I haven't had any CTD since deleting map_height and such. I have fought two battles against the Gauls, a couple against some rebels, and one against the nearby Greeks.
Everything is so much smoother and faster than any other mod I have tried, I bumped everything to its highest setting except AA, and I can play in 1600x900 during battles and the campaign map. I read somewhere script-intensive mods can slow you down a bit, maybe that has something to do with the lag in other mods. (or does this mod just have really efficient scripting?)
I did notice that the Hastati have a red sprite rendered for outside of the FOV, but upon zooming the men are all garbed in light blue, leaving the far end of the line red still (I am aware the visuals are not yet final.)
Wanted the note that the campaign map is totally sweet, and the mini-map is really well done too. The battle ai hasn't shown any deficiency yet, but I have yet to have anything large scale.
So. The CTD isn't universal, and I haven't found anything major in bugs yet.
I will have a proper beta-test report done by this evening.
