The Total War Wiki has the detailed patch notes on a third patch that's now live in Total War: ROME II with over 140 technical, gameplay, balancing and usability improvements. Creative Assembly also states that Patch 4 will enter public beta "soon," and will offer "further technical optimizations and improvements to gameplay, balance and usability." Here's the short version of what's new: "Technical optimizations include Campaign performance improvements on some hardware configurations, fixes for UI flickering in SLI setups, and a significant multiplayer campaign-speed boost. There are many new gameplay improvements, such as alterations to the victory point system, and chiefly a reduction in the circumstances in which victory points appear in battles. For example, when the player is attacked while occupying a minor settlement (though not a provincial capital), a new Sally Forth button is available on the pre-battle panel, which enables the player’s army to fight the attackers in an open field battle without victory points."
