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 and provides access to many hidden or undocumented profile settings that are not available in the standard control panel.
The tool solves the problem of limited access to driver-level configuration by allowing advanced users to view, edit, create, and manage per-application NVIDIA driver profiles directly. It works by interfacing with the NVIDIA Driver Settings API to read and write profile data, then presenting this information through a searchable interface organized by setting categories. Users can modify compatibility flags, frame-rate limiters, synchronization options, texture filtering, SLI settings, Optimus behavior, and DLSS overrides at the driver level, then apply changes back to the driver profile database.
NVIDIA Profile Inspector is intended for advanced users and enthusiasts who need precise control over game and application behavior at the driver level. It suits anyone managing multiple game profiles with specific performance or compatibility requirements, or those who need to configure settings unavailable in the standard NVIDIA Control Panel. The tool is particularly valuable for users wanting to preserve driver configurations across updates or share optimized profiles with others through its export and import functionality.
Development activity shows consistent maintenance with regular updates to support new NVIDIA driver features, including modern DLSS variants and frame generation overrides. The project incorporates user-facing polish through multiple UI themes and Windows 11 visual effects. The maintainer actively monitors GitHub releases and provides both stable and experimental builds, allowing users to opt into pre-release versions for early access to new functionality.
