--- Comment #1 from Henri Verbeet hverbeet@gmail.com 2012-09-18 15:05:12 CDT --- I don't know if this is the specific issue you're having, but many Quake 3 based games don't handle long GL extension strings from modern drivers particularly well. On Mesa based drivers you can use the MESA_EXTENSION_MAX_YEAR environment variable to limit the reported GL extensions based on when they were introduced. E.g. MESA_EXTENSION_MAX_YEAR=2003 would limit the extension string to extensions created in or before 2003. The nvidia drivers have a somewhat similar environment variable __GL_ExtensionStringVersion, but based on a driver version instead. __GL_ExtensionStringVersion=17700 would limit the extension string to extensions present in the nvidia 177.x drivers.
