PS5 Pro's Biggest Advantage Just Came to the Base PS5, With a Catch
Sony has brought the AI upscaling that was exclusive to PS5 Pro for two years to the standard PS5 as QSSR. In reality it is a very different engineering story: reaching the same goal through a much narrower hardware path.
When the PS5 Pro launched in 2024, one of the technologies that set it apart from the standard PS5 was not simply raw power, but PSSR — PlayStation Spectral Super Resolution. The technology renders a game at a lower resolution and then uses AI to reconstruct it at a much higher one. The result is a sharper, more stable image without placing the same load on the GPU.
On October 1, Sony announced a lighter version of that technology for the standard PS5: QSSR, or Quick Spectral Super Resolution. Marvel's Wolverine and Ghost of Yōtei became the first two games to support it through updates released the same day. In Wolverine, QSSR is enabled by default.
Why wasn't it available on the standard PS5 before?
AI-based image upscaling comes with a cost: the GPU has to run an AI model for every frame. The PS5 Pro has dedicated hardware for this workload. The standard PS5 does not.
More importantly, the standard PS5 GPU does not support the same INT8 compute path used by PSSR on the PS5 Pro. These lower-precision operations can be extremely useful for running AI models efficiently. In other words, the most efficient route PSSR takes on the PS5 Pro simply is not available on the base console.
Sony therefore built QSSR around a different approach. According to the company, the technology grew out of its Project Amethyst collaboration with AMD and relies on two things: a simplified AI model and a heavily hand-tuned implementation designed to extract as much performance as possible from the PS5. Technical details Sony shared with Digital Foundry indicate that QSSR relies primarily on FP16 calculations and the console's packed-math instructions. In short, Sony did not simply move the PS5 Pro's compute path over unchanged; it reshaped the model around the hardware available in the standard PS5.
What's the cost?
There is a performance cost to squeezing the technology into the base console, and Digital Foundry's early testing gives us an idea of how large it is.
In Wolverine, when QSSR upscales from 864p to 1440p, it adds roughly 1.5 to 1.8 milliseconds of GPU time per frame. Compared with the game's own upscaler, that works out to a difference of around 8 to 10 frames per second. That may sound significant, but the gap was measured in an unlocked frame-rate test. In the game's normal 60fps performance mode, dynamic resolution comes into play: the internal resolution drops slightly to absorb QSSR's cost while the target frame rate is largely maintained. When targeting 4K, the cost rises to roughly 4.4 milliseconds per frame.
That is why Digital Foundry considers 1440p the more natural target for QSSR. While AI upscaling on PS5 Pro can aim for 4K output, the more realistic expectation on the standard PS5 is something around 1440p. Sony is not hiding that distinction either: in its own announcement, the company explicitly says PSSR remains the "gold standard" on PS5 Pro.
How big is the difference?
The results vary from game to game, and that may be the most instructive part of the story.
In Wolverine, Digital Foundry says the improvement in image quality can be remarkable. The image is more stable, fine and sub-pixel detail is reconstructed more effectively, and artefacts are reduced — particularly in moving vegetation. Insomniac technology director Mike Fitzgerald has also said the technology brings greater clarity and stability to the game's crowded streets and narrow alleyways.
In Ghost of Yōtei, however, the difference is much more modest. The reason is straightforward: the game was already using AMD's FSR 3 upscaler, and its image quality was already relatively strong. In Digital Foundry's initial testing, replacing FSR 3 with QSSR produced almost identical performance, but it did not result in a dramatic leap in image quality either.
These two examples show that AI upscaling is not a magic wand. How much it helps depends heavily on what a game was using before. With many titles still relying on older solutions such as FSR 2, those games may stand to benefit the most.
Did PS5 Pro owners lose anything?
The short answer is no — although the Pro's exclusivity has narrowed a little.
The PS5 Pro still has dedicated AI hardware, a more powerful GPU, and an upscaling target much closer to 4K. QSSR is a lightweight version of the same idea, squeezed into a far tighter compute budget. Pro owners will still get the better image, but standard PS5 owners are no longer completely left out when it comes to AI upscaling.
The more important change may be on the developer side. If a game already supports PSSR, developers can adapt that implementation to QSSR and then tune settings such as resolution separately for the standard PS5. That makes it easier to bring AI upscaling to both consoles without building two entirely separate solutions from scratch.
For now, only two games support QSSR, and Sony has not shared a broader roadmap. The technology will, however, be made available to all PlayStation developers. The direction is clear: the core idea Sony sold with the PS5 Pro — "render less, let AI fill in the rest" — is beginning to move beyond a single hardware model and become part of the wider PlayStation platform.
And the most interesting part is that Sony is doing it on a console that was never given the hardware path originally intended to make that idea work.
