OK, I'm sure I'm going to get blasted for this as being completely bogus but... Been playing with the settings to see what works best for my system. Have most sliders at midway or above. Just for the heck of it I moved the "Level and Detail" slider under the Scenery tab to far right "Large"I have my frame rates locked at 20 and on the runway at KATL I was getting around 14-16 FPS. When I moved the above slider my rates pegged at 20 and stayed there. No clue why but I'll take it!

Well, I concur it does help for me too!

Well I'm sure glad. I really debated about even posting this. Sounds so off the wall.
