## Here are some configuration options for Linux Client Testers.

## - Avoids using any FMOD STUDIO audio driver.
#export LL_BAD_FMODSTUDIO_DRIVER=x
## - Avoids using any OpenAL audio driver.
#export LL_BAD_OPENAL_DRIVER=x

## - Avoids using the FMOD Studio or FMOD Ex PulseAudio audio driver.
#export LL_BAD_FMOD_PULSEAUDIO=x
## - Avoids using the FMOD Studio or FMOD Ex ALSA audio driver.
#export LL_BAD_FMOD_ALSA=x

# Completely prevent gamemode from enabling even if set to true in the settings
# This can be useful if you run Alchemy on a battery-operated device (i.e. laptop)
# export DISABLE_GAMEMODE=1

## - Avoids the optional OpenGL extensions which have proven most problematic
##   on some hardware.  Disabling this option may cause BETTER PERFORMANCE but
##   may also cause CRASHES and hangs on some unstable combinations of drivers
##   and hardware.
## NOTE: This is now disabled by default.
#export LL_GL_BASICEXT=x

## - Avoids *all* optional OpenGL extensions.  This is the safest and least-
##   exciting option.  Enable this if you experience stability issues, and
##   report whether it helps in the Linux Client Testers forum.
#export LL_GL_NOEXT=x

## - For advanced troubleshooters, this lets you disable specific GL
##   extensions, each of which is represented by a letter a-o.  If you can
##   narrow down a stability problem on your system to just one or two
##   extensions then please post details of your hardware (and drivers) to
##   the Linux Client Testers forum along with the minimal
##   LL_GL_BLACKLIST which solves your problems.
#export LL_GL_BLACKLIST=abcdefghijklmno

##   you're building your own viewer, bear in mind that the executable
##   in the bin directory will be stripped: you should replace it with
##   an unstripped binary before you run.
