DLSS 5 Slashes FPS in S.T.A.L.K.E.R. 2 on RTX 5090 at 4K

TL;DR Summary
An early DLSS 5 build with DLAA is benchmarked in S.T.A.L.K.E.R. 2 at 4K on an RTX 5090, showing FPS drops of about 37–38% (roughly from 69–72 FPS to the mid-40s) across multiple locations, due to the neural network reconstruction; the tests use nvngx_dlss.dll from NBA 2K27 injected via ReShade, trading frame rate for cinema-like color and reduced artifacts.
