HI ?
first of all some questions :
what will you use the 3d view for ?
&Are you using opengl engine ?
you may try to hide everything that will not be visible in your 3d view, (things like internal walls, furniture objects..etc are generally not necessary for an exterior 3d scene)..this will make a huge difference.
and/or use a partial selection especially if you are using the 3d for working...
