There's a border glitch that is clearly noticeable around his head, legs, and sword hilt during certain lighting conditions. 1920x1080, maxed:
MSAA4x (the glitch is present at 2x and 8x values, as well):
TXAA: (glitchy and also more blurry):
FXAA (border glitch begone, also less jaggies and not too blurry):
Simply put, fxaa is the best option here in terms of looks and performance, especially when combined with downsampling, the results are pretty flawless.
Apologies for posting 3 images in one post, and for all of the overlays and hud elements, I'll post some pretty hudless ACU screenies shortly.
