The only other thing that I can think of that may be affecting the Furnishing display at a distance is the LOD option and Occlusion Culling.

Both of these settings are in the System Configuration menu, under the Graphics settings tab.
Make sure the LOD setting (Low-detail models) is set to off (uncheck it).
And set Occlusion Culling to off by unchecking it, this option here is probably the one making the furnishing pop in/out moving the camera.

I would test one at a time and both to see if it helps.
