ASUS PB287Q Lag on New Mac Pro

I bought this display based on a couple of positive things I read on here and bought it primarily to hook up to my nMP but I seem to be getting some lag of sorts.

I'm using a Mini DisplayPort to Display Port to connect the monitor to the machine and I've got the DisplayPort Stream set to 1.2 but I still seem to be getting some noticeable lag. 1.2 is a definite improvement over 1.2, but something still feels off. Moving windows around feels slower and less responsive than it feels on my MacBook Air. Even typing feels slightly laggy.

I'm running the Yosemite DP2, incase that has anything to do with it. Really strange, though.

Any help is appreciated. Thanks in advance!

You are probably running at 30Hz.

If you are running the old Mac Pro or if your MacAir has thunderbolt 1, you are locked into the 30hz. On your Mac Pro, I am not sure if a video card upgrade will resolve that issue.

It is a common problem with 4k displays and Macs.

It's definitely 60Hz, when I bring up the monitor's menu it says it's running at "60HZ on 1.2 DP". Not sure why I'm not getting the buttery smoothness I'm used to experiencing on the Mac.
