8.2 Nvidia Tweaks
These tweaks are for users with a GeForce video card (or better) and Nvidia's proprietary drivers. They are accessed using the bash command export {variable}={value} and then starting the Quake engine from the same command line. Alternatively, recent drivers have a nvidia-settings command which starts up a user-friendly control panel.
Full details of these tweaks are in the Nvidia README, normally installed at "/usr/share/doc/NVIDIA_GLX-1.0/README"
