@SoulMan:
I agree with you, but I think your mixing two things. One is the "map" display with the "engine". I have no doubt in my mind that if I ported the "map" from FPSCreator to DBP and viewed it, it would scream like a banshee on steroids (or move pretty darn fast).
I think there is a lot of overhead behind the scenes that is being done during the render loop that may not need to be doing anything. For example, as my test showed, it is displaying entities. The only entity is the player marker, so I count 1, and the system is counting around 29. It's cycling through the guns; there are no guns in my test, so why is it looking for something that doesn't even exist?
I am also quite sure that Lee is aware of these issues, but because people were jumping up and down like a Cat on Crack, it was pushed out (but he did warn everyone with the title Early Adapter).
I am also quite sure than when we near V1, things will run A LOT more smoothly. The great news is that we have this version, so we are a step ahead of everyone else. The same principals are going to exist (segments, entities, markers, etc) so as long as we can get used to them, we are on our way.
Don't think of it as a Beta, nor a Release Canidate, think of it as a......
Early Adapter
