It’s a big news day for Nvidia as the company has unleashed a barrage of updated software, including some free tools that could prove quite useful to a lot of people. At the top of the list is an updated version of DLSS (Deep Learning Super Sampling), followed by the news that its Nvidia Image Scaling (NIS) technology will be open source so it can work with any GPU, and lastly , but not at least it is launching ICAT, which stands for Image Comparison and Analysis Tool. Let’s dive in.

Nvidia DLSS has been updated to version 2.3, which according to Nvidia, “… makes even more intelligent use of motion vectors to improve the details of moving objects, particle reconstruction, ghost images and temporal stability.” The following games will include support for the latest version of DLSS:

  • Baldur’s Gate 3
  • Bright memory: infinite
  • Cyberpunk 2077 (adding DLSS 2.3 support on Nov 16)
  • Crysis 2 Remastered
  • Crysis 3 Remastered
  • Deathloop
  • Eternal DOOM
  • Farming Simulator 22 (Released Nov 22 with DLSS 2.3 support)
  • Grand Theft Auto: The Trilogy – The Definitive Edition
    • Grand Theft Auto 3 Definitive Edition
    • Definitive Edition of Grand Theft Auto Vice City
    • Definitive Edition of Grand Theft Auto San Andreas
  • Jurassic World Evolution 2
  • Marvel Guardians of the Galaxy
  • Rise of the Tomb Raider
  • Shadow of the Tomb Raider
  • Sword and fairy 7

Additionally, 10 new games are receiving DLSS support, including the recently released Battlefield 2042 and Grand Theft Auto: The Trilogy.

Moving on to what is arguably the biggest news, Nvidia has updated its Image Scaling technology and will make it open source in the future to compete with AMD’s FidelityFX Super Resolution (FSR). This means that in theory it could work with any GPU, and the SDK is available on Github. The big changes for Nvidia card owners is that there will now be a slider that you can adjust via GeForce Experience, including the option to make game changes via overlay. Pressing Alt-F3 in the game will allow you to see the adjustments you make in real time. Alternatively, you can change the scaling settings globally or per game in the Nvidia Control Panel.

The newest GeForce driver lets you customize image scaling per game or globally.

Nvidia says its updated scaling technology has, “… a new algorithm that uses a 6-touch filter with 4-directional scaling and adaptive sharpening filters to improve performance. It sharpens and scales in one pass so it’s very efficient. “Nvidia also included a comparison of various enhancement technologies for the Hired Gun game displaying 4K, 4K FSR, 4K NIS, and with DLSS.

Scaling technology compared to an RTX 3060, AMD 59590X and 32GB of RAM.

Finally, Nvidia is releasing ICAT for pixel screenshots to compare image quality, which can download here. According to Nvidia, “ICAT allows anyone to easily compare up to 4 screenshots or videos with sliders, side-by-side zooming, and peeking pixels. Align the comparisons spatially and temporally, examine the differences, and draw your conclusions. “

Editor’s note: I have spent some time with ICAT since Nvidia announced the program. It is a tool for making simple A / B comparisons between two different versions of an image or video. There is a useful online service called imgsli which allows you to upload two different versions of the same image for easy comparison with a slider. ICAT is a more sophisticated version of the same concept with the ability to handle video, not just images. –JH

All of these new technologies are available today, either through the Nvidia website or with the updated GeForce driver, version 496.76. New image scaling features are available through GeForce Experience version 3.24.0.114.
