I'd check the hard drive to see if it's gotten full because that's why I've not been able to play TS3 recently and I've got external USB storage to move some of that load off my hard drive though my game itself has never been as slow as yours to load even with thousands of package files of CC and over 800 Mod package files on top of that.I've been playing on my 7 year old laptop with that load in my game and still haven't reached my limit though that can be different for each of us.Buying a portable external hard drive and an AC usb hub with switches to turn the power off on the usb plugs like the one I have can really help if the issue is caused by a full hard drive with not much space left empty.
