The 30% CPU load is at idle. So when other programs are also running (Hero Lab, Chrome, etc.) along with D20Pro, then the load is higher and simple things like moving a character on the map can make things spike to over 100%. That is what make game play slow. I don't know if that is related to our connection issues or not. But ever since D20Pro version 3.6.x and up, we have had slow game play and bad connectivity.
