Description

Xonotic is a fast-paced, chaotic, and intense multiplayer first person shooter, focused on providing basic, old style deathmatches.

This game is based on DarkPlaces engine, a heavily modified id Tech 3 (Quake III Arena) engine. You must be using a card supported by the nouveau video driver.

Setup

  1. Ensure the nomodeset and nouveau.modeset=0 kernel parameters are not set in your bootloader configuration
    • You can see your current kernel options by running cat /proc/cmdline
  2. Ensure the file /etc/X11/xorg.conf does not exist, or is a valid file that uses the nouveau driver
  3. Shut your system down entirely, then start it up again
  4. If using a live image to test, ignore the above steps and simply boot the system from the live image with default options
  5. Ensure that glxinfo | grep 'OpenGL renderer' does not return OpenGL renderer string: Software Rasterizer or llvmpipe
  6. Install the xonotic package with the command su -c 'yum install xonotic'

How to test

  1. Launch 'xonotic-sdl-wrapper' from a terminal
  2. Edit the game "Settings":
    1. In "Video" set "Resolution" to native for your display and have "Fullscreen" checked. "GLSL" should be enabled, if your card and driver supports OpenGL 2.0 shaders.
    2. Enable FPS indicator in "Misc".
  3. Play Level 1 in singleplayer.
  4. In "Effects" set "Quality preset" to highest possible, i.e. "Ultra" + increase/enable more aggressive effects. Lower "Quality preset" if you get under 10 FPS.
  5. Continue playing, use all the weapons in the game.
  6. In "Video" set "Anisotropy" to max setting and try also "Antialiasing" or "High-quality frame buffer".
  7. Continue playing, use all the weapons in the game.
  8. Enable "Vertical Synchronization". This may result in better performance when playing with low FPS settings.
  9. Continue playing, use all the weapons in the game.
  10. Quit Xonotic

Expected Results

  1. The game should not crash at any point.
  2. There should be no obvious misrendering (flickering, transparent walls, polygons instead of surfaces...)
  3. You can see reflections on surfaces, shadows, motion blur effect (if enabled). If you see distinct polygons instead of smooth surfaces, this is a rendering bug.
  4. FPS should be usable and stable on any modern GPU. You can balance it using lower "Quality preset".
