I have returned to RB3D with my updated rig and I am using HAG. The horizon line seems to be nothing but a wide off white jagged band. Any solution for this

There are some variances with running in True GLIDE,OpenGL with the wrapper,or DD. There are settings for "near" and "far" terrain view in the PREFERENCES/GRAPHICS/GRAPHICS OPTIONS which may help. Turn FOG on,this may help. There is a utility to stretch the terrain view even farther,I can E it to you but it is a pretty bad hit on FR. You may be unable to completely get rid of the "pyramids".
Others responding may have better advice
