However, those are really hard to notice during regular gameplay. If you've ever wanted to play games at 4K, 144+FPS with all graphics settings turned to the max, RTX 4090 and DLSS 3 can easily deliver that.Īs first noted in Digital Foundry's initial hands-on with the technology, the Frame Generation component can sometimes introduce artifacts. That's mostly because the RTX 4090 is a beast of its own, delivering substantial performance gains over the previous generation's top cards even when using DLSS 2 or native rendering.
When tested in titles that already run at very high frame rates, its boost compared to regular DLSS 2 is more limited (at least when using the Quality preset - I reckon the Performance and Ultra Performance preset may widen the gap). As such, its true potential will be unlocked with tomorrow's games.
As such, NVIDIA claims that in every two frames, only one-eighth of the displayed pixels were rendered normally, while the rest were reconstructed between Super Resolution and Frame Generation, delivering massive frame rate improvements.Īs NVIDIA noted during its presentation of the technology, DLSS 3 can really supercharge performance during CPU-bound scenarios like Microsoft Flight Simulator as well as in the most advanced ray traced games. The generated frame sits in-between frames reconstructed with DLSS Super Resolution. However, as previously explained by VP of Applied Deep Learning Research Bryan Catanzaro, the new graphics cards are equipped with a significantly faster and more advanced version of the OFA, which is why DLSS 3 is currently an exclusive of GeForce RTX 4000 graphics cards. Optical Flow Accelerators have been available in NVIDIA GPUs since the Turing architecture. There is now a new DLSS Frame Generation convolutional autoencoder that generates an entire frame on its own based on optical flow fields calculated with the Optical Flow Accelerator.
However, with DLSS 3, NVIDIA is taking one step beyond DLSS Super Resolution. The new GeForce RTX graphics cards are equipped with fourth-generation Tensor Cores, which include a new 8-Bit Floating Point (FP8) Tensor Engine, increasing throughput by up to 5X to an estimated 1.32 Tensor-petaFLOPS on the RTX 4090. First things first, though, let's take a look at what's behind the hood. Now that the GeForce RTX 4090, the flagship GPU (at least until the inevitable Ti model) and also the first from the brand new Ada Lovelace architecture to launch, has been in reviewers' hands for a while, we've been able to verify just how much DLSS 3 supercharges performance.
