NVIDIA DLSS 4.5 outperformed AMD FSR 4.1 in a "blind" test

NVIDIA DLSS 4.5 Surpasses AMD FSR 4.1 in "Blind" Testing

The scaling-tech skirmish got a new chapter. In a fairly large "blind" test run by experts, people were shown images from seven popular blockbuster games and asked to say which looked better without being told which algorithm did the work. The result was pretty one-sided: DLSS 4.5 came out on top in six of the seven titles, at least according to the voters (pro reviewers and regular players mixed together, i.e., a diverse pool).

One outlier: Resident Evil Requiem. There, FSR 4.1 edged past DLSS 4.5 — not a mysterious fluke, but tied to how ray tracing and reconstruction are handled. DLSS 4.5 isn’t available with RT in that title because there’s no suitable ray-reconstruction model for the upscaler; FSR 4.1 doesn’t suffer the same RR↔upscaler compatibility issue. Still, the "red" RR option exists in only two games, so this advantage is limited in scope (and a reminder that results can hinge on title-specific tech, e.g., engine support and available models).
