Common tweaks

Disable mouse acceleration

• KDE Plasma: System Settings -> Input devices -> Mouse -> Acceleration profile: Flat
• Gnome: Download "Tweaks" App -> Open it -> Keyboard & Mouse -> Acceleration profile: Flat
• Cinnamon: System Settings -> Mouse and Touchpad -> Acceleration profile: Constant
• Otherwise have a look at the Arch wiki

Use Pipewire instead of PulseAudio

Pipewire gives you much lower audio latency.
