I tried it with a UI reset and after a repair, the only thing I haven’t tried is a full reinstall. I even posted my task manager graphs in the Tech support forums post, it’s not my graphics card or my processors. They are not overloaded. I recently set my windows back to new install on another PC and it did the same thing. I think I’ll try a full reinstall tonight. Firstly without any addons then with.
At least the repair fixed my profession window lag.
