Running Naval Action at 1920x1080 with everything on Ultra, runs around 60+fps
No issues here with AA turned off, FXAA, as OlavDeng2 mentioned makes it look, a bit blurry, nicer but blurrier, and well overall works a tad better then AA.
In general at 1920x1080, AA is rather... meh useless (at maximum just use 2x, higher than that might not give any effect, since it all depends on how the game/engine is)
