As many of you may have noticed, Rome II's in-game "anti-aliasing" option is a simple on/off toggle switch that turns on what is called "FXAA", or Fast Approximation Anti Aliasing (or it could be "MLAA", Morphological Anti-Aliasing, but they're both almost identical). Anti-aliasing in general is meant to "smooth out" the "jaggedness" of textures. The benefits of FXAA over conventional/normal anti-aliasing is that it is pretty much zero performance hit. The drawback, however, is that it is really just a post-processing blur filter that makes the game look muddy and washed out.
So basically Rome II players are forced between making their game look jagged and awful*, or blurry and awful. I give you a third option: SweetFX. Download this (http://forums.guru3d.com/showpost.php?p=4581604&postcount=528
) and drop it in the folder "Total War Rome II" (which should be in your Steam > Steamapps > Common folder). After doing this, open "SweetFX_settings.txt" in Notepad and make sure "SMAA" is set to 1. Also fiddle with anything else that that you'd like but personally I only use it for SMAA. Then start the game and turn off the in-game anti aliasing in the options, and hit your Scroll Lock key (should be near your Print Screen and Pause Break keys) to toggle SMAA on and off. I recommend starting a battle first and zooming in on a group of soldiers for the best comparison.
SMAA, or Enhanced Subpixel Morphological Antialiasing, is basically yet another post-processing anti-aliasing function, except it looks much
better and contributes nearly zero blur.
A few people have probably already suggested this, but I because the game just released that the signal-to-noise ratio on this forum might have drowned them out, so I'm making my own thread.
* = It may be possible to force conventional multisample/supersample anti aliasing, but given that Rome II already pushes my system right up to the limit, and I'm on a fairly modern system (3770 i7, 8GB DDR3, 660Ti OC'd), I doubt many people are looking to lop their already low framerate straight in half.
