Anti-aliasing basically renders "just-alike" pixels to fill the steps between pixels. These pixels are naturally of a lower quality but the effect is that you get a smoother jaggies free image. Supersampling/downsampling is a way of rendering the image at a higher resolution that what is supported by your display then shrinking the bigger image with more pixels to fit into your display. Basically, your 1080p (or whatever) is displaying a higher resolution image resized to fit your screen. Typically, if SSAA is done on the software side, that means that a GPU would natively render an image at a resolution higher that your displays native resolution then shrink it to fit. Very GPU intensive. What Nvidia is claiming here is a hardware approach. That wil upscale the image the GPU spits out then downsample the upscaled image and output that at yo displays native resolution. Thing is, you GPU is still only rendering a (eg) 1080p mage. And what you are output is a downsampled 4k image of an original 1080p image. Kinda silly if you ask me. It would probably be equivalent to like free FSAA and nothing more |
Wait... the GPU is not rendering in 4k? Pretty sure useless.
