Yeah, that's what I would suggest too. Wireframe. I don't even use the shaded modes at all, especially when dealing with huge models. If you use wireframe, it will refresh MUCH quicker, and if you set your render quality to "Sketch" while you're working, you can just hit the F9 key and get a very quick preview of how your model looks......much faster than waiting for the screens to refresh. Would it make you feel any better if I told you that Vue isn't any slower than 3ds max 4? Vue might be a little faster, for that matter.
