I did some experimenting with fgReshape, adding a simple test at the
start to return if the width, height, and panel visibility were
unchanged, but saw no framerate improvement. Upon closer examination,
the only OpenGL-related things in the function are
glViewport( 0, (GLint)(height - view_h), (GLint)(width), (GLint)(view_h) );
and
ssgSetFOV( globals->get_current_view()->get_h_fov(),
globals->get_current_view()->get_v_fov() );
Does glViewport have any significant overhead? Don't we have to call
it every frame anyway (I know the panel code does so).
All the best,
David
