Very interesting map, Tactical Gamer admin team was looking it over yesterday as a possibility to include it in our mod set to run on the servers, unfortunately until a few issues are fixed and the second island is complete (looks like you've already done this) we cannot include it, although personally I'm gonna keep pushing this map, once it is out of beta I'd love to play it.
The biggest issue we found on the map was spots of heavy FPS hits around some tree lines but the biggest affected area was the small island on the north east sector, looked like a prison camp, causing FPS loss of around 30-40 frames.
Apart from those minor issues, this is one of the best maps I have seen, so much detail and attention has been put into this I cannot wait to see the finished product.
Best of luck
