Sony slims its PS5 Pro AI upscaler to run on the base PS5

A base PS5 owner who installs the latest Ghost of Yotei patch finds one new entry among the graphics options ^[6]. It is QSSR, a lighter version of the PSSR upscaler that arrived almost two years ago as a headline feature of the PS5 Pro ^[16]. Sony calls it a "new performance tier of AI upscaling," built through Project Amethyst, its graphics work with AMD ^[1].

The hardware gap that once led Sony to call this "impossible" is still there ^[8]. Digital Foundry found QSSR slower than PSSR because the base console has no dedicated machine-learning silicon, and expects results closer to an upscaled 1440p ^[3]. Sony got around the gap with a smaller network, hand-tuned to the older chip ^[2].

Sony is pitching Pro-style image quality on the cheaper console. So far it has shipped an optional setting in two games from its own first-party studios ^[6][9]. "While PSSR remains the gold standard on PS5 Pro, QSSR provides some notable improvements to both image detail and image stability on PS5," Daniel Craig, PlayStation's principal engineer of graphics R&D, wrote ^[10]. Insomniac says Wolverine gets clearer pixels in dense areas such as Madripoor and Shinjuku ^[12]. Sucker Punch says Ghost of Yotei's image is steadier than the PS5 managed before ^[13]. Gizmodo watched Sony's comparison videos and thought the difference might be hard to spot from across the room ^[14].

Studios are the first audience. Craig told Digital Foundry that QSSR is "fundamentally a drop-in replacement for titles that already support PSSR," and that it needs only a few days of tuning ^[11]. Sony says it will offer QSSR to all PlayStation developers ^[7]. The older console needs more of that tuning. "On PS5 Pro, developers almost uniformly output to 4K and adjust render resolution beneath it," Craig said ^[4]. "On PS5, teams have to be more flexible, tuning not just render resolution, but also their intermediate and final presentation targets depending on the graphics mode," he said ^[5].

Reach depends on adoption. The coverage includes no install base and no count of players who switch the option on, so for now QSSR reaches the base PS5 owners of two games ^[6]. Digital Foundry still wrote that "low resolution and poor upscaling have impacted so many titles in this generation, but QSSR could make a big difference" ^[19].

For buyers, the Pro costs $900 and the base PS5 without a disc drive costs $600 after the 2026 price rises ^[15]. In a game that ships both tiers, the $300 difference buys the step from roughly 1440p output to 4K ^[17][18].

For a studio lead, two facts sort the decision. One is whether the title already ships PSSR on Pro. The other is whether its base PS5 version suffers from the low resolution Digital Foundry describes ^[19]. If both are true, adding QSSR is the clear call: Craig's few days of tuning, plus a pass on the presentation targets for each graphics mode ^[11][5]. A PSSR title whose base version already looks sharp can add it cheaply, but the gain is one Gizmodo found hard to see from across the room ^[14]. A title without PSSR is outside Craig's estimate ^[11]. If its base version is blurry, the studio should get the work scoped with Sony first. If it looks fine, QSSR can wait.
