The big picture: Nvidia's November 2021 update covers multiple subjects regarding what the company is doing with its image reconstruction technology. The main story is its upgraded image scaling tech, called Nvidia Image Scaling, which it's now offering as an alternative to DLSS and AMD's FSR in hopes of getting wider developer support.

There has been a lot of praise for Nvidia's DLSS -- a feature that, in games which support it, makes lower resolution images look as good or better than higher resolution images, thus enhancing performance. This works through a combination of AI, the use of information from previous frames, and the tensor cores in Nvidia's RTX graphics cards. Analyses from groups like Eurogamer's DigtialFoundry have maintained that users should always turn it on whenever available.

Comparisons between the two in games that use both have noted that FSR is simpler and in the end, less effective. Still, several big-name games as of late have opted to support FSR before adding DLSS, or indeed instead of DLSS.

Seemingly in response, Nvidia has announced it's adding more functionality to its existing image scaler. This isn't DLSS, but rather a simple upscaler similar to FSR that now has an improved sharpening algorithm with a six-tap filter, four directional scaling and adaptive sharpening filters.

Nvidia Image Scaling is activated in the Nvidia control panel under "Manage 3D settings." Once enabled, it'll add five new resolutions selectable via in-game settings menus, based on a percentage of your display's native resolution, from 85 percent down to 50 percent. Notably, the latter isn't available for 1080p monitors.

Nvidia Image Scaling even has an in-game overlay that should show the results in real-time.

Like FSR, Nvidia is making Image Scaling open-source, so it could certainly end up being supported on AMD and even Intel's upcoming graphics cards in the future.
