-To build the opengl renderer use:
+Beetle PSX can use an OpenGL or Vulkan renderer instead of the accurate software
+renderer. This will require both a video card and driver that support it, but
+Slackware does not yet provide any Vulkan support, so providing the correct
+system environment for Vulkan is up to you.
+
+To switch between OpenGL and Vulkan renderers configure the video driver in
+RetroArch. This can be done in the menu at 'Settings > Drivers > Video Driver'.

+To build the OpenGL renderer use:
OPENGL=1 ./beetle-psx-libretro.SlackBuild
