The Total War forum has the promised release of a new beta patch for Total War: ROME II, along with word on the status of the next official patch for Creative Assembly's strategy sequel:

We have taken the decision to move back Patch 2 slightly to increase the amount of fixes included in it. We will have more news on it later this week.

Before then, Patch 1.5 will release which contains one important fix.

Patch 1.5 will enter public BETA testing today. It will not automatically update your game at this time, you can download it should you wish to participate in the BETA test by following the instructions below:

Patch 1.5 Contains one fix: - Should improve Campaign Map frame rate in the majority of cases for those people with high-end graphics cards combined with mid-range CPUs. Those people who have noted high frame rates in battle but single-figure frame rates during Campaign Map play should see a notable increase in performance.
