Thats more technical on the side of optimization, I believe we were both referring to gameplay mechanics within the engine upgrades. Does the melee combat still suffer from the same issues of Rome 2/ATW where they all just blob and none of the units have a mass characteristic in battle.
As far as technically optimizations go, well one would hope that the engine received various performance enhancing elements, ATW and Rome 2 were very very rough performance wise on decent PCs because they catered to the low spec consumers out there and it cratered high end users with really unfortunate bottlenecks.
