Explains this is expected behavior.
If I have configured custom setting in the performance tab, Intel® Arc Control Fan curve settings disappear after driver upgrade.
When a driver gets upgraded, some settings might change and the stored user settings might cause issues. The Arc Control app and service need to re-initialize the values. Because of this, a reboot is required after the driver update and before any settings customization in Arc Control.
At the end of the new driver installation process you can
- Click the Required Reboot button in the last driver installer screen.
or
- Click Finish button if you have to save work in currently open apps and then manually reboot your system.
