QSSR is coming to the standard PlayStation 5. In a PlayStation Blog post, Sony introduced Quick Spectral Super Resolution, a lighter performance tier of PSSR, until now exclusive to PS5 Pro. Marvel's Wolverine and Ghost of Yōtei are the first games to receive it, through a free update on the base console.
The announcement is separate from the Echoes of Sekigahara DLC. QSSR is a new graphics library, born from Project Amethyst, Sony's AI graphics collaboration with AMD.
What changes on base PS5
PSSR analyzes an image pixel by pixel and reconstructs the frame with more detail and stability than conventional upscaling. Sony says the compute cost had made that experience impossible on PS5. QSSR works around that with a streamlined neural network and a hand-tuned implementation for the original console.
The official post keeps the hierarchy clear. PSSR remains the gold standard on PS5 Pro. QSSR improves detail and temporal stability on PS5. Mike Fitzgerald, head of technology at Insomniac, described clearer streets in Madripoor and Shinjuku in Wolverine, and a taste of the Pro experience. Jasmin Patry, lead rendering engineer at Sucker Punch, said the temporal stability in Ghost of Yōtei on PS5 had not been possible until now.
Why it is not the Pro chip
Digital Foundry spoke with Daniel Craig, principal graphics R&D engineer at SIE. PS5 Pro has 300 TOPS of dedicated hardware and uses INT8 instructions, close to AMD's FSR 4 path. The base PS5 lacks that block. QSSR relies primarily on FP16 math.
In DF's test, QSSR was about 1.5 ms to 1.8 ms slower than Insomniac's own upscaler when scaling from 864p to 1440p, roughly 8 to 10 frames per second in that fixed comparison. In a 60 Hz performance mode, dynamic resolution targets 60 fps: internal resolution drops to make room for QSSR, the frame rate stays similar, and the image is cleaner, with less shimmer and better fine-detail integrity. DF also notes the gap with Pro remains.
What comes next
The library is available to other PlayStation studios. Digital Foundry notes that games already using PSSR can add QSSR with relatively little work, almost as a settings swap, while titles without PSSR need more retrofit. Sony did not publish a list of upcoming games. There is no system-wide toggle: each game must be updated.
