Rome wasn't built in a day and neither, it seems, was Rome II.

Total War: Rome II launched on September 3rd to significant outcry about a number of performance and AI issues that were plaguing the game, but this monster patch may have what it takes to get this game running a lot smoother on your setup...

I think Rome II might be the cause of many an unhealthy coffee addiction across the world, as legions of PC gamers look for something to do as they away their turn in their bid for conquest. Creative Assembly have taken aim at this aspect directly with this second patch, improving AI round times as well as a introducing a number of campaign performance optimisations.

Here's the full list of tweaks and fixes for your perusal, deep breath: 

Rome II Patch 2 Campaign Technical and Performance Fixes

Campaign performance optimisations.

Campaign AI round time improvements (greatest effect during early game). 

A new "Limited" option has been added to the "Show AI Player Moves" settings in Single Player and Multiplayer Campaign modes, this enables the player to see all movement of enemy factions, all movement within the players regions, and all movement within sea that the player has ports in during the AI turns.

Improved AI recruitment decisions in Campaign modes. Further improvements planned for subsequent patches.

Pathfinding optimisation on the Campaign Map.

Added earlier Multiplayer Campaign resyncronisation detection, upon loading save games which allows resyncronisation in more cases.

Crash fix for when the player placed the mouse over a garrison force of a region in Campaign mode.

Fix for crash loading save games that were created on the "settlement captured" screen in Campaign modes.

Fix for a crash when holding the [SHIFT] and [CTRL] keys down, and selecting a unit card, when no unit cards where previously selected in Campaign and Battle modes.

Crash fix for when multiple AI reinforcements arrive in a single player siege battle in Campaign mode.

Fix some crashes in multiplayer campaign mode, when one player quit the game, it would cause the other player to crash.

Fix for a very rare crash when launching a new campaign.


Rome II Patch 2 General Technical and Performance Fixes

Fix for "Level of Detail" distances scaling incorrectly when the "Field of View" is changed which reduces the chance of the "Intelligent Zoom" [N] key, causing "zombie like” low quality textures on unit faces in battles.

A new warning message has been added to loading screen to inform the player when graphics memory is running low, and the game is downgrading the players graphics settings. This can be overriden, allowing the game to use system memory for graphics (VRAM) by ticking the "Unlimited video memory" option in the graphics menu.

Increased the frame rate and reduced frame stuttering in battles on certain GPUs.

Improved compatibility for graphics cards with multiple GPUs.

More conservative out-of-the-box graphics settings and resolution for DirectX 10 and 11 on Mobile GPUs.

Some desyncronisations have been fixed in multiplayer city / port assault battles.

Fix for crash when selecting Custom Battle mode after fighting several different Multiplayer battles.

Fix for a crash in 4v4 custom or multiplayer battles caused by the battle AI.

Fix for crash when cancelling a game request for a password protected game whilst in a Multiplayer battle lobby.

Fixed a Multiplayer crash which happened when a client joined a lobby and was being allocated to the wrong slot.

Fixed rare battlefield loading lockup.

Fix for a rare crash caused by animal handlers in battles.

Fix for crash that happens when AI unit triggers raise banner special ability when no human units are selected in battles.

Reduced infantry run speed, charge speed and acceleration in battles.

The low level casualty moral penalties have been significantly reduced in battles.

Improved balancing for Food and Squalor in Campaign Mode.

Campaign AI is more likely to make a stand when defending its final settlement, but may still seek out another home, if they fear losing the final battle.

Encampments battles are no longer incorrectly merged with Coastal battles, which lead to forts floating in the air when a friendly navy reinforced an army in the Fortification stance.

Increased flanking morale penalties.

Added icons to indicate activity in the Technology and Faction screens during a campaign.

Fix for defending armies under AI control grouping together at the edge of their deployment zone, during Ambush battles when the player choses to wait before attacking them.

Improved AI and scripting in the Raphia Historical Battle.

Fixed a bug preventing the player from progressing in The Invasion of Samnium prologue chapter, if they had spent all of their funds before being instructed to recruit a General (and therefore having no funds to do so).

The Attribute increases for an agent accompanying an army now activate its associated effects on the general of that army in Campaign modes.

Improved AI collision detection with Deployables in battle.

In Multiplayer Campaign mode, one player can no longer cancel recruitment during the other players turn.

The order of events leading up to the Battle of Bovianum in the prologue have been re-scripted. The player now gets multiple turns to construct siege equipment.

Fixed issues with not enough time being given for certain advisor lines to play in different languages in the prologue.

Fix for units floating in the air while climbing siege towers in battle, when the tower is placed on a slope.

Attacking siege ladders will no longer clip through the gate house in the siege on Bovianum battle during The Invasion of Samnium chapter in Prologue Campaign.

The victory screen in Multiplayer Campaign mode now shows the correct title for both players.

What issues have you been having with the game, and does this seem to fix any of them?

Or they should have beta tested it.
For some profound reason CA does not believe in beta testing.

01:40 Sep-18-2013

This patch contains so much stuff, it should have actually been the official release patch :S

I forgive them for rushing.
I don't forgive them for not making it SLI supported. Especially in this day and age.

16:05 Sep-19-2013

Crossfire is only possible because AMD made it possible, not CA.
Nvidia isn't doing anything about it.

20:20 Nov-19-2013

do you know how many games are optimized just for nvidia? What about all the AMD users out there? I understand that Nvidia is the bigger GPU company but still.
