DLSS 4.5 vs. FSR 4 vs. PSSR 2 Motion Aliasing and Sharpness Breakdown

Line completion, temporal stability, and edge clarity in dynamic gameplay scenes.

General by Okazaki on Mar 01, 2026

The image quality in RE Requiem on PS5 Pro is good enough for a 4K display at 60 fps. The result is in line with what the PS5 Pro was supposed to do, although not all games have matched that expectation. In a few games, the image quality has been poor. But here, the picture quality is good enough that it doesn't matter how it compares to PC upscalers. The experience with PSSR2 differs from that with PSSR1.

Initial findings indicated noise in ray tracing, prompting concerns about the recurrence of prior difficulties. After looking more closely, it was clear that the problem comes from Capcom's denoiser. When you use Capcom's denoiser instead of NVIDIA's ray reconstruction, the problem also happens on PC. NVIDIA's fix removes the noise more effectively. This behavior is not limited to PSSR2; it happens on all systems. Overall, the results are the same for everyone.

Ray Tracing Noise and How the Denoiser Works

Ray tracing noise looks the same across all upscalers when comparing PSSR2 to AMD's FSR4 and DLSS4.5. In the first sequence, reflections on the car make it seem that DLSS4.5 removes noise better at first. When the reflection is no longer blocked, the noise pattern stays the same. Capcom's denoiser for RTGI and RT reflections isn't very good at any of the options.

No matter the upscaler you choose, depth of field also adds aliasing and noise. When the depth of field is on, the picture looks lower resolution than the things around it. This is always true in scenarios where it is present, even in close-ups, when the edges of faces show raw aliasing artifacts.

Differences in Motion Handling and Aliasing

Comparisons indicate that things change based on the scene. One major problem with PSSR2 compared to FSR4 and DLSS4.5, in the L setting, is that it makes things look blurry as they move. PSSR2 shows a 1080p-like effect when you look at the armrest on Grace's chair as it moves. FSR4 and DLSS4.5, on the other hand, do a better job of preventing aliasing at edges. When at full speed, the difference shows up as momentary sparkles, but when you zoom in, it's really evident.

When a character moves, a similar pattern shows up on the rims of their spectacles. FSR4 and DLSS4.5 keep anti-aliasing consistent; PSSR2 reveals aliasing that can be seen. During motion sequences, PSSR2 shows lower line completion and edge reconstruction.

Ghosting and Stability Over Time

In some situations, PSSR2 shows greater stability over time. FSR4 introduces ghosting artifacts during the clipboard-moving sequence. These appear to be faint white trails from previous frames. PSSR2 and DLSS4.5 preset L do not show the same ghosting effect. This means that the way temporal data is stored and handled between frames differs.

We can see that PSSR2 avoids ghosting better than FSR4.

Keeping Sharpness and Detail

Overall, DLSS4.5 seems the sharpest in the intro scene. PSSR2 comes next, and FSR4 has a softer picture. DLSS4 is the best at making text on background things, such as newspaper clippings on a wall, easy to see. PSSR2 is next, and FSR4 is last.

But when the game moves to the metropolis, the comparisons of sharpness change. DLSS4.5 and FSR4 make distant details look sharper, while PSSR2 makes them look softer. DLSS4.5 and FSR4 make it easier to see where lines end by showing chain-link fences and electricity lines. Some chain links are still missing in PSSR2.

We can observe that in this comparison, sharpening controls can't be completely separated. It is still unclear whether sharpening at the platform level affects the outcome.

Final Thoughts

The way the game looks affects how people judge it. Low brightness and low contrast make it hard to see fine details and edges. When you compare two upscalers side by side, dark scenes make the differences less clear, which makes the comparison less useful. In certain lighting conditions, it is harder to see subtle differences in the reconstruction.

An overall evaluation shows that PSSR2 works like FSR4 in many ways, yet it keeps information differently over time. It doesn't ghost in certain circumstances, but it does show more aliasing and less line completion in others. DLSS4.5 is still better at sharpness and edge stability, especially in background areas with a lot of detail.
