As per the previous comment - this is a sharpening filter, it just needs shaders which are plentyful on cards going back many years. There are third-party and nVidia equivalents. You might be confusing it with DLSS, which is an upscaler - ie renders at a lower resolution and then upscales the final 2d image. Upscaling often does use sharpening to help mask the loss of detail.
