NVIDIA's DLSS 3 Can Theoretically Work on Older RTX GPUs

It wouldn't, however, provide as much benefit.

Two days ago, alongside other technological advancements revealed by NVIDIA, the company also presented DLSS 3, the third generation of the company's AI-powered performance multiplier designed to boost performance while maintaining great image quality and responsiveness. And although many developers, including CD Projekt, Techland, Unity, and Epic Games, quickly decided to introduce the technology to their projects, many regular gamers started wondering why this technology has to be exclusive to the upcoming RTX 4000 series.

In a recent Twitter thread started by Vice President of Applied Deep Learning Research at NVIDIA Bryan Catanzaro, the developer addressed such questions, stating that it is actually possible to run DLSS 3 on older RTX GPUs after some tweaking. However, neither games nor apps won't benefit much from the downgraded Deep Learning Super Sampling because the technology utilizes the Optical Flow Accelerator, which has been significantly improved in Ada over Ampere.

Without the improved optical flow acceleration it's likely you'd run into visual artifacts like you see when using motion interpolation on a TV.

There doesn't seem like older gpus have enough tensor core performance to actually make it worth implementing. If you can't generate a dlss 3 interpolated frame significantly faster than you could just render a real frame then there's no point.

I really hope Nvidia do this research... There are lots and lots of folks that only now got an RTX 30 card just to have this bad news. I thought only Ada had the OFA... So if Ampere also has it, but of course a scaled down version, I don't see why doesn't make it also DLSS 3 compatible. Maybe we can get this by modders anyway... Lets wait and see.
