Does Priority command require LinuxGameMode to be installed on Ubuntu systems?

The Priority documentation doesn’t mention requiring LinuxGameMode to be installed, but the documentation for GameMode mentions its use for the Priority feature. When I try running code with Priority on Ubuntu (without LinuxGameMode), I get a long (200-300ms) delay at the start of every trial but no error messages. Commenting out the Priority commands resolves this delay issue, making me wonder that I need Game Mode installed for it to work?
