What Is PSSR for PS5 Pro? | Push Square

Sony is debuting a new technology with the PS5 Pro called PlayStation Spectral Super Resolution, or PSSR for short.

While the buzzword may sound exciting, you may be scratching your head wondering what PSSR is and why it matters. We’re going to dig into all of those details on this page as part of our PS5 guide.

PSSR is a proprietary AI-based upscaler, similar to NVidia’s Deep Learning Super Sampling, or DLSS. Its introduction is significant, because it’s the first time technology of this type has existed on consoles.

Sony has described PSSR as one of the three reasons to upgrade to the PS5 Pro. In its announcement presentation, it listed the AI-based upscaler alongside a larger GPU and advanced ray tracing as one of the console’s flagship features.

In layman’s terms, AI-based upscaling analyses the image on screen and improves the resolution using machine learning. This means that PSSR is able to take a lower resolution image and reproduce it at a higher resolution, making it seem clearer than it actually is.

A good way to think of it is like putting on a pair of spectacles. The pictures you see without your glasses may be blurred or imprecise; putting on your glasses makes them sharp and clear. PSSR uses AI-based upscaling to produce similar results.

Is PS5 Pro more powerful than PS5?

PSSR produces higher resolution pictures from lower resolution sources. This reduces the computational overhead associated with rendering games at higher resolutions, because developers can target lower resolutions and still achieve a similar level of image quality.

In simpler terms, this means developers can point the PS5’s power at other areas of importance, like lighting and ray tracing. A lower resolution image with all of these features enabled can then use PSSR to achieve a clean 4K picture.

Because PSSR is AI-based, it can be trained on the games you play, so its ability to upscale will improve significantly over time. That means the
