 Only available for the GTK-2 client.
+Though the OpenGL drawing mode apparently works even without the GLX extension switched on for the XServer, \\
+the older GTK-2 clients will crash at startup if the GLX extension would be not available:
+<code bash>
+# gcfclient2-1.10.0 -opengl
+Xlib:  extension "GLX" missing on display ":0.0".
+Segmentation fault
+</code>
+The newer GTK-2 clients will work still, if the necessary libraries ''libGL.so.1'' , ''libGLU.so.1'' and ''libglut.so.3'' are available on the system:
+<code bash>
+# crossfire-client-gtk2-1.70.0 -opengl
+[  INFO  ] (gtk-v2::init_glx_opengl) Direct rendering is not available!
+[  INFO  ] (gtk-v2::opengl_common) Maximum texture size is 2048
+[  INFO  ] (gtk-v2::init_image_cache_data) Init Image Cache
+</code>
+When OpenGL had not been available at [[client compiling]] time, then the client will fall back to Pixmap mode, and prints to stderr
+<code bash>
+# crossfire-client-gtk2-1.70.0 -opengl
+[WARNING ] (main.c::init_windows) client not compiled with opengl support.  Ignoring -opengl
