How to Install and Use PowerTools on the Steam Deck

In this tutorial, we will show you how to install and use PowerTools on your Steam Deck.

Steam Deck PowerTools

PowerTools is an incredibly powerful tool that you can utilize to control various aspects of your system on the fly.

Using this tool, you can improve the performance of the Steam Deck in various games and tools. For example, in some emulators, disabling SMT improves the performance of some emulators on the Deck.

You can even use this tool to improve the battery life of your Steam Deck. Not all games will need the full power of the Deck so you can do things such as limiting the clock rate of the core and even decreasing the maximum power usage of your GPU.

Your mileage will differ from game to game, but Powertools allows you to tweak settings for each game on the fly easily.

Hopefully, by the end of this tutorial, you will have a good understanding of how you can put this tool to use.

Overview of the PowerTools Options

Before continuing, let us give you a quick overview of all the options that PowerTools gives you. You can change all of these settings on the fly.

If you aren’t overly interested in each option, skip straight to the next section to install this useful tool.

  • CPU:
    • Advanced – Allows you to configure each of the Steam Deck’s eight threads. You will only want this option if you know what you are doing.
    • SMT – This stands for Simultaneous multithreading and allows you to turn off the secondary thread each core provides. Some games and emulators might perform better with this turned off.

      Essentially you will be limiting your Deck to 4 threads, one per core.
    • Threads – Allows you to modify the number of threads available to the running game.
    • Frequency Limits – Using this option, you can choose the CPU’s minimum and maximum clock rate.
    • Governor – PowerTools even allows you to change the Steam Deck’s CPU Governor. The governor dictates how the Steam Deck will ramp up or down the CPU.
  • GPU:
    • PowerPlay Limits – You can control the maximum amount of power the GPU can consume using this option.
    • Frequency Limits – You can also control the frequency of the GPU by setting its minimum and maximum clock rates.
    • Downclock Memory – This option allows you to force the RAM into lower power mode, which causes it to downclock.
    • Charge Current Limits – PowerTools also allows you to adjust how your Steam Deck charges its battery.

      You can limit the maximum amount of current the Steam Deck will draw from your power adapter using this option.
    • Charge Mode – You can also use this tool to change the charging mode of your Deck. For example, you can tell the Deck to “Discharge“.
    • Charge Limit – The final battery option allows you to set a maximum amount your Deck will charge to.
      Setting this can help your battery’s lifespan and is useful when you keep the Deck pugged in a lot.
    • Persistent Profile – The final option allows you to save your setting changes so they will be applied the next time you load that particular game or application.

      By default, PowerTools does not save any of your settings changes.
