That's possible, but currently the problem is that FlightGear will not
start at all at 16bpp with --enable-clouds, because of this:
if ( fgGetBool("/sim/rendering/clouds3d") ) {
glutInitDisplayMode( GLUT_RGB | GLUT_DEPTH | GLUT_DOUBLE | GLUT_ALPHA );
} else {
glutInitDisplayMode( GLUT_RGB | GLUT_DEPTH | GLUT_DOUBLE );
}
Here's what I get:
GLUT: Fatal Error in fgfs: visual with necessary capabilities not found.
All the best,
David
