not really
TAA has 2 modes
TAAx2 or TAAx3
these multiply the normal FSAA modes of 2, 4 or 6
for instance TAAx2 and FSAAx2 makes the AA look like x4, but it still performs like x2, which is great.
how it works is clever, but you need vsync on, and a fps over 60 (60 is too low i think, 70 works slightly better). Anyway, it starts by alternating the AA angle, so Angle A, and angle B go like this ABABABABABABA....TAAx3 would be ABCABCABCABCABC. The reason you need high fps and vsync on is because of the rapid flicking of the different AA angles. if using TAAx2 (ABABA...) @ only 60fps, you get 30fps of A's and 30fps of B's, but because its only 30fps you will see the rapid changing of pixels on the edge of objects, and it looks like your gfx card is broken! lol
TAAx3 makes this even worse, as at 60fps /3 = 20fps.
70fps min if you want to use TAAx2 and not see *much* flickering (i still see Some if i look for it, barly noticeable), 80+ would be better. TAAx3 needs about 120fps/hz to work without the flicker
the rapid flicking of different angles trick your eyes into thinking your using the higher FSAA mode, but the gfx card does less work
