Inside Sony’s Upgraded PSSR Upscaler For PS5 Pro (And Why Resident Evil Requiem Is The First Showcase)

Sony is about to give PS5 Pro’s showpiece feature a serious upgrade. PSSR, or PlayStation Spectral Super Resolution, has been the console’s answer to DLSS and FSR since launch, quietly powering higher resolutions in more than 50 Pro‑enhanced titles. Now an “upgraded PSSR upscaler” is rolling out, and Resident Evil Requiem is the first game built around it.

This is more than a minor patch. Sony is effectively swapping in a new neural upscaler, refined under a project codenamed Amethyst, and tying it directly to a new system‑level toggle for PS5 Pro owners. Here is how the upgraded PSSR actually works, what’s changing compared with the launch implementation, and why Capcom’s latest horror epic is the perfect showcase.

What PSSR Is On PS5 Pro

PSSR is Sony’s AI‑driven upscaling and reconstruction solution tailored specifically for PS5 Pro’s hardware. Instead of asking a game to render every frame at native 4K, developers can render at a lower internal resolution, pass that image (plus motion and depth data) into the PSSR library, and let the AI reconstruct a sharper frame.

In practical terms, that means a PS5 Pro game might render internally at something like 1440p or 1800p, then hand things over to PSSR to generate a 4K output. PSSR analyzes the frame on a pixel‑by‑pixel basis, looking at color, contrast, motion vectors, depth, and temporal history from prior frames. The goal is to produce an image that looks closer to a higher native resolution while maintaining performance targets like 60 or even 120 frames per second.

The original PSSR already did this, and it worked well enough that dozens of launch window PS5 Pro titles adopted it. The upgraded version is Sony’s attempt to close more of the gap to high‑end PC upscalers while keeping the experience consistent and predictable on fixed console hardware.

What’s Actually New In The Upgraded PSSR

Sony describes the new PSSR as using a “substantially revised” neural network and algorithm. Internally, this comes out of Project Amethyst, a joint effort with AMD that also underpins AMD’s FSR 4 tech on PC. Where PC players get a flexible, hardware‑agnostic version in FSR 4, PS5 Pro gets a console‑tuned branch of the same ideas, with roughly six extra months of refinement targeted specifically at Sony’s machine.

At a high level, the upgraded PSSR introduces three important changes compared with the launch implementation:

First, the reconstruction quality is better at fine detail. High‑frequency information is where most upscalers struggle: the edges of thin wires, chain‑link fences, dense foliage, fine fabric patterns, or intricate facial hair. The new neural model is trained to recognize more of these patterns and retain them across frames instead of letting them shimmer, flicker, or blur away.

Second, temporal stability is improved. PSSR leans heavily on information from prior frames. When the camera moves quickly or lots of alpha effects and particles are on screen, an upscaler can introduce ghosting and smearing. The revised algorithm is better at deciding when to trust past data and when to throw it away, which reduces those motion artifacts and makes the image feel more solid during fast movement or hard cuts.

Third, the cost is tuned for PS5 Pro’s fixed hardware. Because Sony knows exactly what CPU, GPU and memory speeds every PS5 Pro runs at, it can budget how much compute the upscaler uses per frame. The Amethyst‑derived version that ships on PS5 Pro is designed so that most games can maintain their target frame rate even while feeding PSSR richer data and asking it to reconstruct from lower internal resolutions.

Developers still decide their own performance modes and resolution targets, but the upgraded PSSR effectively shifts the tradeoff curve. For the same internal resolution, you can now get a cleaner image. Or, for roughly the same image quality as before, a studio can push performance or heavy graphics features a bit harder.

How The AI Upscaling Pipeline Works On PS5 Pro

PSSR sits late in the game’s rendering pipeline, just before the final frame is sent to your display. A typical PS5 Pro frame using the upgraded PSSR goes through something like this sequence:

The game renders its internal frame at a chosen resolution. Alongside the color buffer, it also generates motion vectors, depth information, and other side data that describe how objects and pixels are moving and where they sit in 3D space.

Those buffers are then passed to the PSSR upscaler. The neural network compares the current frame to previous ones, tracks the motion of each pixel, and attempts to reconstruct where additional detail should be. Edges are carefully rebuilt to keep them sharp without excessive ringing or halos, while textures are enhanced to look more detailed at the higher output resolution.

The upgraded model uses refined heuristics for how it blends information over time. Static objects receive heavy temporal accumulation so they look especially crisp, but fast‑moving or newly revealed detail is treated more cautiously to avoid ghost trails or double‑imaging.

Once PSSR has produced the upscaled frame, post‑processing steps like film grain, chromatic aberration, and UI overlays are applied at the final resolution. That ensures the HUD and text stay razor sharp rather than being smoothed out by the upscaler.

Although Sony calls PSSR an AI upscaler, it does not require per‑game AI training. Developers use a common API, and the console ships with the trained network baked into the system software. That makes the upgrade particularly powerful, because when Sony swaps in a better model, every compatible game can potentially benefit without re‑architecting their rendering engine.

Resident Evil Requiem: The First Showcase Title

Resident Evil Requiem is the first game designed around the upgraded PSSR, and Sony is leaning on it as a flagship demo of what the tech can do. Capcom’s engineers highlight that the game’s RE Engine has been pushed especially hard in close‑up character rendering.

The protagonist’s hair and beard, for example, are rendered as individual polygon strands rather than simplified clumps. Each strand reacts to body motion and wind, and the lighting model tracks how light passes through and scatters around the hair volume. Skin materials rely on subtle normal maps and sub‑surface scattering, with tiny pores, scars, and wrinkles visible during cinematic close‑ups.

This is a nightmare scenario for a weak upscaler. If the reconstruction fumbles, hair can break into noisy flickering lines, beards can look like fuzzy blobs, and micro‑details on skin can vanish once the camera moves. According to Sony and Capcom, the upgraded PSSR preserves these details much more reliably, especially when the camera sweeps around characters or cuts quickly between angles.

Requiem’s environments also stress the tech. Dimly lit corridors, fog volumes, volumetric lighting, and dense environmental clutter create scenes rich in high‑frequency visual noise. On older reconstruction techniques, that can manifest as grainy patterns that crawl across the screen. The improved temporal stability in PSSR helps lock those details down so that the horror atmosphere feels “steady” rather than visually unstable.

Capcom’s choice to pair such a detail‑heavy presentation with a high performance target is what makes Resident Evil Requiem such a strong advertisement for the new upscaler. The studio is effectively betting that PS5 Pro’s upgraded PSSR can let them hold solid frame rates without sacrificing the unnervingly detailed close‑ups that define modern Resident Evil.

System‑Level Upgrade: Enhance PSSR Image Quality

Alongside newly built games like Requiem, the upgraded PSSR will also arrive as a system feature through a PS5 Pro firmware update scheduled for March. The key addition for players is a new setting called Enhance PSSR Image Quality.

This toggle sits in the console’s settings menu and controls whether compatible PS5 Pro titles that already use PSSR are allowed to tap into the upgraded model. Once this firmware is installed, any such game can gain sharper upscaling and better temporal stability simply by running on a PS5 Pro with the option turned on.

The important detail is that this is a system‑level change. Developers do not necessarily have to issue their own patches to benefit, although many studios are expected to do targeted updates in March to tune their render settings around the new headroom. Sony has already said that multiple existing games will be updated to explicitly adopt the upgraded PSSR over the coming weeks.

For players, that means you should expect two kinds of improvements. Some titles will just quietly look crisper once the toggle is enabled, particularly in foliage, hair, distant geometry and diagonal lines. Others will ship patches that change their performance and resolution modes, pushing higher frame rates or more aggressive graphics options because the new PSSR lets them lean harder on reconstruction.

How It Differs From The Launch PSSR In Real Games

Comparisons between the launch PSSR and the upgraded version are likely to focus on three aspects of image quality: edge clarity, fine texture detail, and temporal artifacts.

On edges, the original PSSR already handled most large objects well, but thin and diagonal lines could suffer from a soft, slightly unstable look at normal viewing distances. The upgraded algorithm appears to do a better job at reconstructing those edges without breaking into stairsteps or noisy halos, especially when camera motion is involved.

Fine texture detail should also show the upgrade. Materials like chainmail, hair, dense foliage, and embossed patterns can be partially lost at the internal resolution most games render at. By training the new network on more examples of these patterns, Sony is aiming for outputs that look closer to higher native resolutions, particularly in 4K output modes.

Temporal artifacts are where most players will feel the difference moment to moment. The launch PSSR could exhibit visible ghosting around moving characters or objects against complex backgrounds. The revised temporal logic and motion vector usage in the upgraded PSSR should cut down on these issues, making fast panning, quick turns and hectic combat sequences feel cleaner.

In effect, the new PSSR narrows the visual gap between PS5 Pro’s reconstructed 4K and a hypothetical native 4K image, while leaving developers more budget to spend on lighting, effects and simulation.

What This Means For Future Pro‑Enhanced Games

For upcoming PS5 Pro titles and patches, the upgraded PSSR changes how studios can approach the classic resolution versus performance tradeoff.

Developers who want a rock solid 60 frames per second now have a stronger safety net. They can choose a lower internal resolution than they might have dared with the original PSSR, spend more GPU time on dynamic lighting, complex shaders or heavier particle effects, and trust that the upscaler will reconstruct a convincing 4K output.

Studios chasing 120 Hz modes gain similar flexibility. Hitting 120 frames per second while pushing modern visuals is notoriously difficult on console. With the improved PSSR, more games may be willing to offer 120 Hz performance modes while still presenting a sharp enough image to satisfy players on large 4K TVs.

Visual showpieces benefit too. Single‑player cinematic games can afford to crank up per‑pixel effects, ray‑traced features and rich animation systems, leaning on PSSR to hold perceived image quality together when the GPU is pushed toward its limits.

Because PSSR is a standardized library that ships with the console, developers also get predictability. Sony’s engineers handle the heavy lifting on the reconstruction algorithm and neural model, and studios integrate through a stable API rather than writing their own bespoke upscalers. When Sony rolls out this upgraded model, every future Pro‑enhanced build that opts in can ride those improvements.

The Bigger Picture For PS5 Pro

The arrival of the upgraded PSSR upscaler cements PS5 Pro’s position as a machine designed around sophisticated reconstruction rather than brute‑force native resolution. That aligns it more closely with how PC GPUs and high‑end TVs already work, where scaling and AI‑assisted processing are key to making modern visuals playable at high frame rates.

Resident Evil Requiem is the first proof of concept, but March’s wave of patches and Pro‑enhanced titles will be the real test. If Sony’s claims about finer detail retention and improved stability hold up across a broad set of games, PSSR will move from a quiet background feature to one of the defining reasons to seek out PS5 Pro versions of multiplatform releases.

For now, PS5 Pro owners should keep an eye out for the firmware update, flip on Enhance PSSR Image Quality when it appears, and watch closely as Resident Evil Requiem stalks its way through dark corridors of Capcom’s latest RE Engine showcase. The terrors you see on screen might be the sharpest yet on a PlayStation console.
