If I put every setting at maximum quality, I get just 9-11fps (and ultra lag, of course). I think I should be able to play everything at maximum quality at 1080p with two GTX 770.

If I change resolution scale from 200 to 115 I can play smoothly, but with 28-40fps.

Is that normal? Nvidia's control panel and GPU-Z recognize both cards in SLI, so the problem isn't a bad installation.

What is your system's native resolution? If it's 1920x1080, what you're doing by setting 200% Resolution scale is doubling the resolution in game. If you're already at, say 1440p, you're up and over 4k res when at 200% scale. I would definitely leave that at 100% and just use AntiAliasing instead. And by maximum, you're running nearly 4k (if at 1080p at 200% scale) AAx8, AFx16, and V-Sync most likely. Turn V-Sync off, set resolution to just 100%, and set AA to x2 or x4, as x8 would only be noticeable at very high resolutions AFAIC. If you had 4 780Ti's I can see 3 monitors at the settings you just tried, maybe. Overkill and unnecessary, though.

If you want the x8 AA with good FPS, though. You should be able to dedicate one of...

If you want the x8 AA with good FPS, though. You should be able to dedicate one of your 770's to handle Anti Aliasing on it's own, and the other for the rest. Like Malaki said, a single 770 can crush BF4. Use the other 770 however you'd like. :)

Thank you The Letter Mu, with resolution scale at 100 and the rest at maximum quality posible, there is no lag at all. However, I supposed 2 770s could play smoothly at 4K. Perhaps a new driver makes that possible, as with just one 770 you get just a Little less fps than with 2.

~Unfortunately not no card at the moment can truly run 4K bar Titans in SLI even then it's barely able to pull Medium in BS:Infinite
