Nvidia has announced official support for DLSS 5 on older RTX 40-series graphics cards, reversing its initial plan to restrict the technology to newer RTX 50-series hardware. The decision comes after independent modders successfully adapted DLSS 5 to run on a wider range of GPUs, effectively expanding access beyond Nvidia's original scope.

Early performance testing, however, has surfaced a troubling contradiction. In NBA 2K27, enabling DLSS 5 on an RTX 5080 system resulted in frame rate reductions as high as 73%, directly undermining the feature's core promise of improving gaming performance. The finding raises questions about whether the technology's benefits justify the computational costs in certain titles.
