Going into the Windows Color Management, Advanced tab, I found that if I chose either of the "virtual device model profile" choices for the "Device Profile" setting, the performance hit was instant. If I used any of the "normal" icm profiles, performance was good. So I changed my system default Device Profile from "sRGB virtual device model profile" to the std sRGB.icm profile & everything is working great!
