This release improves first-launch profile protection, Blackwell profile detection, Hotspot maintenance, startup reliability and several user-facing workflows.

For a manual installation, download only NV-UV-v0.99.5.5-Portable.zip
Improvements
- Protection of existing Afterburner profiles during first launch has been improved. NV-UV captures the stock curve without changing an already active manual V/F curve or occupied profile slots.
- Detection of manually sharpened Blackwell profiles in the low-voltage range has been improved. Previously, their effective clock could be detected incorrectly.
- Working Hotspot installations remain unchanged. Older NV-UV-managed setups are updated to MSI Afterburner's compatible native GPUProbe path only when required, with automatic backup and rollback protection.
- “Fix NV-Overlay” provides a direct repair for NVIDIA Overlay no longer appearing in games and may avoid reinstalling NVIDIA App or the graphics driver.
- Interface scaling now also offers 80% and 90%. NVIDIA's efficiency feature is named “NVIDIA Power Efficiency Mode”, and several help and form labels have been clarified.
- Game Database 2.18 contains 652 games and adds an Eco preset for Halo: The Master Chief Collection.
Fixes
- A configuration profile temporarily locked by MSI Afterburner no longer leaves NV-UV stuck on “Initializing…”. NV-UV briefly retries the read and continues starting safely if the file remains busy.
- Pending Game Replay downsteps are stored more reliably and are only cleared after the profile update succeeds.
