This got me about 15 fps more. No joke. This one really works. http://www.gamespot.com/pc/sim/microsoftflightsimulatorx/show_msgs.html?topic_id=m-1-31431979
I can fly with everything on Ultra High now (zero traffic though) with at least 15 fps over large cities and 30 fps in other places.
both of the downloadable files have been removed from that forum. Any chance you could post them here, as i wanted to give it a try.
somebody please remind me how I check to see what frame rates I am getting. I have done it before but I forget (and yes FSX is giving me crappy frame rates I can tell)
Shitf + Z twise. 😉
