Topic on Talk:Assassin's Creed Unity
I did some experimenting with AC Unity's antialiasing settings and, to my surprise, the game's usage of FXAA is actually capable of mitigating subpixel aliasing (mainly the breaking up of distant thin geometric objects, such as ropes) to a degree. Not to the extent that MSAA and TXAA can, but still. I personally was unaware FXAA could even do that.
A couple images (zoomed in at 600% then cropped) for proof:

Figured it was worth mentioning.
