Disable V-Sync in GNOME via ~/.drirc configuration

echo '<device screen="0" driver="dri2"><application name="Default"><option name="vblank_mode" value="0"/></application></device>' > ~/.drirc

Disables vertical synchronization (V-Sync) in GNOME by modifying the ~/.drirc file, preventing the GPU from waiting for the monitor's refresh rate, potentially improving frame rates in certain applications but possibly introducing screen tearing.
