I'm experiencing performance issues when my computer is in "Power Save" mode. How can I avoid this?

If your CPU frequency scaling governor is set to "Power Save" mode, you may experience performance issues in Shadow of the Tomb Raider – Definitive Edition. When playing games, we recommend that you set your CPU frequency scaling governor to "High Performance" mode.

We have developed a tool called GameMode that can enact this process automatically. If GameMode is installed, Shadow of the Tomb Raider – Definitive Edition will automatically set your CPU frequency scaling governor mode. To find out more please visit the GameMode entry on GitHub.

If you wish to manually set your CPU frequency scaling governor mode, please follow the instructions below.

1. From your desktop, open the Terminal application.
2. In Terminal, enter the following line of code: echo performance | sudo tee /sys/devices/system/cpu/cpu*/cpufreq/scaling_governor. Press the Return key.
3. You will be prompted to enter your password. Enter your password, then press the Return key.
4. Your power settings will now be set to "High Performance" mode. Close the Terminal application.

If you wish to change your settings back to "Power Save" mode, simply follow the instructions above and enter the following line of code: echo powersave | sudo tee /sys/devices/system/cpu/cpu*/cpufreq/scaling_governor.
