This map is really amazing. And it's a lot of fun. I dont have that much problems about the map.
My only problems are:
It extremely decreases my fps. But not always. Mostly when I'm some of the large locations.
This next problem is my opinion. I think that spawn rates for the vehicles is too high. Like I would find a vehicle right when I spawn and then shortly I would find and a another vehicle. If you can, try to decrease the vehicle spawn rate. My grachips card is GTX 960

Other than that I dont have any problems about the map at all. It is certantly amazing and I had a lot of fun playing it. Keep up your great work. I will get excited when the released version of the map gets released.
