Launch Play
Start NV-UV-Play.exe. The .NET runtime is included. Play runs on its own and does not need MSI Afterburner.
Questions before you start?
Which graphics cards does Play support?
GeForce RTX desktop models in the RTX 20, RTX 30, RTX 40 and RTX 50 series on Windows 10 22H2 or Windows 11 (64-bit). Individual features depend on the GPU and driver.
Does Play work with a multi-GPU setup?
Do you have more than one GeForce graphics card in your PC? Yes, Play lets you select a target GPU. Under Settings → NVIDIA GPU for Play, choose the card you want Play to control. Save the selection and restart Play.
Profiles, readings and DCC Automatic use the selected card. The limitation applies to the separate DCC NVIDIA Experimental mode (Power Efficiency Mode), which currently requires a single NVIDIA GPU. The Voltage Step Scanner has the same restriction.
Selecting a GPU in Play does not change the GPU used by a game or Lossless Scaling. Full multi-GPU hardware validation is still pending.
Do I need MSI Afterburner for Play?
No. NV-UV is the companion app for MSI Afterburner. NV-UV Play is a standalone application and does not require Afterburner. Use Play separately from MSI Afterburner for GPU tuning.
Does Play cost anything?
No. NV-UV Play is free of charge.
Is Play open source?
NV-UV Play is currently not open source. Please refer to the included license notices for terms of use and further licensing questions.
What should I know about the alpha?
So far, I have personally verified Play on Blackwell (RTX 50). The community has also confirmed compatibility with Ada (RTX 40) and Ampere (RTX 30).
RTX 20 remains experimental. Multi-GPU hardware tests are still pending. New hardware writes, such as experimental voltage settings and fan control, have not been comprehensively validated.
The overlay supports desktop, windowed and borderless modes. Exclusive fullscreen has not been supported since v2.0.8.
Do I need to test profiles on my card?
The included presets are based on relatively conservative community profiles. However, instability or crashes can still occur, particularly with Performance and Max. Every GPU chip is different, and stability requirements can vary from game to game.
The Stabilizer is enabled by default when you first start Play. Please keep it enabled while getting familiar with your card’s stability. When it detects a GPU driver crash, it adjusts the affected profile step by step.
Based on experience so far, one or two corrections are often enough to reach stable settings. Some cards and games may require further adjustments, and stability in one game does not guarantee stability in every game.
After a successful Stabilizer correction, Play displays a message in the main window showing what changed.
Can Play apply my profile and stay closed afterwards?
In v2.0.10: save a profile, right-click Use as startup profile and leave normal Play Autostart off if desired. At Windows sign-in, the short startup process waits 15 seconds, applies the profile and exits. DCC and other ongoing automatic features still need Play running.
How do I skip an unstable startup profile?
Hold Shift while signing in to Windows. Automatic Play startup is skipped for that sign-in. You can then open Play manually and change the startup profile. This does not reset a curve that has already been applied.
Why can’t I save an old DCC entry as a UV profile?
The new export feature needs the curve and settings recorded during learning. Older entries may lack them. Select only the affected entry, reset it, click Apply and play again with DCC. Existing learned clocks remain usable without export.
Can UV Pilot use my own desktop profile?
UV Pilot uses Stock on the desktop by default. Choose your own desktop profile in Game override & presets. Play returns to it after the game ends. Game override remains independent.
How do I switch profiles without the main window?
Switch with Ctrl + Alt + Page Up/Down or the tray menu. Both use occupied slots 1 to 6 by default. Advanced options lets you change shortcuts and include all saved profiles.
Can the overlay use a second monitor?
Choose a display under Overlay settings → Display → Monitor. Show game readings on a second screen. If it disconnects, Play uses the primary monitor and remembers your choice.
