I fly almost soley photo-real sceneries. The sceneries worked just fine until I installed the new stuff, but like I say I am getting probably over 40 frames per second with it, so its not a video card issue, its the in-game camera. I don't think I need the patch though, I'll go revert back to the original AFPD and backup the extra planes and scenery from the addons and put them back in there manually. That way I can hopefully have it all without changing the nit-picky details of the files that make the thing work. Thanks for the advice, rajul!
