I have FSX installed on its own raptor drive.  I have to install FSUIPC and other related software for my yoke and M-panel.  Should I install this stuff on the same drive, or drive with windows?

Also, I did not install the SDK kit.  I don't paint or develop or anything like that, but should I install this anyways?  Is it needed for any add-ons (free or payware)?

One other question which is OT, but since I'm here.  This is all on a new build and FSX is just a whole 'nother experience on it.  I am getting fantastic FPS and performance except in one instance and that is the top down view - it is wavy, no artifacts or black/white rectangles...just wavy.  Not experienced in any other view.

Is there any particular (of the very few left) tweak that might help with this?  I hardly ever even use that view but I figured I'd try to see if I can smooth it out.  Specs are below, just in case.
