Well said.  It will be interesting to see how this unfolds.

I have a reasonably powerful computer, getting frame rates in the
20-24 range at high atlitude and 5-10 range at low altitudes near
cities and large airports.

Add the outstanding Capt. Sim C-130 (my favorite) and my computer
would simply stop.

I too will keep FS 2004 for a long time.  We can just hope that Microsoft
releases a fix soon?
