Nvidia Profile Inspector (NPI) is a 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 normal control panel.
The tool was spun off of the original Nvidia Inspector, which featured an overclocking utility and required you to create a shortcut to launch the profile editor.

_GLOBAL_DRIVER_PROFILE (Base Profile)
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.
1/2 Refresh Rate
This setting is only expose in Nvidia Control Panel for G-Sync monitors supporting refresh rates above 60 Hz.
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.
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.
Override Application Setting
Enhance Application Setting
This is where the specific method of forced/enhanced MSAA is set.
Sparse Grid Supersampling
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.
Full-Screen Sparse Grid Supersamping
User-defined / Off
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 Off.
