Yeah I also thought I had better try it after posting about it. Frames dropped from +/- 50 at Nice looking West (22L) and immediately dropped to +/- 14 the moment I turned East and brought it into view. Funny thing is, even at such low FPS the sim was quite manageable and not 1 stutter. Kudos to the creator, I am quite convinced we are going to see some talent coming through with this release.
Now the only other thing we have to do is teach those using multiplayer not to sit on the active for an hour or more!
