I see it all the time, if I play early in the AM, fps will run at 20 and everything looks so dam good, then 800am roles around and BAM! all of a sudden the fps will drop below 20 sometimes never exceeding 15, and things on the ground look like a Abstract painting, and hour or 2 later it will be back again, only to do the exact same thing around lunch hour, and then forget about the 3-8pm time frame, because thats when the majority of people are going to be on, and the best part of all this is that since the sim uses the Azure network, you not only have to deal with all the players in the game, but all the other traffic using Azure, Big Corporations, MS win online users (alright that one might not be a big hit last time I saw) but you get the idea.
Thats the biggest reason I didnt buy the game, (one of my boys bought it for me to help get over the wife’s death), if all your content is coming from the net, then your pretty much reliant on it. Since playing offline seems to look more or less like the FSX or P3D or Xplane.
