Free open-source tool to access hidden NVIDIA driver settings, customize per-game profiles, and unlock advanced GPU rendering options not exposed in the NVIDIA Control Panel. Created by Orbmu2k. Latest version 3.0.1.12.
⬇ Download NVIDIA Profile InspectorNVIDIA Profile Inspector (NPI) is a free, open-source Windows utility that exposes hidden settings in the NVIDIA graphics driver. It lets you customize per-game profiles with options the official NVIDIA Control Panel doesn't show — anti-aliasing overrides, ambient occlusion compatibility flags, frame rate limits, V-Sync behavior, and dozens of advanced rendering options that NVIDIA includes in their driver but doesn't expose to end users.
Created and maintained by developer Orbmu2k since around 2010, NVIDIA Profile Inspector has become the standard tool for PC gamers, modders, and graphics enthusiasts who want fine-grained control over how specific games render. The tool reads its database from your installed NVIDIA driver, so newer features become available as drivers update.
These are two different tools, often confused because they share an author and similar names:
| Feature | NVIDIA Inspector (legacy) | NVIDIA Profile Inspector (current) |
|---|---|---|
| Author | Orbmu2k | Orbmu2k |
| Status | Discontinued | Actively maintained |
| GPU monitoring | Yes | No |
| Overclocking | Yes | No |
| Driver profile editing | Yes (basic) | Yes (full) |
| Recommended for | Legacy systems only | All current users |
| For overclocking, use instead | — | MSI Afterburner |
If you're searching for "nvidia inspector" or "inspector nvidia" — you almost certainly want NVIDIA Profile Inspector (NPI). The original NVIDIA Inspector hasn't received updates and lacks support for modern GPUs and rendering features. NPI is its actively-maintained successor for the profile-editing functionality.
Edit driver settings per-game. Settings apply only when the specified game is running.
Force MSAA, SGSSAA, FXAA, or DLAA on games that don't natively support them.
Force 16x AF on textures, override game settings, override driver default behavior.
Enable HBAO+ in games without native support using compatibility bits database.
Set per-game FPS caps to reduce GPU load, save power, or eliminate screen tearing.
Configure V-Sync, adaptive sync, fast sync, and triple buffering per game.
Customize Dynamic Super Resolution and Deep Learning DSR factors and smoothness.
Apply game-specific compatibility flags from the community database to fix rendering issues.
Backup and share profile configurations. Import community-created profile packs.
Configure SLI behavior and predefined profiles per game (limited use on RTX cards).
No installation required. Single executable runs from any folder. Easy to update.
Source code on GitHub (Orbmu2k/nvidiaProfileInspector). Free forever, no ads.

NPI needs admin rights to write driver profile changes.Antialiasing - Mode to Override any application settingAntialiasing - Setting to your desired AA level (e.g., 4x [4x Multisampling])Antialiasing - Transparency Supersampling to 4x Sparse Grid Supersampling| Operating System | Windows 7, 8, 10, 11 (32-bit or 64-bit) |

Older games often shipped without modern anti-aliasing options. NPI lets you force SGSSAA (Sparse Grid Supersampling) on games from the 2000s and early 2010s, dramatically improving image quality. Combine with anisotropic filtering forced to 16x for sharper textures.
Some games have rendering bugs that compatibility bits can fix. The community maintains lists of known compatibility bits for various games. Apply them via NPI to resolve issues like flickering shadows, broken effects, or AA not working.
Many games don't include ambient occlusion options or use weaker forms. NPI's compatibility bits database includes profiles for forcing HBAO+ in dozens of games that lack native AO support.
Limiting frame rates per-game saves power, reduces GPU temperature, and can eliminate screen tearing. Useful for older games where unlimited FPS produces 500+ FPS and unnecessary GPU load. NPI's frame rate limiter is more reliable than in-game limiters in many cases.
Configure adaptive sync, fast sync, or traditional V-Sync per game. Solves problems like high input lag in some games while preserving smooth gameplay in others.
NVIDIA's Deep Learning Dynamic Super Resolution (DLDSR) lets you render at higher-than-native resolution and downsample for sharper image quality. NPI exposes additional DSR factors and smoothness controls beyond what the NVIDIA Control Panel shows.
Use File → Export profiles to save your current profile configuration before making significant changes. This lets you restore your previous state if a change breaks something. Backup files are small (.nip format) and load instantly.
If a game starts behaving badly after profile changes, reset just that game's profile (Profile dropdown → Reset to default) rather than resetting all profiles. The "Restore defaults" button affects only the currently selected profile.
NPI doesn't auto-save. If you make changes and close the application without clicking "Apply changes" (the green checkmark), your modifications are lost. Get in the habit of applying after each change.
When applying compatibility bits from the community, use trusted sources like the PCGamingWiki or established forums (Guru3D, NeoGAF). Random forum posts may contain errors that cause stability issues.
NVIDIA sometimes adds default profiles for new games via driver updates. After major driver updates, your custom changes might be reset for newly-officialized profiles. Re-apply your settings if needed.
NPI's popularity has spawned numerous mirror sites — some legitimate, some bundled with adware. Use these official or trusted sources:
| Tool | Function | Best For |
|---|---|---|
| NVIDIA Profile Inspector | Driver profile editing | Per-game settings, AA forcing, compatibility bits |
| NVIDIA Control Panel | Standard driver settings | Basic settings most users need |
| NVIDIA App / GeForce Experience | Driver updates, game optimization | Casual users, automatic settings |
| MSI Afterburner | Overclocking, monitoring | GPU overclocking and tuning |
| RivaTuner Statistics Server | Frame limiting, OSD | FPS limiting and overlay statistics |
| Nvidia Inspector (legacy) | Old combined tool | Not recommended — outdated |
Most enthusiasts use NPI alongside MSI Afterburner — NPI for driver profile editing, Afterburner for overclocking and monitoring. They complement rather than compete with each other.
Run NPI as administrator. Right-click the .exe and select "Run as administrator." UAC must be allowed to write to the driver profile database.
Verify the game is using the profile you edited (not "Global Settings" or a different profile). Some games detect their profiles by exe name — make sure the profile matches your installed game's launcher.
Compatibility bits force features that may not work in all games. Reset the profile (Profile → Restore defaults) to undo. Then research correct compatibility bits for your specific game version.
Some settings are only available with specific GPU generations or driver versions. Updating your NVIDIA driver to the latest may expose more options. Older GPUs (Maxwell, Pascal) may not support all settings RTX cards do.
Use the search box at top of the profile dropdown. If still missing, you can create a new profile via Profile → Create new profile, then add the game's executable name in the executables list.
NVIDIA Profile Inspector (NPI) is a free open-source utility that lets you access and modify hidden settings in NVIDIA's graphics driver. It exposes advanced rendering options and per-game profile settings the standard NVIDIA Control Panel doesn't show.
NVIDIA Inspector was an older combined tool with overclocking and monitoring features. NVIDIA Profile Inspector is the current focused successor — it kept the profile-editing functionality. For overclocking now, use MSI Afterburner.
Yes. NPI is open-source on GitHub and has been trusted by the PC gaming community for over a decade. It only modifies driver profile settings, not Windows system files or hardware. Download from official sources to avoid versions bundled with adware.
Yes, completely free and open-source. No premium tiers, trial limits, or advertisements. Be cautious of websites charging for the tool — these are typically just rehosted free versions with bundled software.
Customize hidden NVIDIA driver settings: anti-aliasing modes, anisotropic filtering, ambient occlusion compatibility, frame rate limits, V-Sync behavior, texture filtering, SLI profiles, DSR/DLDSR settings, and per-game compatibility bits.
NPI works with any NVIDIA GPU using current drivers — GeForce GT/GTX/RTX from Fermi generation through current RTX 40-series. It does not work with AMD or Intel graphics cards.
Yes, NPI requires administrator privileges to write changes to the NVIDIA driver profile database. The application is portable, but profile changes themselves require admin access.
No. NPI only modifies driver software settings, not hardware. It cannot overclock, change voltages, or adjust fan curves. Worst case is a graphical glitch or game crash, both easily fixed by reverting changes.
