XeSS a “Deuxième génération” Technologie de mise à l'échelle au pair avec DLSS 2.0 et FSR 2.0: Fonderie numérique
An upscaling algorithm by design adds to frame-times (time taken to render a frame to display), and in Digital Foundry’s testing, the most aggressive preset of XeSS, Performance, which upscales 720p to 1440p, adds 2 ms to the frame-time. A 1080p to 4K upscaling in the same mode, adds 3.4 ms to the frame-time, which jumps from 8.8 ms to 12.2 Mme (une augmentation de 3.4 Mme). The increase in frame-times is a good trade-off when you consider the performance gained—a staggering 88 percent increase in frame-rates for 1080p to 4K upscaling, et 52 percent increase with 720p to 1440p upscaling. Frame-times increase as you move up the presets toward the Quality mode, which renders the game at resolutions closer to native-resolution, so the performance-gained is smaller. XeSS offers a preset it calls “Ultra Quality,” which renders the game at a resolution closest to native, while still yielding a 16-23 percent frame-rate gain, with an output that’s practically indistinguishable from native-resolution.
