NVIDIA Profile Inspector

NVIDIA Profile Inspector is a Windows tool for editing NVIDIA driver profiles through the NVIDIA Driver Settings API. It exposes the driver profile database used by the NVIDIA Control Panel, adds access to many hidden or undocumented profile settings, and makes it easy to create, adjust, export, import, and restore per-application profiles.

The tool is intended for advanced users who want precise control over game and application profiles, compatibility flags, frame-rate limiters, synchronization options, texture filtering, SLI settings, Optimus behavior, DLSS overrides, and other driver-level switches that are not always available in the standard control panel.

Highlights

• View and edit global and per-application NVIDIA driver profiles.
• Add or remove applications assigned to a profile.
• Create custom profiles for games or applications missing from the driver database.
• Search and filter profile settings quickly.
• Switch between common, known, and extended driver settings.
• Mark frequently used settings as favorites.
• Inspect and edit bitmask-style settings with the built-in Bit Editor.
• Export and import .nip profile backups.
• Export and import NVIDIA text-format profile dumps.
• Restore individual settings, whole profiles, or driver defaults.
• Use modern DLSS, DLSS Ray Reconstruction, and DLSS Frame Generation override entries where supported by the installed NVIDIA driver.
• Choose from multiple UI themes, with optional Windows 11 backdrop effects.
• Check GitHub releases from inside the app.

Download

Download the latest official build from the GitHub Releases page. Pre-release builds are available on the same page when experimental builds are published: GitHub Pre-releases.

The release archive contains the executable and the files required to run it. Extract the archive to a writable folder and start nvidiaProfileInspector.exe.

Requirements

• Windows with a compatible NVIDIA display driver installed.
• An NVIDIA GPU supported by the installed driver.
• .NET Framework 4.8.
• Administrator privileges. NVIDIA Profile Inspector must be started elevated to write changes to the NVIDIA driver profile database.

Quick Start

1. Start nvidiaProfileInspector.exe.
2. Select a profile from the profile box, or type a game or application profile name and press Enter to find the matching profile.
3. Use the search field or setting mode selector to find the setting you want to edit.
4. Change values in the settings list.
5. Click Apply Changes to write the profile changes to the NVIDIA driver database.

Before experimenting with advanced settings, export the current profile or all custom profiles so you can restore a known-good state later.

Profile Backups

NVIDIA Profile Inspector can store profile changes as .nip files. This is useful for sharing a single game profile, keeping personal presets, or backing up modified driver profiles before a driver update.

Recommended backup flow:

1. Select the profile you want to preserve.
2. Use Export for a single profile, or export all customized profiles from the export menu.
3. Keep the generated .nip file somewhere outside the driver installation folder.
4. Use Import to restore or merge profiles when needed.

Advanced Settings Notice

Many entries exposed by NVIDIA Profile Inspector are hidden, experimental, deprecated, driver-version-specific, or undocumented by NVIDIA. Values that work well for one game, driver, or GPU generation may do nothing or cause issues elsewhere.

Use profile-specific changes whenever possible, keep backups, and prefer restoring a single setting or profile before resetting the whole driver database.

Command Line

NVIDIA Profile Inspector supports a small set of startup options for imports, exports, and maintenance tasks.

nvidiaProfileInspector.exe [options] [profile1.nip] [profile2.nip ...]

Option	Description
<file>.nip	Imports one or more .nip profile files. If an instance is already running, the files are forwarded to it.
-silentImport	Imports .nip files without showing the normal success dialog.
-silent	Alias for -silentImport.
-exportCustomized	Exports all customized profiles to a timestamped .nip file next to the executable, then exits.
-createCSN	Writes the embedded CustomSettingNames.xml file to the current working directory, then exits.
-showOnlyCSN	Starts the UI with only customized settings shown.
-disableScan	Starts the UI without the initial profile scan.

Examples:

nvidiaProfileInspector.exe ".\MyProfile.nip"
nvidiaProfileInspector.exe -silentImport ".\ProfileA.nip" ".\ProfileB.nip"
nvidiaProfileInspector.exe -exportCustomized

Build From Source

The project is a WPF desktop application targeting .NET Framework 4.8.

git clone https://github.com/Orbmu2k/nvidiaProfileInspector.git
cd nvidiaProfileInspector
dotnet build .\nvidiaProfileInspector\nvidiaProfileInspector.sln -c Release

The compiled application is written to:

nvidiaProfileInspector\bin\Release\net48\

Visual Studio can also open nvidiaProfileInspector\nvidiaProfileInspector.sln directly.
