Sony’s introduction of QSSR (Quick Spectral Super Resolution) brings a scaled-down, highly optimized version of the PS5 Pro’s PSSR AI upscaling technology directly to the base PlayStation 5 model.
Here is a breakdown of what QSSR is, how it works, and what it means for standard PS5 owners:
1. What is QSSR?
QSSR is a new performance tier of machine-learning-based image upscaling developed as part of Project Amethyst (Sony’s ongoing graphics collaboration with AMD). Because the standard PS5 lacks the dedicated machine-learning hardware and raw silicon power of the PS5 Pro, Sony engineered QSSR specifically for the base console’s constraints using:
-
A Streamlined Neural Network Architecture: Reduced in size and complexity to minimize computational overhead.
-
Hand-Tuned Implementation: Tailored to make the most of the base console’s GPU capabilities (relying heavily on FP16 formatting and packed math instructions).
2. How Does It Impact Gameplay?
-
Sharper Details & Stability: QSSR analyzes game frames pixel by pixel, dramatically reducing shimmering, ghosting, and image breakup (flickering) during movement—particularly on fine details like hair, foliage, distant structures, and complex geometry.
-
Target Resolution: While the Pro’s PSSR easily handles native 4K targets, QSSR on the base console is most effective when targeting presentation resolutions closer to 1440p in 60 fps modes, balancing performance with clarity.
-
Not System-Wide: It is an opt-in graphics setting provided within supported games rather than an automatic system-wide upgrade. Because running neural networks incurs a performance/frame-time cost, developers and players must balance it against raw frame rate targets depending on the graphics mode.
3. Which Games Support It?
Sony has rolled out QSSR via patches for two major titles:
-
Marvel’s Wolverine
-
Ghost of Yōtei
Moving forward, Sony plans to make QSSR broadly available to third-party and first-party developers alike, allowing them to squeeze higher fidelity out of the aging base hardware without requiring users to purchase a PS5 Pro.
