Re: Building GTA size map: Possible?
I've played some pretty huge 3rd party maps in counter strike source, so big that even though I'm on max settings I cannot see the other end of it and it runs smooth with 64 players.
The biggest I've played is a part of a city that has jail, where the terrorists start, and two bomb sites one is an apartment building and the other is a bank. I guess it runs smooth, because you cannot enter the majority of the buildings.
Still there are so many different routes you can take between the many buildings and their back alleys etc.
