Lately I have been playing the mod with the 1.87 opt. It is the beta from the next patch where things as the LAA are integrated in the game.
As you can see, I am playing one of the largest maps. More of 40 minutes without crashes. Equal than playing the 1.86, in fact the last 1.6 is better than this because it has compiled all files and it loads faster than my in development 1.7.
I will continue the battle later.
