Some others I've noticed after using MacOS briefly: Disable font anti-aliasing and enable full hinting (essential to get sharp fonts without needing a slower and more expensive 4K monitor) Disable vsync (necessary for reducing latency to the absolute minimum when you don't care about tearing; requires Xorg) Disable window decorations (for a pseudo-fullscreen mode that leaves the panel visible) Disable mouse acceleration Disable mouse wheel acceleration Change mouse polling rate Set keyboard auto-repeat to arbitrary values (I use 72Hz auto-repeat with 200ms delay) Remap colors for compatibility with display hardware with non-standard black/white levels (I have a DVI to VGA converter that expects TV black level but computer white level) Send arbitrary DDC commands to the monitor (e.g. to change brightness) Disable and enable the mouse in software (to prevent accidentally waking from power saving with mouse movements) Switch virtual desktops by moving the mouse to the corner of the screen and then moving the mouse wheel (corners have infinite size for the purposes of Fitt's law, and mouse wheel inputs should only change presentation of data not the data itself, which means there's no danger from missing the corner, so this is the best way of quickly switching desktops by mouse).
