NVIDIA’s DLSS technology probably needs no further introduction. First debuting with the NVIDIA GeForce RTX 20 series graphics cards, it harness the Tensor cores in the Turing GPUs to bring improved performance in the latest games supporting the technology. It is currently implemented in over 55 games, including the latest and greatest titles like Cyberpunk 2077, Call of Duty: Warzone, Rainbow Six Siege and more.

NVIDIA DLSS: How does it work

how nvidia dlss works

The gist of it is that NVIDIA uses an AI super resolution algorithm to achieve a higher resolution output from a lower resolution input, thus allowing for higher framerates than otherwise rendering at the higher resolution natively. NVIDIA DLSS uses four different inputs to deliver the final frame that you see:

  1. The lower resolution image rendered by the game engine
  2. The motion vectors of the same image from the game engine
  3. The high resolution output of the previous DLSS-enhanced frame
  4. A large data set of 16K ground truth images that are used to train the AI network

All of this information is used by the AI network to generate a high resolution image on a pixel-by-pixel basis, without having motion artifacts and with sharper detail and edge quality than conventional upscaling methods. NVIDIA DLSS is enabled by the massive AI performance in the latest GeForce RTX GPUs, allowing gamers to enjoy all that in real time in games.

NVIDIA DLSS vs upscaling

NVIDIA also compared DLSS against its own NVIDIA Image Sharpening, which can be used on all NVIDIA GeForce GPUs to upscale images and sharpen the result to enhance edges. Being non-AI and non-temporal, the results are often visibly less detailed than DLSS. Another example provided by NVIDIA was in Control. The game launched with DLSS that used a non-AI heuristic, before getting updated with DLSS 2.0, that harness AI. The difference is quite visible, especially in moving objects.

More games supporting DLSS are coming

DLSS games

Ever since the arrival of DLSS, newer games have been adopting the technology. However it is now being added even to older games like Rainbow Six Siege, No Man’s Sky and Rust. Part of this push might be due to an increasing number of RTX-enabled gamers out there, but also because of growing support for DLSS across game engines. The DLSS plugin for Unreal Engine 5 has just been launched, and support for Unity is also incoming.

DLSS Proton Vulkan API

Even Linux gamers won’t be missing out on DLSS, with NVIDIA working with Valve to bring DLSS to Vulkan API games on Proton. DirectX titles running via Proton will also get support for DLSS later this year.

The upcoming LEGO Builder’s Journey will also feature raytracing and DLSS, while an update for Doom Eternal will bring raytracing and DLSS to the gory shooter this 29th June. The list of games available with DLSS will continue growing, bringing enhanced performance with no loss of visual quality to more RTX-enabled gamers out there.

Pokdepinion: I still remember the times when DLSS brought disastrous visual quality in games like Battlefield V, but I am glad that those times are now behind us, with DLSS 2.0 actually bringing better graphics when enabled in the latest titles.
