Try downloading the Stream Memory Fix, Maybe that will help.

I'd say the S3.

I like this alot... Very good work, Keep it up! And a little suggestion as Wennicke made you may want to remove some helicopter pads ^^ Overall great.

Awesome, Just the ability to customize your house and build it how you want is brilliant.

Nice ^^ As stated in a few comments before, Few more objects to fill the gaps and maybe a little car park area defined with some bushes would be great. Other than that it's a brilliant map.

Los Santos, I just think it has all the different types of area in one city, Ghetto... Industrial and High Class, All types in one city. Best city for Role-Play in my opinion.
