A few new features and improvements. The headline one started with Forza Horizon: browsing community tuning setups for cars, it struck me that undervolting deserves the same thing :) A shared place to look up what values people actually run. That became UV⚡Try. On top of that: configurable Smart Hz, global tier overrides, scanner improvements, and a fix for the game-switch bug.
UV⚡Try Community UV Database
A new button next to the presets opens a browsable list of community undervolt values for your card, grouped into Eco / Balanced / UV+OC, with confidence labels and source links. Right-click an entry to apply it to a profile slot.
This rolls out in phases:
- Phase 1 (this build): Browse the database and apply values. You can rate entries with stars for yourself (local only) to remember what worked on your card.
- Phase 2 (next): Community ratings, so you can see which values actually hold up across many users.
- Phase 3 (later): Upload and share your own UV settings with everyone.
As always: community values are a starting point only. Every card is different (silicon lottery), so verify on your own card.
Global Override & No Override (Game Library)
Set one global tier that applies to every running game, and flag individual games as "No Override" to exempt them. Handy for UV-Pilot-only setups.
Smart Hz is now configurable
Right-click the Smart Hz button to choose your desktop idle refresh rate from the rates your monitor actually supports. Picking a rate activates Smart Hz right away.
Thanks @SammySamer and Paikuuhan (Discord) for both suggestions
🐛 Fixes & Improvements
- Voltage Step Scanner. The stress engine received a rework: it now validates more frames while the GPU is under load, and the stress profiles for smaller cards were retuned. This is an ongoing area and feedback from testing is welcome. As always, a manual stability pass on top is recommended.
- UV-Pilot game-switch fix. Games that restart themselves (for example during an in-game update) no longer trigger a false "game exited" and fall back to the wrong profile. A short grace period keeps the profile alive until the game's process reappears. Also helps other multi-process titles.
- Blackwell voltage floor hint. At about 875 mV and below, the Blackwell driver does not hold the V-Lock and boosts back up, so the undervolt does not stick. NV-UV now shows an inline hint in the V-Lock tab. For a stable lock on RTX 50, choose above 875 mV. This is driver behavior, not something the tool can override.
🎮 Game Database
- Updated to the latest version (run a database check in NV-UV to pull it).
- Chrome removed from the database (it kept triggering UV-Pilot unintentionally). It can be re-added manually as a user entry if wanted.
- Wuthering Waves marked ambiguous (uses window-title verification now).
- Added Gothic 1 Remake and 1666 Amsterdam.
🧪 Ampere (RTX 30)
Ampere support should work and has been verified on several models. It is still newer than the Blackwell and Ada paths, so further input is very welcome. If something looks off, please attach a log.

try NV-UV Play
Want to just start and play without setting up Afterburner first? Check out NV-UV Play. It works directly through NVAPI with no Afterburner dependency, ships with a curated four-tier preset system (Eco, Balanced, Performance, Max plus an MFG tier for Blackwell), and gets you tuning in minutes. Same game library as NV-UV, just a faster way in.
