Earlier this year, I installed Windows 7 on a new SSD and subsequently re-installed FSX Acceleration, so my sim is quite uncluttered, for once! Fire up times are impressive and with default scenery, FPS is very good. But...
About a month or so ago, I bit the bullet and purchased OrbX PNW. It's as good as its reputation and I have been enjoying the Seattle area with both fixed and rotary wing craft. I've written a couple of missions for PNW and even modified the default "Whiteout" mission so that it works with PNW.
Just a week ago, I installed Nemeth Designs' new Mi-24 Hind, for reviewing.
