DLSS on 1080ti, possible or not? Explained.

Many of you have already heard of DLSS, but do you know what it is? The most important question is which video cards are supported by DLLSS? Does the 1080ti support DLSS?

GeForce GTX 1080ti today

Nvidia released GTX 1080ti on March 2017, from that day two generations of GPU has been changed. Unforgettable fact that the GTX 1080ti at its release time was a top-tier GPU, even now, video card outperforms such video cards like RTX 2070, RTX 3060 and can be compared to RTX 2080 or RTX 3070.

GeForce GTX 1080ti has an 11 GB of vram, which is very big for even today, for the fact RTX 3060 has 12 GB vram, but in many cases has worse performance. If you are not playing a game that has ray tracing capability, then the GTX 1080ti will always be a winner compared to the RTX 3060.

What is DLSS?

DLSS stands for deep learning super sampling, and from June 2021 the technology is available on GeForce RTX 20 and GeForce RTX 30 series GPUs. In traditional words – super sampling is a technique where you have a game running at a higher internal resolution than what’s displayed on your monitor. This is most commonly used as anti-aliasing to help remove jagged edges. So your monitor might only be 1080p, the game could be running in 4K. Gamers use this to create crisp, sharper looking image quality, but it requires beefy hardware.

So does DLSS works on GTX 1080 ti or not?

Nvidia claims that DLSS is only for GeForce RTX20 and GeForce RTX 30 series GPUs. DLSS on GeForce GTX 1080ti is possible, but performance would be TERRIBLE. 1080ti can run DLSS by software, but it does not have the required hardware.

DLSS requires special hardware, it only works on Turing tensor architecture cores.

Pascal cores and Turing tensor Cores

The GeForce GTX 1080 Ti is based on the NVIDIA Pascal cores architecture. And the new generation RTX cards have tensor cores, which can work with DLSS.

Nvidia’s RTX video cards that have ai-based tensor cores DLSS takes a target resolution and displays an image of that quality while using a lower base resolution.

That means if you can run games at 1440p, but starts to struggle when displaying at 4k, and you have a 4k monitor, using DLSS 1440p games will be reconstructed in real time to 4k at less computational cost.

Maybe DLSS doesn’t work on GTX 1080 ti, but AMD has developed an equivalent to DLSS which is called FidelityFX Super Resolution (FSR).

Nvidia DLSS vs AMD FSR

Nvidia DLSS and AMD FSR are two similar sampling technologies, but as we know, DLSS works only on RTX generation GPU. DLSS was released in February 2019 and AMD FSR in June 2021.

It’s obvious that FSR – fidelityFX super resolution is a different beast compared to DLSS. When AMD created FSR they set a goal that it will be an open source upscaling solution based on industry standards, which does not require any specialized hardware. For example DLSS works only on GPU’s which Tensor cores.

However, those two rendering techniques are similar, but works different. FSR works by patial upscaling using only the source image, DLSS supplies the neural network through several inputs: the source image, the motion vector, the temporary feedback from previous frames, and the results of its training algorithm.

From our perspective, DLSS has an improved anti-aliasing, image quality and handling of subpixel details compared to FSR. AMD FSR is easier to adapt to different GPUs and has less anomalous artifacting compared to DLSS.

AMD FSR on GTX 1080 ti?

Yes, it is supported on GTX 1080 ti, and on many other older GPU models.

GPU list that can support FSR

  • AMD Radeon 6000 Series
  • AMD Radeon 6000M Series
  • AMD Radeon 5000 Series
  • AMD Radeon 5000M Series
  • AMD Radeon VII
  • AMD Radeon RX Vega Series
  • AMD Radeon 600 Series
  • AMD Radeon RX 500 Series
  • AMD Radeon RX 480, 470 and 460 
  • AMD Ryzen desktop CPUs with AMD Radeon graphics
  • AMD Ryzen mobile CPUs with Radeon Graphics
  • Nvidia GeForce RTX 30 Series
  • Nvidia GeForce RTX 20 Series
  • Nvidia GeForce 16 Series
  • Nvidia GeForce 10 Series (GTX 1080 ti as well)

Example of FSR performance

AMD FSR can show fascinating results on GTX 1080 ti, by upgrading FPS results from 93 avg FPS to 120 avg FPS on Resident Evil 8.

Despite the fact that FSR is still a fresh thing, games which have this option can be found.

As you can see, the list of games is definitely not small. Have you tried some games with the GTX 1080ti with the FSR option enabled? write a comment about what the change in FPS was.
