I Get Your Version

// Now OF COURSE starting with catalyst 5.13 or so they decreased the number
// in GL version by 3000 or so. So GL version of Catalyst 6.11 is 2.0.1072
// (whereas Catalyst 5.3 is 2.0.4955).
//
// So we also detect the driver DLL version (5.3 is ati2dvag, 6.14.10.6517).
//
// Wonderful!
if( version <= 20 && buildVersion <= 4955 && driverNameString ==
"ati2dvag" && (driverVersion <=
windriverutils::VersionInfo(6,14,10,6517)) )
{
   hasVertexProgram = false;
   printf_console( "GL: disabling vertex programs due to Radeon
driver bugs\n" );
}
