Leaked DLSS 5 halves frame rates in early tests, signaling heavy compute cost for Nvidia's neural rendering model

Modders extracted Nvidia's unreleased DLSS 5 neural rendering library from an NBA 2K27 early-access build and applied it across multiple games. Testing on an RTX 5070 Ti showed 4K performance falling from 71 to 35 fps; users report "halves" frame rates in Final Fantasy VII Rebirth. Nvidia announced DLSS 5 in March as real-time photoreal lighting and materials inference, targeting a fall release.
