Quick Report

NVIDIA App 11.0.9 adds DLSS 4.5 Ray Reconstruction support and a new per-game Resizable BAR toggle for supported GeForce systems. The app update makes it easier to spot DLSS 4.5-related features and manage the PCIe resize setting without hunting through more fragmented driver controls.

The practical value is modest but meaningful: RTX owners gain finer control over Resizable BAR on a per-game basis, while DLSS 4.5 Ray Reconstruction becomes more visible and easier to verify in the NVIDIA app. That makes the update feel like a user-focused polish pass rather than a major platform shift, but it still matters for people tuning a supported rig for games that benefit from modern upscaling and ray-traced lighting.
