Environmental variables

<!-- This controls the audio driver used by the game.
If set to "auto" (default) a suitable driver is determined automatically
at runtime. You can override the selected driver by setting this variable
to one of the following values:
"pulse" for PulseAudio
"alsa" for ALSA 0.9 PCM audio
"dsp" for OSS /dev/dsp standard audio
"dma" for OSS /dev/dsp DMA audio
"arts" for Analog Realtime Synthesizer (aRts)
"esd" for Enlightened Sound Daemon (EsounD, ESD) -->
<env name="SDL_AUDIODRIVER" value="auto" overwrite="true" />

<!-- This forces the NVIDIA driver to sync on vertical blanking.
Turn this off if you experience performance problems. -->
<env name="__GL_SYNC_TO_VBLANK" value="0" overwrite="false" />

<!-- This determines whether DGA is used (when available) for mouse movement.
In theory this would be more precise, but this does not scale well to
different resolutions. -->
<env name="SDL_VIDEO_X11_DGAMOUSE" value="0" overwrite="true" />

<!-- This changes the mouse acceleration in the game.
Value is of the form "x/y/z" (x, y and z being integers) where x/y is a
fraction specifying the acceleration factor, and z is the movement speed
threshold above which acceleration applies. -->
<!-- <env name="SDL_VIDEO_X11_MOUSEACCEL" value="2/1/0" overwite="true" /> -->

<!-- Set this to 1 to use the XRandR extension for mode switching; may fix
mode selection problems in multiple-monitor configurations. -->
<env name="SDL_VIDEO_X11_XRANDR" value="0" overwrite="true" />

<!-- If you need to use a web proxy, uncomment the variable below and set its
value to "<hostname>:<port>" of your proxy server. Note that this proxy
must support HTTPS connections! -->
<env name="all_proxy" value="" overwrite="false" />
