Thanks for the reply kickremi and sorry for not coming back here.. I use the x-plane forums usually. For all the other OSX people out there, I have had great luck with wiping my install of x-plane clean now and again. Keep all your goodies on an external drive and just drag them over after cleaning things up. The things you need to "reset" with your deleted prefs file are minimal, especially if you use a keymapper plugin like x-assign. The two things that kill my FPS are x-plane clouds and scenery. I'm using default mesh, just a few airports and reduced bitdepth of the cloud bitmaps. This gives me anywhere from 30-70 fps while also running OBS on the same machine. YMMV.
