SEGA and Creative Assembly have released the ninth update for Total War: Rome II. This update comes with performance and memory optimisations in Campaign modes, improved framerates when units clash in battles, as well as battle AI and behavioural improvements. You can view the complete changelog below.
Total War: Rome II Patch #9 Changelog:
Technical and performance improvements:
- Performance and memory optimisations in Campaign modes.
- Further work to reduce the CPU costs during battles.
- Improved framerates when units clash in battles.
- Siege battle performance optimisations.
- Eliminated several rare crashes found in battle scenarios.
- Fix for rare crash related to naval boarding/disembarking
- Multiplayer battle-replay desync addressed.
- Issues with trees in battle-maps addressed.
- Additional cost-balancing to Chariots and Elephants.
- Units no longer mistake bastions for wall breaches in settlement battles.

Support for AMD switchable graphics:
- Game now correctly detects and reports the discrete GPU on an AMD switchable graphics configuration (primarily laptops with an Intel integrated GPU and a discrete AMD mobility GPU).
- This fix ensures that the ‘unlimited video memory’ graphics option is enabled correctly on AMD switchable configs.
- Note that the Catalyst Control Centre Switchable Graphics UI must be used to select between the discrete and integrated GPUs for each application that the player wants to run.
Support for ‘Virtu MVP’ Desktop Switchable Graphics:
- Virtu MVP is a common OEM-installed application for selecting GPUs in a multi-GPU desktop configuration e.g. a desktop with an Intel integrated GPU and a discrete desktop GPU – both typically routed to the same motherboard display output connector.
- We now correctly detect and report the correct GPU used in this scenario.
- Note that the Virtu MVP Control Panel application must be used to select between the discrete and integrated GPUs for each application that the player wants to run.
- New option in the Advanced Graphics Settings menu, for selecting between graphics cards / GPUs when more than 1 is available.
Support for multi-GPUs with multi-monitor configurations:
- Game now detects multiple GPUs and allows the player to pick which GPU is used to render the game.
- In this configuration multiple GPUs are shown in a combo-box in the Advanced Graphics Options UI.
- Improved video-memory detection to prevent the game from sometimes detecting the video memory limit from the wrong/lower graphics card in a multi-GPU configuration.
Battle AI and behavioural improvements:
- Improved pathfinding of siege vehicles near walls.
- Improved multiple siege ladder functionality parameters.
- Improved siege vehicle docking placement.
- Units now consistently disembark from ships with raised bows.
- Improved AI infantry awareness of cavalry, making infantry brace when threatened by a charge.
- AI controlled units are now more likely to use flaming arrows against elephants where available.
- Improved logic of multiple battle maps, to allow the AI to interact with these maps better and cause fewer behavioural issues.
- Improved AI General’s use of special abilities.
- Rebalanced AI’s battle-plan analyser/attack-or-defend decision making, to take into account that the enemy alliance may have weaker but longer-range missile units, to prevent static behaviour under missile fire.
- In ambush battles, the defender’s units which are under missile fire that outranges their own are now more likely to respond by moving to intercept the missile unit attacking them.
- Altered some of the AI’s usage of various ammo types.
- Pike Phalanx now reform properly once engaged in melee.
- Idle units attacked when set to Formed Attack attempt to keep their current facing.
- Formed attack charges will now penetrate less than free attack barbarian charges.

- Routing units no longer turn around/play matched combat animations as they are being killed.
- Units now no longer head through breach in a wall rather than using the siege engine they are attached to.

- Men positioned on a gatehouse will no longer die when the gate is destroyed.

- When dog handlers unleash their dogs, the handlers will no longer attack as well.
- Added blood to chariot horses and drivers, and to attackers and defenders during knockdowns. (Only active if the player owns the Blood and Gore DLC.)
- Artillery on ships can no longer be picked up (previously resulted in loss of unit control).
- Improved unit reforming on the battlefield.
- Projectiles no longer remain in mid-air when the siege weapon that fired them is destroyed.

Smaller defensive bonus in minor settlement battles
A small global penalty for the player in autoresolved battles
Unit threshold has been increased, so severely damaged units are less likely to survive an auto-resolved battle.
