What is P State NVIDIA?
P-States are GPU active/executing performance capability and power consumption states. P-States ranges from P0 to P15, with P0 being the highest performance/power state, and P15 being the lowest performance/power state. Each P-State, if available, maps to a performance level.
How do I change my NVIDIA P State?
How to: Open NVIDIA Profile Inspector, scroll down to 5 – Common and set CUDA – Force P2 State to OFF. Press Apply changes on the upper right corner and close the tool. As a result your compute workloads will use the maximum memory clock from the P0 state.
What is P2 State?
Several years ago, NVIDIA added a driver feature called ‘CUDA – Force P2 State’ which is the default setting. This performance analysis uses an RTX 3080 to showcase 15 PC games using this driver feature, off versus on, with our latest recommended GeForce Game Ready driver, and the latest version of Windows 10.
What is Nvapi?
NVAPI is NVIDIA’s core software development kit that allows direct access to NVIDIA GPUs and drivers on all Microsoft® Windows® platforms. NVAPI provides support for categories of operations that range beyond the scope of those found in familiar graphics APIs such as DirectX and OpenGL.
What is Nvidia persistence mode?
Persistence Mode is the term for a user-settable driver property that keeps a target GPU. initialized even when no clients are connected to it.
How do I change the power limit on my graphics card?
If you wish to adjust the Power Cap Limit follow these steps:
- Determine the current, default and maximum power limit as follows: nvidia-smi -q | grep ‘Power Limit’
- Ensure that persistence mode is being used.
- Increase the SW Power Cap limit for all GPUs as follows, where xxx is the desired value in watts:
How do I use Nvidia profile inspector?
First steps for tweaking driver settings
- Download and run the latest version of the Profile Inspector, see Installation.
- Using the Profiles list on top of the window, select the game-specific profile if one exists.
- Tweak the desired settings.
- Finally click on Apply changes to save the changes.

What is APU CPU GPU?
APUs: What are they? An APU, or Accelerated Processing Unit is the term given to a series of processors that basically act as a CPU (Central Processing Unit) and a GPU (Graphics Processing Unit) on a single chip die. They are essentially processors with in-built graphics.
Does nvidia need Persistenced?
It is strongly recommended, though not required, that the daemon be run as a non-root user for security purposes. The daemon may either be started with root privileges and the –user option, or it may be run directly as the non-root user.
Is it good to increase GPU power limit?
Increasing this limit won’t do any harm to your system but if you decrease the power below the normal level then it will affect your PC’s performance. If the card isn’t able to draw enough power or if the power limit is too low, the core clock of your GPU will start throttling hence it will lose its performance.
