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?
