Groove Agent 5 more CPU hungry than SE 5

I have upgraded from Groove Agent 5 SE to Groove Agent 5 and I am finding that for exactly the same instruments and set up, Groove Agent 5 causes a much bigger CPU load and as a result is causing glitching.

I now use Groove Agent 5 SE during recordings and then freeze everything and switch to Groove Agent 5 when mixing down and refining beats.

Has anyone else had this issue and come up with a better work-around?
