Looking at smoke, from a smoke grenade, causes a big frame drop when FSAA is on. Even though it looks exactly the same when FSAA is off. {F27270} {F27271}

• Throw a smoke.
• Look at it FSAA on 8x and disabled.
Looking at the sea from above also causes same kind of effect with no real visual improvement.
Event Timeline
FSAA is framerate killer, specially on 8x, its not a secret, its a fact. Give us your PC specs. I have high-end machine, but i have low fps with FSAA as well. If you are using 1920 x 1080 using FXAA is just useless.
Well to my knowledge it's not really a framerate killer, as I'm able to use it quite happily with FPS being 55-60 in an empty world. That is until a smoke grenade is thrown or I look the sea from certain angles.
And this is about FSAA and smoke affecting performance, so I really don't see how my specs come into account.
The only thing we are interested in is that if it happens to other people too, or is it just a one off thing.
"If you are using 1920 x 1080 using FXAA is just useless"
FXAA =/= FSAA
OP: I recommend FSAA 4x plus CMAA in post-process antialiasing for better performance while similar quality.
