How does 200% resolution scaling work?

[Aleksandar M]

Hello,
I would like to know how 200% resolution scale works in BF4, so that I can consider multi-monitor or 4k set up in the future. My understanding is that if I run the game at 1080p it will be ran at 3840*2160, which is like 4 1080p monitors then downscaled. Does this mean that if I buy a 4k monitor and use 100% res. scale I will get the same fps as 200% @ 1080p? Also can I get 4 monitors and run them at 100% res. scale and get the same fps?
Thanks

In general the performance should be similar for sure.

You may have a bit more overhead with the 4 monitor setup, but it should not be that big.

That kind of resolution scaling will kill any single cards performance.

So 4 1080p monitors would perform better... I get around 45fps on ultra 1080p with 200% scaling with 7870tahiti and 7950 CF.

No 4 1080p may actually have a bit more overhead(not sure exactly how much performance hit it would cause however.).

That's not half bad.

My single 670 would roll over and die.
