Nvidia Profile Inspector - PCGamingWiki PCGW (2024)

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.

Sync and Refresh settings

The built-in G-Sync status indicator overlay

ParameterDescriptionFlip IndicatorEnables an on-screen display of frames presented using flip model.Frame Rate LimiterEnables the built-in frame rate limiter of the display drivers at the specified FPS.Frame Rate Limiter ModeControls what mode of the frame rate limiter will be used.GSYNC - Application ModeControls whether the G-Sync feature will be active in fullscreen only, or in windowed mode as well.GSYNC - Application Requested StateIf you know what this setting does, please add a description here.GSYNC - Application StateSelects the technique used to control the refresh policy of an attached monitor.

Allow enables the use of G-Sync, and synchronizes monitor refresh rate to GPUs render target.
Force off and Disallow disables the use of G-Sync.
Fixed Refresh Rate is the traditional fixed refresh rate monitor technology.
Ultra Low Motion Blur (ULMB) uses back light pulsing at a fixed refresh rate to minimize blur.

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 FeatureToggles 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 ModeControls whether the G-Sync feature will be active globally in fullscreen only, or in windowed mode as well.GSYNC - Indicator OverlayEnables 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.GSYNC - Support Indicator OverlayEnables a diagnostics overlay which updates in real time. Can help determine which type of G-SYNC is being requested by a particular 3d application (is it requesting Exclusive Fullscreen or Windowed mode?)Maximum pre-rendered framesControls 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.^[7] This setting does not apply to SLI configurations.

Default is Use the 3D application setting, and it is recommended not to go above 3. Values of 1 and 2 will help reduce input latency in exchange for greater CPU usage.^[8]
When Vsync is set to 1/2 Refresh Rate, a value of 1 is essentially required due to the introduced input latency.^{[citation needed]}

Preferred Refresh RateControls 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.

Highest available - Overrides the refresh rate of the exclusive fullscreen game to whatever is the highest available on the monitor. This setting is automatically used when G-Sync is enabled. Note that this override might not work for all games, in which case an alternative such as Special K might be needed.
Use the 3D application setting / Application-controlled - Uses the refresh rate as requested by the application. If using G-Sync, frame rates above the requested refresh rate will result in screen tearing as G-Sync will go inactive, or V-Sync synchronizing the frame rate to the refresh rate if enabled.

This setting is only exposed in Nvidia Control Panel for monitors supporting refresh rates of at least 100 Hz.

This setting is only effective in DX9/10/11 applications. On Windows 10 (and above) - Fullscreen optimizations must also be disabled.

Triple bufferingToggles triple buffering in OpenGL games. Enabling this improves performance when vertical sync is also turned on.Vertical SyncControls 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 behaviorToggles V-Sync smoothing behavior when V-Sync is enabled and SLI is active.

Official description:^[9]

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 60Hz and 30Hz). 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 ControlToggles Adaptive V-Sync when vertical sync is enabled. Not available when G-Sync is enabled.

Official description:^[10]

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.

ParameterDescriptionAntialiasing - Behavior FlagsThese mostly exist as a method of governing usage of AA from Nvidia Control Panel, though they also affect Inspector as well.

Make sure you are clearing out any flags in this field for a game profile when forcing AA as it will interfere and cause it not to work if you aren't careful.

Antialiasing - Gamma CorrectionGamma correction for MSAA.

Introduced with Half-Life 2 in 2004.

Defaults to ON starting with Fermi GPUs.^[11]

Should not be set to OFF on modern hardware.^{[citation needed]}

Antialiasing - Line gammaApplies gamma correction for singular lines (like wires) as compared to edges.^[12]Antialiasing - ModeDetermines in what mode the anti-aliasing override of the display driver should function in for an application:

Application Controlled - The application itself controls anti-aliasing settings and techniques. The display driver does not override or enhance the anti-aliasing setting the application configures.
Override Application Setting - The display drivers overrides the anti-aliasing setting of the application. This allows one to force anti-aliasing from the display driver. General rule of thumb is to disable any in-game anti-aliasing/MSAA when using this to avoid conflict. There are exceptions though; generally noted in the Anti-Aliasing Compatibility Flags document.
Enhance Application Setting - Enhances the anti-aliasing of a game (e.g. enhance in-game MSAA with TrSSAA), which can provide higher quality and greater reliability for applications with built-in support for anti-aliasing. You must set any anti-aliasing level within the application for this mode to work with the Antialiasing - Setting override.

Use Override Application Setting if the application does not have built-in anti-aliasing settings or if the application does not support anti-aliasing when HDR rendering is enabled. When dealing with modern games, you will most likely want to use this option and not any of the other two.

Enhance Application Setting is entirely dependent on the implementation of MSAA in the application itself. This is can be hit or miss in modern DirectX 10+ games; more often than not either it does not work at all, breaks something, or looks very bad. See Enhance application setting for more information.

DirectX 10+ games ignore this flag and always treat it as Enhance Application Setting.^[13]

Antialiasing - Setting

Explanation of MSAA methods

This is where the specific method of forced/enhanced MSAA or OGSSAA is set.

Antialiasing - Transparency Multisampling

Technical explanation

Interactive example

This enables and disables the use of transparency multisampling.

Antialiasing - Transparency Supersampling

Further Reference

This sets whether Supersampling and Sparse Grid Supersampling is used.

Enable Maxwell sample interleaving (MFAA)

Introduction to 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.
There are some caveats to using this though.

It is not compatible with SGSSAA as far as shown in limited testing.^{[citation needed]}

Depending on the game, MFAA causes visible flickering on geometric edges and other temporal artifacts. Part of this is nullified with downsampling.^{[citation needed]}

It has a minimum framerate requirement of about 40FPS. Otherwise MFAA will degrade the image.

Visible sawtooth patterns with screenshots and videos captured locally.^{[citation needed]}

Incompatible with SLI.^{[citation needed]}

Nvidia Predefined FXAA UsageControls 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 offThis will display a small green icon in the left upper corner if enabled showing whether FXAA is enabled or not.Toggle FXAA on or offFXAA 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.

Turn FXAA On to improve image quality with a lesser performance impact than other antialiasing settings.
Turn FXAA Off if you notice artifacts or dithering around the edges of objects, particularly around text.

Enabling this setting globally may affect all programs rendered on the GPU, including video players and the Windows desktop.

Texture filtering settings

ParameterDescriptionAnisotropic filtering modeToggles the built-in anisotropic filtering override of the display drivers.

16x results in the best quality.

It is possible to add a global override that forces anisotropic filtering on all games. This can solve texture filtering issues that would otherwise exist in games that have mediocre texture filtering. See Why force Anisotropic Filtering (AF)? for details.

Anisotropic filtering settingControls the level of texture filtering the driver override applies, if Anisotropic filtering mode is set to User-defined / Off.

Modern GPUs can perform 4x anisotropic filtering at no performance penalty.^[14]

Prevent anisotropic filteringSimilar 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 optimizationAnisotropic 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.

Select On for higher performance with a minimal loss in image quality
Select Offif you see shimmering on objects

Texture Filtering - Anisotropic sample optimizationAnisotropic sample optimization limits the number of anisotropic samples used based on texel size. This setting only affects DirectX programs.

Select On for higher performance with a minimal loss in image quality
Select Off if you see shimmering on objects

Texture Filtering - Driver Controlled LOD BiasWhen 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]}

Manual LOD bias will be ignored when this is enabled.

Texture Filtering - LOD Bias (DX)

Interactive example

Explanation of LOD bias

The level of detail bias setting for textures in DirectX applications. This normally only works under 2 circ*mstances, both of which requires Driver Controlled LoD Bias set to Off.

When Antialiasing - Mode is set to Override Application Setting or Enhance Application Setting, and an appropriate Antialiasing - Setting is selected.
If you leave the Antialiasing - Mode setting to Application Controlled or Enhance Application Setting but you set the anti-aliasing and transparency setting to SGSSAA (e.g. 4xMSAA and 4xSGSSAA; TrSSAA in OpenGL) then you can freely set the LOD bias and the changes will work without forcing anti-aliasing. This has the side effect that in some games if the game has MSAA, it will act as if you were "enhancing" the game setting even if using Application Controlled.

Notes:

If you wish to use a negative LOD bias when forcing SGSSAA, these are the recommended amounts:

2xSGSSAA (2 samples): -0.5
4xSGSSAA (4 samples): -1.0
8xSGSSAA (8 samples): -1.5

Do not use a negative LOD bias when using OGSSAA and HSAA as they have their own LOD bias.^[15]

Texture Filtering - LOD Bias (OGL)Identical to Texture Filtering - LOD Bias (DX) but applies to OpenGL applications instead.Texture Filtering - Negative LOD biasSome 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.

Has no effect on Kepler GPU's and beyond unless using Nvidia SSAA (SG, OG or Hybrid); can be worked around by setting Antialiasing - Transparency Supersampling to AA_MODE_REPLAY_MODE_ALL.^[16]^[17]

Texture Filtering - QualityThis 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.

Should be set to or left at High Quality if not using a GeForce 8 series GPU or earlier.^{[citation needed]}

Texture Filtering - Trilinear OptimizationTrilinear 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.

Disabled if Texture Filtering - Quality is set to High Quality.

ParameterDescriptionAmbient Occlusion settingThis setting determines what mode of ambient occlusion is to be used when forced in games with no built-in support for it:

Performance
Quality
High Quality

Quality and High Quality are nearly identical, while Performance noticeably lowers the resolution and precision of the effect in many games with less-accurate and stronger shading.^{[citation needed]}

Certain games need Performance to support forced ambient occlusion, such as Oddworld: New 'n' Tasty!^{[citation needed]}

Ambient Occlusion usageSet this to Enabled when using forced ambient occlusion.CUDA - Force P2 StateIf set to OFF it forces GPU into P0 State for compute.Extension limitExtension 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.

If you are using an older OpenGL application, turning this option on may prevent crashing
If you are using a newer OpenGL application, you should turn this option off.

Multi-display/mixed-GPU accelerationThis controls GPU-based acceleration in OpenGL applications and will have no effect on performance on DirectX platforms.^[18]OpenGL - Version OverrideIf you know what this setting does, please add a description here.Optimize for Compute PerformanceThis 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.^[19]Power management modeThis 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.

Adaptive

Automatically determines whether to use a lower clock speed for games and apps.

Works well when not playing games.

Older Nvidia GPU Boost GPUs tend to incorrectly use a lower clock speed.^{[citation needed]}

Setting power management mode from Adaptive to Maximum Performance can improve performance in certain applications when the GPU is throttling the clock speeds incorrectly.^[20]

Optimal power

Same as Adaptive, but will not re-render frames when the GPU workload is idle; instead it will just display the previous frame.

The default power management mode on modern graphics cards.

Prefer maximum performance

Prevents the GPU from switching to a lower clock speed for games and apps.

Works well when playing games.

Wasteful when not using GPU-intensive applications or games.

As Needed (default) - Resources for workstation features are allocated as needed resulting in the minimum amount of resource consumption. Feature activation or deactivation often causes mode-sets.
Moderate pre-allocation - Resources for the first workstation feature activated are statically allocated at system boot and persist thereafter. This will use more GPU and system memory, but will prevent mode-sets when activating or deactivating a single feature. Invocation of additional workstation features will still cause mode-sets.
Aggressive pre-allocation - Resources for all workstation features are statically allocated at system boot and persist thereafter. This will use the most GPU and system memory, but will prevent mode-sets when activating or deactivating all workstation features.
