No problem here, very, very slightly slower but I am normally working offline, when I do go online to check for updates etc and try it there then it does really slow down, particularly if I tried to use a Cloud Library which I have now dumped as I have no need of it now that I have only a single location to work at these days.
IMHO if you don`t need to use the Cloud (Bunch of servers flying in a loose formation!!) for remote access by either yourself or others involved in your work then leave it be 🙂
As long as you have a reasonable specification computer at your location then as I have found it is faster/easier to stay offline, no reliance on slowed down Internet/Autodesk Servers at peak times 🙂 🙂
FYI My computer that was pretty cutting edge when it was built for me is now 11 years old and is just about managing, I have even got it working on Win10 although the Motherboard says the OP isn`t compatible and can no longer be updated it does still run 🙂 🙂
I have to go online more these days as we are now in the position of not being able open files made with the next Version, gone the same way as all the other Cad-CAM softwares in that regard, but, hey, that`s progress isn`t it ??? 🙂 🙂 🙂
