Tried a couple low flights over the Las Vegas Strip, but always ends in a crash into nothing it seems?FSX Acceleration - Extremely Dense Scenery Complexity

Interesting how folks seem to report things in "waves" of information... there's another thread about an unlucky sim-pilot crashing into nothing going under an airport overpass. The other day, I was reading about crashing into the new bridges in Vancouver+.You can try turning off collision detection to see if that helps.What is probably happening is that you've clipped a piece of scenery where the collision detection box goes beyond the actual model, which seems to be common enough in FSX. In the words of the "Time Bandits", and to my mind, one of the greatest throw-away lines ever written for the movies: "Oh, so that's what the invisible wall looks like!"Jeff ShylukSenior Staff Reviewer, AVSIM

I had a similar problem whenever I flew from MDW toward downtown Chicago I would consistantly crash. Found out that it was caused by the Meigs scenery I had installed...disabled Meigs and the problem went away.

Try flying low down the Strip in Las Vegas, about half way down I hit an unseen wall with Acceleration... :)
