HARDOCP has a tip for playing Battlefield 4 on Windows they came up with
while putting the military shooter sequel through its paces for their technical
evaluation. They encountered some odd results in the game's antialiasing, and
have this preliminary tip for users looking to improve the game's visuals:
We are hard at work testing BF4, and the first thing we discovered was
that the textures did not seem up to par for a new Frostbite 3 engine game. We
quickly found out that by turning the "Antialiasing Post" (inherently FXAA)
graphics setting to "Off," fixed this problem. The textures were now much
sharper, clearer, and the fidelity in the entire game was better.
Post AA seems to be adding blur over the entire image, even though it does
reduce aliasing on everything. It is the nature of FXAA, but it seems apparently
bad in BF4 according to our testing so far. You have an interesting choice. We
have a poll and a discussion thread which we would love to hear your feedback on
what settings you prefer while you play BF4.
