Basics
What is NVIDIA Profile Inspector?
A free, open-source Windows program that edits the per-game profiles inside the NVIDIA driver, including settings the NVIDIA App does not show. It is not running when you play.
Is it made by NVIDIA?
No. Orbmu2k created it and it is published under the MIT licence. This site is independent too, and not the official project page.
How is it different from the NVIDIA App?
Both edit the same driver profile database. NPI reaches every game and many more settings, and it can export and import profiles as .nip files. The App is simpler.
The Control Panel is gone from my PC, what now?
NVIDIA announced with driver 610.47 that the classic Control Panel is retiring for GeForce. The settings still exist in the driver, and NPI writes the same profile database.
Does it work on AMD or Intel GPUs?
No. It talks to NVIDIA's driver only, and on a PC without one it shows a single error and does nothing else. LAB

Does it work on Windows 11 and Windows 10?
It needs a supported Windows version with .NET Framework 4.8 and an NVIDIA driver. The requirements page lists what we confirmed.
Do I need to install it?
No. You unzip it to a writable folder and run it as administrator.
What is the difference between NVIDIA Inspector and NVIDIA Profile Inspector?
They started as one program. The profile editor was split out in March 2016, and the original kept the monitoring and overclocking parts.
What is NVPI Revamped and should I use it?
A community fork with its own interface and documentation. We could only check that it starts, so we cannot rank it.

Is there a 3.5.0.0 version?
Not officially. That number belongs to an older fork that some download portals list. The official versions are 3.0.2.1 stable and 3.0.2.3 pre-release.

Safety
Is it safe?
It is open source, and Defender and ClamAV found no threats in the releases we scanned. It is not code-signed, so download it only from its GitHub page. LAB
Why does my antivirus or SmartScreen warn about it?
The file is not code-signed, so SmartScreen may warn on first run. Compare its SHA-256 with the known list before you run it. LAB
How do I know my download is the real one?
Hash the zip and compare it with the release hashes we recorded from GitHub. The download page has a verifier that does it in your browser. LAB
Can it get me banned?
No vendor has said it is safe or unsafe. The one documented NPI-related ban wave is Crytek's in Hunt: Showdown, for visibility advantages. Keep to non-visual settings online. OFFICIAL
Can it damage my GPU?
It edits driver profile values, not clocks or voltages. A bad value can still cause crashes, so back up first and change one thing at a time.
Why does it need administrator rights?
Its manifest requests them so it can write to the driver's profile database. LAB
Using it
How do I use it for the first time?
Open it as administrator, pick a profile, change one value, click Apply Changes and restart the game. The tour walks through each step.
Do changes apply automatically when the game starts?
The driver reads the profile when the game starts, so restart the game after you apply a change.
Do I have to click Apply every time?
Yes. Nothing is written to the driver until you click Apply Changes.
Why does my game ignore a setting I changed in Global?
A game's own profile can override Global, and NVIDIA's predefined profiles set values too. Check the game's profile.
How do I add a game that is not in the list?
Attach the real game exe to a profile, not the launcher. The add-a-game page has a table of exes.
What is a .nip file and how do I import one?
A text file that holds profiles and settings. In NPI use Import, and choose Merge unless you want to replace what is there. LAB
How do I back up my settings?
Use Export and pick current profile, all customized profiles or all profiles. Keep the file outside the driver folder. LAB
Resetting and driver updates
How do I reset everything to default?
Restore profiles one by one, or delete custom profiles. We found no single reset-everything button in the 3.x window. LAB
Do my settings survive a driver update?
The profiles live in the driver, and driver updates can change NVIDIA's predefined profiles. We could not test an update, so keep a .nip backup.
Read the full guide: Keep your settings after a driver update
A profile I deleted keeps coming back, why?
NVIDIA's predefined profiles come from the driver package and can reappear after an update or clean install.
Does the NVIDIA App overwrite my NPI changes?
Both edit the same database, so changing a setting in one can replace the other's value. Use one tool per setting.
DLSS and frame generation
How do I force a DLSS preset in any game?
Set DLSS - Enable DLL Override and DLSS - Forced Preset Letter in the game's profile, apply and restart.
Which preset should I use, K, L or M?
It depends on the game and GPU. The presets page collects NVIDIA's guidance and published comparisons.
Read the full guide: DLSS presets explained (J, K, L, M…) and which to use
How do I check which preset is running?
Turn on the DLSS indicator with its registry value and read it in the game. OFFICIAL
Can I enable Smooth Motion in unsupported games?
Smooth Motion has per-profile rows, and NVIDIA restricts it for some programs. The page lists what the driver data says. LAB
Can I force Multi Frame Generation?
Only in games that already support DLSS Frame Generation, and NVIDIA says MFG needs an RTX 50 GPU. OFFICIAL
Read the full guide: Frame generation and Multi Frame Generation override
Should I use DLSS Swapper, DLSSTweaks or NPI?
NPI changes a driver setting, DLSS Swapper replaces a file, and DLSSTweaks loads a wrapper. The comparison covers risks.

Performance settings
Does it increase FPS?
Not by itself. Most settings trade one thing for another and many are already set by NVIDIA.
What are the best settings?
There is no list that suits every game. The best settings page ranks what the evidence supports.
Should I force Resizable BAR?
Only per game and only if NVIDIA has not already set it. NVIDIA's own list turns it on for 58 games and off for 16. LAB
Which frame limiter is best?
In the published test we found, driver, in-game and RTSS limiters had similar latency, and in-game was smoothest. REPORTED
What FPS cap should I use with G-SYNC?
A few FPS under the refresh rate. The calculator gives the number for your monitor.
Read the full guide: G-SYNC, V-Sync and low latency settings
What shader cache size should I set?
Leave the 16 GB default unless you play many shader-heavy games. No published test shows a larger value fixes stutter. OFFICIAL
Negative LOD bias: Clamp or Allow?
Allow, if you want a negative value to take effect. Clamp blocks it. CODE

When it doesn't work
It won't open or crashes, what do I do?
Follow the decision tree. The usual causes are no NVIDIA driver, a missing .NET Framework 4.8 or a blocked file.
What does DRS_SaveSettings failed mean?
It is a failure writing to the driver's database. The error list explains the causes and what to try.
What does DrsServiceLocator threw an exception mean?
NPI 2.x shows it on a PC without a usable NVIDIA driver. LAB
What does No compatible NVIDIA Driver was detected mean?
NPI 3.x shows it when no NVIDIA driver is reachable. Install or enable the driver and GPU. LAB
