Along with saying the GeForce RTX 40-series (Ada Lovelace) graphics playing cards, Nvidia additionally revealed the corporate’s newest DLSS 3 know-how. With the chipmaker claiming as much as a 4X efficiency increase, DLSS 3 clearly acquired a number of consideration.
The million-dollar query is whether or not DLSS 3 will come to older GeForce graphics playing cards — and Bryan Catanzaro, Vice President of Utilized Deep Studying Analysis at Nvidia, has answered the query on Twitter (opens in new tab).
Catanzaro confirmed that DLSS 3, in its present state, solely works on the GeForce RTX 40-series graphics playing cards. The Nvidia engineer did go away the door open for backwards compatibility, stating that it is theoretically doable to get DLSS 3 engaged on earlier technology GeForce graphics playing cards, such because the RTX 30-series (Ampere) or RTX 20-series (Turing) choices. Nonetheless, Catanzaro believes that DLSS 3 will not supply a lot profit for homeowners of legacy GeForce graphics playing cards.
Nvidia’s DLSS 3 know-how depends on the Ada’s fourth technology Tensor cores and the brand new Optical Move Accelerator (OFA) to work. OFA is not some new invention that Nvidia not too long ago cooked up with Ada. OFA has been current for the reason that Turing days. The distinction is that Nvidia has tremendously improved it in Ada versus Ampere, and it now delivers greater efficiency and higher high quality. The OFA in Ada is reportedly 2 to 2.5 instances sooner than on Ampere. Nvidia has seemingly made some algorithmic adjustments as properly.
Ampere and Turing can theoretically leverage DLSS 3, however they will not yield the identical advantages. Catanzaro stated that DLSS 3 doubtless will not increase body charges on Ampere or Turing — quite the opposite, homeowners would most likely expertise laggy gameplay and dangerous picture constancy.
DLSS is thought so as to add a point of latency. That is the principle purpose why DLSS 3 integrates Nvidia Reflex with the intention to ship greater body charges on the identical system latency. Nvidia claims that DLSS 3 is ready to scale back latency by as a lot as 2X when in comparison with the native latency. In a demo (opens in new tab) of Ray tracing: overdrive mode in Cyberpunk 2077, DLSS 3 along with DLSS Tremendous Decision, DLSS Body Era, and NVIDIA Reflex confirmed 4X greater efficiency and 2X improved responsiveness.
DLSS 3 has confirmed to be useful in CPU-intensive video games similar to Microsoft Flight Simulator. Nvidia’s demo (opens in new tab) confirmed DLSS 3 doubling the body charges in Microsoft’s title, which closely taxes the processor.
DLSS 3 will debut on October 12 alongside the flagship GeForce RTX 4090. Nvidia expects over 35 video games and functions to assist DLSS 3 at launch. Extra importantly, DLSS 3 builds upon the foundations of DLSS 2 so recreation builders can simply allow DLSS 3 on present video games that already embrace DLSS 2 or Nvidia Streamline. Portal RTX comes out in November as a free replace for current Portal homeowners.
