Performance Pr CC vs Pr CC 2014

I have been trying to migrate over from Pr CC to Pr CC 2014.

The first thing I noticed is that fast forward and fast reverse are very choppy on Pr CC 2014 and much smoother on Pr CC.

It is so choppy that I will not use it.

I am making the assumption that I will need to upgrade my system to use  Pr CC 2014

I have just updated  Pr CC 2014 - 8.1.0 (81) Build and the GPU drivers.
