Why is DLSS or other upscaling technology essentially required to get high framerates now days?
In: Technology
You only need to do upscaling when you’re running at higher resolutions. Modern GPUs will easily get high frame rates at 1080p, but as they start having to push higher native resolutions, the computational demands increase greatly. 4K resolution has 4x the pixels as 1080p, and thus needs a corresponding increase in computational power to render it. You’ll usually have higher resolution textures that require much more memory to store as well. It’s not entirely a linear 4x increase, since some of the rendering stages aren’t done in the pixel space.
DLSS lets you render at 1080p, then it uses a much more computationally efficient algorithm to upscale it to 4K. It’s not quite as visually perfect as true native rendering resolution, but it’s good enough for most people to not notice or care at all.
