I just got a Lenovo Y50 (4K Touch edition) and I installed Minecraft (and Feed the Beast) both are having the same problem: my mouse cursor is updating and moving perfectly, but when I hover over a menu button or jump in game there is a delay of about .25 sec for the game to catch up to my actions.
In the Feed the Beast Launcher I checked the optimization arguments box and turned up the maximum RAM usage to 8GB (it used 3GB on Infinity mod-pack). The game ran fine that time but I started Feed the Beast again with no changes and it was having input lag again.
I have been turning up all of the performance settings on my computer and nothing is helping. I also tried disabling the touch screen.
Just figured out that the problem only happens when the window is maximized. Probably because of the resolution. But I decreased my display resolution and it was still slow. I guess I need better graphics capabilities.

If anyone has any suggestions please reply.
If you have a very high mouse sensitivity, I believe this can happen. Have you tried turning down mouse sensitivity?

A few of my suggestions and a personal favorite suggestions. More neat-o suggestions in my bio.
Yes, I typically play with a low sensitivity. But the problem is in the menu and game with the keyboard as well.

I fixed the problem. PhysX was reserving most of my GPU so I rerouted it to my CPU and It's working.
