Nvidia Profile Inspector (NPI) is an open source third-party tool created for pulling up and editing application profiles within the Nvidia display drivers. It works much like the Manage 3D settings page in the Nvidia Control Panel but goes more in-depth and exposes settings and offers functionality not available through the native control panel.
The tool was spun out of the original Nvidia Inspector which featured an overclocking utility and required the user to create a shortcut to launch the profile editor separately.
Nvidia Profile Inspector typically sees maintenance updates released every couple of months, keeping it aligned with changes introduced in newer versions of the drivers, although the project were seemingly on a hiatus between January 19, 2021 and November 13, 2022. An unofficial fork was released in April 2022 with improved support for newer drivers and now no longer available since an official update from the original author.

Anisotropic filtering (AF)
Example of a global override.
- This is an example of why it may be relevant to force high texture filtering globally as some developer's own solutions might not be as high quality as they could be. It is worth noting however that there is a slim but non-existent chance of negative side effects in some games as a result of a forced global driver-level override.
- If any game has a conflict with driver forced texture filtering, Nvidia usually sets a special flag on a profile for texture filtering that disables driver overrides for that game, such as with Far Cry 3 and Doom (2016).
- A quicker way of doing this is to use Nvidia Control Panel and set Anisotropic filtering to

Misc tweaks
Prevent Ansel from being injected/enabled for a specific game
- Using Nvidia Profile Inspector, is becomes possible to disable Ansel on a per-game basis if desired.
- The display drivers loads Ansel related DLL files into all running applications they interface with by default, even if the application does not support or can make use of Ansel. This can cause issues for third-party tools or applications.

Compatibility
Compatibility settings
- Compatibility parameters that allows ambient occlusion, anti-aliasing, and SLI to be used for games, if given an appropriate value.
- HBAO+ Compatibility Flags
- Anti-Aliasing Compatibility Flags
- SLI Compatibility Flags (German)
| Parameter | Description |
|---|---|
| Ambient Occlusion compatibility | Allows HBAO+ to work with any given game. |
| Antialiasing compatibility | Allows various forms of anti-aliasing to work with any given DirectX 9 game. |
| Antialiasing compatibility (DX1x) | Allows various forms of anti-aliasing to work with DirectX 10/11/12 games. Often restricted to MSAA and generally sees little use due to its limited capability. |
| Antialiasing Fix | Avoid black edges in some games while using MSAA.[4] Related to Team Fortress 2 and a few other games as well, where it is enabled by default. |
| SLI compatibility bits | Allows SLI to work in any given DirectX 9 game. |
| SLI compatibility bits (DX10+DX11) | Allows SLI to work in any given DirectX 10/11 game. |
| SLI compatibility bits (DX12) | Allows SLI to work in any given DirectX 12 game. |
Sync and Refresh
Sync and Refresh settings
The built-in G-Sync status indicator overlay
- See Frame rate (FPS) for relevant information.
- The built-in frame rate limiter of the Nvidia display drivers introduces 2+ frames of delay, while RTSS (and possibly other alternatives) only introduces 1 frame of delay.[5]
- AnandTech - Triple Buffering: Why We Love It - Recommended reading about triple buffering/Fast Sync.
| Parameter | Description |
|---|---|
| Flip Indicator | Enables an on-screen display of frames presented using flip model. |
| Frame Rate Limiter | Enables the built-in frame rate limiter of the display drivers at the specified FPS. |
| Frame Rate Limiter Mode | Controls what mode of the frame rate limiter will be used. |
| GSYNC - Application Mode | Controls whether the G-Sync feature will be active in fullscreen only, or in windowed mode as well. |
| GSYNC - Application Requested State | If you know what this setting does, please add a description here. |
| GSYNC - Application State | Selects the technique used to control the refresh policy of an attached monitor.
It is highly recommended to change this using the Nvidia Control Panel > Manage 3D Settings > Monitor Technology instead to properly configured this and related parameters. |
| GSYNC - Global Feature | Toggles the global G-Sync functionality. It is recommended to change this using the Nvidia Control Panel > Set up G-SYNC instead to properly configured this and related parameters. |
| GSYNC - Global Mode | Controls whether the G-Sync feature will be active globally in fullscreen only, or in windowed mode as well. |
| GSYNC - Indicator Overlay | Enables a semi-transparent on-screen status indicator of when G-Sync is being used. If G-Sync is not being used, the indicator is not shown at all. |
| Maximum pre-rendered frames | Controls how many frames the CPU can prepare ahead of the frame currently being drawn by the GPU. Increasing this can result in smoother gameplay at lower frame rates, at the cost of additional input delay.[6] This setting does not apply to SLI configurations.
|
| Preferred Refresh Rate | Controls the refresh rate override of the display drivers for games running in exclusive fullscreen mode. This also dictates the upper limit of the G-Sync range, as G-Sync will go inactive and the screen will start to tear at frame rates above the configured refresh rate, or V-Sync will kick in and sync the frame rate to the refresh rate if enabled.
|
| Triple buffering | Toggles triple buffering in OpenGL games. Enabling this improves performance when vertical sync is also turned on. |
| Vertical Sync | Controls vertical sync, or enables Fast Sync. Fast-Sync is essentially triple buffering for DirectX games, and is only applicable to frame rates above the refresh rate when regular V-Sync is disabled. |
| Vertical Sync Smooth AFR behavior | Toggles V-Sync smoothing behavior when V-Sync is enabled and SLI is active.
Official description:[8] Smooth Vsync is a new technology that can reduce stutter when Vsync is enabled and SLI is active. When SLI is active and natural frame rates of games are below the refresh rate of your monitor, traditional Vsync forces frame rates to quickly oscillate between the refresh rate and half the refresh rate (for example, between 60 Hz and 30 Hz). This variation is often perceived as stutter. Smooth Vsync improves this by locking into the sustainable frame rate of your game and only increasing the frame rate if the game performance moves sustainably above the refresh rate of your monitor. This does lower the average framerate of your game, but the experience in many cases is far better. |
| Vertical Sync Tear Control | Toggles Adaptive V-Sync when vertical sync is enabled. Not available when G-Sync is enabled.
Official description:[9] Nothing is more distracting than frame rate stuttering and screen tearing. The first tends to occur when frame rates are low, the second when frame rates are high. Adaptive VSync is a smarter way to render frames using Nvidia Control Panel software. At high framerates, VSync is enabled to eliminate tearing. At low frame rates, it's disabled to minimize stuttering. |
Antialiasing
Anti-aliasing settings
- See Anti-aliasing (AA) for relevant information.
- Anti-Aliasing Compatibility Flags
| Parameter | Description |
|---|---|
| Antialiasing - Behavior Flags | These mostly exist as a method of governing usage of AA from Nvidia Control Panel, though they also affect Inspector as well.
|
| Antialiasing - Gamma Correction | Gamma correction for MSAA.
|
| Antialiasing - Line gamma | Applies gamma correction for singular lines (like wires) as compared to edges.[11] |
| Antialiasing - Mode | Determines in what mode the anti-aliasing override of the display driver should function in for an application:
|
| Antialiasing - Setting |
This is where the specific method of forced/enhanced MSAA or OGSSAA is set. |
| Antialiasing - Transparency Multisampling |
|
| Antialiasing - Transparency Supersampling |
|
| Enable Maxwell sample interleaving (MFAA) |
This enables Nvidia's Multi Frame Anti Aliasing mode. This only works in DXGI (DX10+) and requires either the game to have MSAA enabled in the game or MSAA to be forced.
What it does is change the sub sample grid pattern every frame and then is reconstructed in motion with a "Temporal Synthesis Filter" as Nvidia calls it.
|
| Nvidia Predefined FXAA Usage | Controls whether Nvidia's FXAA implementation is allowed to be enabled for an application through Nvidia Control Panel (primarily) or Nvidia Profile Inspector. |
| Toggle FXAA indicator on or off | This will display a small green icon in the left upper corner if enabled showing whether FXAA is enabled or not. |
| Toggle FXAA on or off | FXAA is a fast shader-based post-processing technique that can be applied to any application, including those which do not support other forms of hardware-based antialiasing. FXAA can also be used in conjunction with other antialiasing settings to improve overall image quality.
|
Enhance application setting
- When overriding the in-game MSAA fails, you can instead replace (enhance) the in-game MSAA with the Nvidia MSAA technique of your choice.
- These usually require anti-aliasing compatibility flags to work properly in DirectX 9 applications; see the List of anti-aliasing compatibility flags.
- The level of supersampling must match a corresponding level of MSAA. For example, if 4x MSAA is used, then 4x Sparse Grid Supersampling must be used.
- In OpenGL
Supersamplingis equivalent toSparse Grid Supersampling. Ergo, 4xMSAA+4xTrSSAA will give you 4xFSSGSSAA in OpenGL games that work.
Supersampling
- Inexpensive
- Does not require MSAA to work
- Only works on alpha-tested surfaces
Full-Screen Sparse Grid Supersamping
- Extremely high-quality supersampling
- Works on the entire image
- Requires MSAA to work
- Very expensive
Texture Filtering
Texture filtering settings
- See Anisotropic filtering (AF) for relevant information.
| Parameter | Description |
|---|---|
| Anisotropic filtering mode | Toggles the built-in anisotropic filtering override of the display drivers.
|
| Anisotropic filtering setting | Controls the level of texture filtering the driver override applies, if Anisotropic filtering mode is set to User-defined / Off.
|
| Prevent anisotropic filtering | Similar to AA Behavior Flags, if this is set to On it will ignore user-defined driver overrides. Some games default to this, such as Quake 4, RAGE, Doom (2016), Far Cry 3, and Far Cry 3: Blood Dragon.
|
| Texture filtering - Anisotropic filter optimization | Anisotropic filter optimization improves performance by limiting trilinear filtering to the primary texture stage where the general appearance and color of objects is determined. Bilinear filtering is used for all other stages, such as those used for lighting, shadows, and other effects. This setting only affects DirectX programs.
|
| Texture Filtering - Anisotropic sample optimization | Anisotropic sample optimization limits the number of anisotropic samples used based on texel size. This setting only affects DirectX programs.
|
| Texture Filtering - Driver Controlled LOD Bias | When using SGSSAA with this enabled will allow the driver to compute its own negative LOD bias for textures to help improve sharpness (at cost of potential for more aliasing) for those who prefer it. It's generally less than the fixed amounts that are recommended.[citation needed]
|
| Texture Filtering - LOD Bias (DX) |
The level of detail bias setting for textures in DirectX applications. This normally only works under 2 circumstances, both of which requires Driver Controlled LoD Bias set to
Notes:
|
| Texture Filtering - LOD Bias (OGL) | Identical to Texture Filtering - LOD Bias (DX) but applies to OpenGL applications instead. |
| Texture Filtering - Negative LOD bias | Some applications use negative LOD bias to sharpen texture filtering. This sharpens the stationary image but introduces aliasing ("shimmering") when the scene is in motion. This setting controls whether negative LOD bias are clamped (not allowed) or allowed. |
| Texture Filtering - Quality | This setting allows you to decide if you would prefer performance, quality, or a balance between the two. If you change this using the Nvidia Control Panel, the control panel will make all of the appropriate texture filtering adjustments based on the selected preference.
|
| Texture Filtering - Trilinear Optimization | Trilinear optimization improves texture filtering performance by allowing bilinear filtering on textures in parts of the scene where trilinear filtering is not necessary. This setting only affects DirectX applications.
|
Common
Common settings
| Parameter | Description |
|---|---|
| Ambient Occlusion setting | This setting determines what mode of ambient occlusion is to be used when forced in games with no built-in support for it:
|
| Ambient Occlusion usage | Set this to Enabled when using forced ambient occlusion.
|
| CUDA - Force P2 State | If set to OFF it forces GPU into P0 State for compute. |
| Extension limit | Extension limit indicates whether the driver extension string has been trimmed for compatibility with particular applications. Some older applications cannot process long extension strings and will crash if extensions are unlimited.
|
| Multi-display/mixed-GPU acceleration | This controls GPU-based acceleration in OpenGL applications and will have no effect on performance on DirectX platforms.[17] |
| OpenGL - Version Override | If you know what this setting does, please add a description here. |
| Optimize for Compute Performance | This setting is intended to provide additional performance to non-gaming applications that use large CUDA address spaces and large amounts of GPU memory when run on graphics cards based on second-generation Maxwell GPUs. Graphics cards based on other architectures do not utilize this setting.[18] |
| Power management mode | This allows you to set a preference for the performance level of the graphics card when running 3D applications. It is recommended to configure this on a per-game basis using game-specific profiles, to prevent unnecessary power draw while not gaming.
|
| Shader cache | Enables or disables the shader cache, which saves compiled shaders to your hard drive to improve game performance.[20]
|
| Show PhysX Visual Indicator | Enables an on-screen status indicator of when PhysX is being used. If PhysX is not being used, the indicator is not shown at all. |
| Threaded optimization | Allows OpenGL applications to take advantage of multiple CPUs.
|
SLI
SLI settings
| Parameter | Description |
|---|---|
| Antialiasing - SLI AA | This determines whether a Nvidia SLI setup splits the MSAA workload between the available GPUs.[21] |
| Disable SLI (Explicitly set through NVAPI) | If you know what this setting does, please add a description here. |
| Number of GPUs to use on SLI rendering mode | Forces all rendering modes to utilize either one, two, three or four gpu's for rendering. |
| NVIDIA predefined number of GPUs to use on SLI rendering mode | Forces DX9 and OpenGl to utilize either one, two, three or four gpu's for rendering. |
| NVIDIA predefined number of GPUs to use on SLI rendering mode on DX10 | Forces DX10, DX11 and DX12 to utilize either one, two, three or four gpu's for rendering. This can effect total bandwidth not using four but using four rather than 2 can cause artifacting in certain games. |
| NVIDIA predefined SLI mode | Forces DX9 and OpenGl to render using AFR, AFR 2, SFR (CFR) or Single Gpu Mode with Sli Enabled in Nvidia Control Panel. |
| NVIDIA predefined SLI mode on DX10 | Forces DX10, DX11 and DX12 to render using AFR, AFR 2, SFR (CFR) or Single Gpu Mode with Sli Enabled in Nvidia Control Panel. Almost all games require AFR in DX11. Nvlink with turing allows for CFR to be used in several games where AFR is not even usable. |
| SLI indicator | Enables a semi-transparent on-screen status indicator of when SLI is being used and how the workload is split between the cards. |
| SLI rendering mode | Forces Base sli rendering mode AFR, AFR 2, SFR (CFR) or Single Gpu Mode with Sli Enabled in Nvidia Control Panel (Good for quick switching to test fps). Using this setting will override compatibility settings set in the sli section, this is why I call it Base Sli. |

Unknown
Unknown settings
- These are unknown settings or overrides that Nvidia Profile Inspector is not aware of what they determine or controls.
- Most of these are game-specific overrides only applicable to a few games, or new flags that were introduced in newer versions of the display drivers.
- Not all unknown settings can be properly exported and imported at will. If a built-in profile using one of those have been removed, the recommendation is to reinstall the display drivers to ensure they are restored fully.
| Parameter | Description |
|---|---|
| 0x00666634 | When set to 1 (0x00000001), marks applications covered by the profile as a Silk Test App. This is required for the "SILK Smoothness" setting to take effect. |
| Parameter | Description |
| 0x10834FEE | When the parameter is set to 2 (0x0020000) the value modifies the speed of everything including the framerate that windows handles therefore it is better disabled because it renders ineffective the value of Nvidia framerate limiter v3 please refrain from modifying this value and leave it at the value 0x00000000 so that all applications work naturally |

- "The 'maximum pre-rendered frames' function operates within the DirectX API and serves to explicitly define the maximum number of frames the CPU can process ahead of the frame currently being drawn by the graphics subsystem. This is a dynamic, time-dependent queue that reacts to performance: at low frame rates, a higher value can produce more consistent gameplay, whereas a low value is less likely to introduce input latencies incurred by the extended storage time (of higher values) within the cache/memory. Its influence on performance is usually barely measurable, but its primary intent is to control peripheral latency."

- "Shaders are used in almost every game, adding numerous visual effects that can greatly improve image quality (you can see the dramatic impact of shader technology in Watch Dogs here). Generally, shaders are compiled during loading screens, or during gameplay in seamless world titles, such as Assassin's Creed IV, Batman: Arkham Origins, and the aforementioned Watch Dogs. During loads their compilation increases the time it takes to start playing, and during gameplay increases CPU usage, lowering frame rates. When the shader is no longer required, or the game is closed, it is discarded, forcing its recompilation the next time you play.
In today's 337.88 WHQL drivers we've introduced a new NVIDIA Control Panel feature called "Shader Cache", which saves compiled shaders to a cache on your hard drive. Following the compilation and saving of the shader, the shader can simply be recalled from the hard disk the next time it is required, potentially reducing load times and CPU usage to optimize and improve your experience.
By default the Shader Cache is enabled for all games, and saves up to 256MB of compiled shaders in %USERPROFILE%\AppData\Local\Temp\NVIDIA Corporation\NV_Cache. This location can be changed by moving your entire Temp folder using Windows Control Panel > System > System Properties > Advanced > Environmental Variables > Temp, or by using a Junction Point to relocate the NV_Cache folder. To change the use state of Shader Cache on a per-game basis simply locate the option in the NVIDIA Control Panel, as shown below."

- "SLI AA essentially disables normal AFR rendering, and in 2-way mode will use the primary GPU for rendering + forced AA, while the secondary GPU is only used to do AA work.
In SLI8x mode for example, each GPU would then do 4xMSAA after which the final result becomes 4xMSAA+4xMSAA=8xMSAA.
This can be useful in games without proper SLI support, so at least the second GPU is not just idling.
However it unfortunately only works correctly in OpenGL, and there will be no difference in temporal behavior between for example normal forced 4xMSAA+4xSGSSAA and SLI8x+8xSGSSAA in DX9."
