DLSS 3.0 on the RTX 2000 and 3000, games supporting this technology will always offer the DLSS 2.0 and Reflex combo for the latter.
