Sony Brings AI Upscaling to Base PS5 with QSSR
Sony has announced that a new AI-driven upscaling technology called Quick Spectral Super Resolution (QSSR) is now available on the standard PlayStation 5, bringing machine learning-based image enhancement to the base console for the first time. The technology, which debuted in Marvel's Wolverine and Ghost of Yōtei via recent patches, is a streamlined version of the PlayStation Spectral Super Resolution (PSSR) previously exclusive to the PS5 Pro.
According to a Sony blog post, QSSR was developed through the company's Project Amethyst collaboration with AMD and utilizes a more lightweight neural network architecture than PSSR, allowing it to run on the base PS5's less powerful GPU. While not as capable as PSSR, QSSR aims to deliver significant improvements over traditional temporal upscaling methods used on the console since its launch.
"QSSR adds more pixel-level clarity and stability to our environments," said Mike Fitzgerald, Head of Technology at Insomniac Games, in a statement. "It's a perfect companion to the launch of Marvel's Wolverine, and it brings a great taste of the PS5 Pro experience to our players on PS5." Jasmin Patry, Lead Rendering Engineer at Sucker Punch Productions, added that QSSR excels at resolving fine details "with a level of temporal stability that hasn't been possible on the PS5 console until now."
The Technical Challenge: Bringing Pro-Level Upscaling to Base Hardware
How QSSR Works Without Dedicated ML Hardware
The base PS5 lacks the dedicated machine learning silicon found in the PS5 Pro, which features 300 TOPS (trillion operations per second) of AI processing power. According to Daniel Craig, Principal Engineer for Graphics R&D at Sony Interactive Entertainment, QSSR relies primarily on FP16 math and leverages "packed math instructions" to maximize efficiency on the standard console's hardware.
"It's true that PS5 Pro was purpose built for the task," Craig told Digital Foundry. "A streamlined neural network architecture got us close but from there we leveraged a variety of less obvious hardware features to maximise efficiency." He noted that while compromises were necessary, "we didn't have to compromise as aggressively as you might think."
Digital Foundry's hands-on analysis found that QSSR delivers substantial improvements in temporal stability, detail level, and sub-pixel integrity in Marvel's Wolverine, with reduced artifacts in moving foliage. Improvements in Ghost of Yōtei were less dramatic but still noticeable, according to the publication.
PS5 Pro Shortages and Controversial Lottery System
The QSSR announcement comes as the PS5 Pro faces significant supply constraints, particularly in Japan. Sony has instituted a lottery system for Japanese customers seeking to purchase the $900 console, requiring applicants to have logged at least 60 hours of playtime on PS4 or PS5 between September 27, 2024, and September 27, 2026, using a Japan-registered Sony account.
The application window closes on October 7, with lottery winners notified around October 26 and required to complete purchases by November 2. Unclaimed consoles will be re-lotted to other eligible customers. The lottery is designed to curb scalping and ensure genuine gamers receive the hardware, though Sony has not indicated whether the system will expand to other regions.
TechSpot notes that Sony's anti-scalping measures could face complications with the upcoming launch of Grand Theft Auto VI on November 19, which is expected to drive significant console sales. If shortages persist, similar lottery systems could be implemented in the US and other markets.
Broader Implications: AI Upscaling Becomes Standard
The arrival of QSSR on the base PS5 signals a broader industry shift toward AI-driven upscaling as a fundamental part of the graphics pipeline rather than a premium feature. With the technology now available across both PlayStation 5 models, developers have a consistent target for image quality optimization.
The move also raises questions about the value proposition of the PS5 Pro. While the Pro retains significant advantages—including more generous base resolutions, higher output resolutions, and superior PSSR quality—the gap between the two consoles has narrowed. The PS5 Pro's $900 price tag, up from its original $700 launch price, may face increased scrutiny as base PS5 owners gain access to much of the Pro's visual benefits.
Industry observers will be watching closely to see whether Rockstar Games implements QSSR in Grand Theft Auto VI at launch, which could further demonstrate the technology's potential. For now, Sony appears committed to extending the current console generation's lifespan by improving the experience for all players, not just those willing to pay a premium.
