It's a huge oversight in the game's optimization, and I'm guessing it's impossible to fix easily for CA considering how it's never been fixed through the game's many patches. There is pretty much nothing you can do about this. The larger the yellow 'circle', the worse the lag.

This is because, I expect, the game repeatedly calculates all possible paths your army can take in order to create that yellow area on the game map to show you where it can move in one turn. On the campaign map, when you click on an army you're gonna get a noticable decrease in FPS. Turn AA off, and force it through nvidia's control panel if you really want it. AMD's FX-series do not excel at single-core processing like Intel's stuff from the same generation, which really hinders the performance of Rome II and Attila. You have to do this every time you start up the game, but it helps a bit. Since Rome 2 uses one core for most of its processes, it's better not to use the same one your OS uses for most of its background stuff. 'Set Affinity' and uncheck 'core 0' or whatever the primary core is numbered as. Things to help you out/to recognize with Rome's performance:Īfter starting the game, open the Task manager, go to 'details' and right click on the Rome 2. Piledriver CPU's just don't run Total War games very well. You can get some performance increase by setting your affinity to prevent the program from using Core 0 through the Task Manager, but even then the performance is gonna be sub-par. Warhammer I and Thrones of Britannia are the only games that are optimized well enough to not lag hard, but even then the game isn't using the full capabilities of my PC. I run with a FX8350, and I can say - after hours of playtime - the CPU is definitely the bottleneck for you.
