ComputerBase’s latest blind test pits NVIDIA’s DL SS 4.5 against AMD’s upgraded FSR 4.1 across seven titles, from *Pax Romana* to *The Last of Us Part I*. In six games, DL SS 4.5 wins on sharpness and frame consistency, while FSR 4.1 edges out only in *Resident Evil Requiem*.

Earlier the company released a similar comparison with FSR 4.0, showing a clear improvement to 4.1, yet still trailing DL SS 4.5. The blind methodology—labelled videos without revealing rendering technique—ensured unbiased community voting, and aggregate user sentiment to validate performance claims, and maintain transparency for all participants.

DL SS 4.5 delivers sharper details and smoother frame generation, making it the preferred choice for consumers who prioritize image quality. AMD’s progress suggests future FSR releases could narrow the gap, but current data confirm NVIDIA’s technology remains the benchmark for next‑generation upscaling in mainstream gaming.

With consumers increasingly favoring DL SS 4.5 outputs over native rendering, the competitive race pushes both vendors toward higher fidelity. As neural rendering techniques mature, the industry will likely see a new standard where choice of upscaler defines performance, underscoring the importance of continuous innovation in GPU‑driven graphics.
