2. Tweak Game Settings

We can also increase the Sons of the Forest performance by changing the in-game settings. That may increase your gaming experience. The following are the steps:

  • First, Restart your PC.
  • Launch the steam and start Sons of the Forest from the steam library.

Game Mode is a feature that can help improve gaming performance on your PC. When enabled, Game Mode prioritizes your PC’s resources toward the game you are playing, allowing for better overall performance.

Game Mode works by limiting background processes and other non-essential tasks to free up resources for the game. It can also adjust the CPU and GPU settings to prioritize performance over power efficiency. To enable the Game, follow these steps:

  • Open the Settings app and click on the Gaming section.
    • Click on the Game Mode tab.
    • Toggle the switch to turn on Game Mode.

Once Game Mode is enabled, Windows will automatically detect when you are playing a game and optimize your system resources accordingly.

3. Update your Graphics Card Drivers

The first thing you need to do is to check if your graphics card drivers are up to date. Outdated drivers can cause performance issues and prevent the game from using your GPU or CPU. To update your graphics card drivers, follow the steps below:

  • Press Windows Key + X and select Device Manager.
  • Expand the Display Adapters category.
  • Right-click on your graphics card and select Update Driver.
  • Select Search automatically for updated driver software and wait for Windows to search for the latest drivers.

4. Check your Power Settings

Windows has power-saving features that can reduce the performance of your hardware. This can also produce a bad effect on the utilization of CPU/GPU. If there is less power then the CPU/GPU will not give you proper performance.

To make sure that your CPU and GPU are not being throttled, follow the steps below:

  • Press Windows Key + X and select Power Options.
  • Select High performance.
  • If you don’t see the High-performance option, click on Show additional plans and select High performance.
  • Restart your computer and launch the game again.

5. Use a Dedicated Graphics Card

Using a dedicated graphics card is generally preferred over an integrated graphics card as it offers better and more stable graphics performance. If possible, it is recommended that you use a dedicated graphics card instead of an integrated one.

6. Turn Off V-Sync

By default, Sons of the Forest has V-Sync or FreeSync enabled, which may conflict with the game’s refresh rate and the monitor’s refresh rate.
