Hi Brad,
Thanks! It does use frame rates due mostly to all of the objects and the fact that the trees are almost doubled from the ORBX default. I watched the FPS very carefully as I built since I knew it would be a problem. I run it on 3 screens totaling 5040 X 1050 resolution at 32 FPS locked and works pretty well on P3Dv3 which is lower than v4. However, I do not use shadows when I am running because they are heavy frame rate killers and also have to watch how densely clouded the weather is. You can really gain some frames by turning shadows down partially.....quality, cast distance, etc. Also, you can gain frames by turning vegetation density down a notch and you hardly notice the change in tree density but it does have a lowering effect on frames since there are so many trees.
