Other than through the latest version of DLSS, NVIDIA is pushing image quality tools and technologies even further today with the release of ICAT, a comparison tool, and with the updated NVIDIA Image Scaling upscaling technology.

Let's start with the latter. Image Scaling originally launched a couple of years ago as an option available through both the Control Panel and the GeForce Experience software. However, today's new Game Ready driver (version 496.76, optimized for Battlefield 2042) includes a significant improvement to the spatial upscaling algorithm, which now uses a 6-tap filter with 4 directional scaling and adaptive sharpening filters to boost performance. According to NVIDIA, it sharpens and upscales in a single pass, making it 'very efficient' compared to existing algorithms (no doubt a jab to AMD's FSR).
