This did coincide with having another issue where a couple of days prior to subscription renewal my licences stop working and turn orange in iLok manager. It freezes for I'd say no more than a second or two then runs again, a few seconds later it does it again. It will do this when running a track or just moving around the interface and navigating menus. It has started freezing for short periods.
I was running sessions with complete songs happily with no performance problems. It was running pretty well on my PC until yesterday. I'm hoping someone can help me improve the performance of my PT 12.7.1 system. Sorry if this is a long one but here goes.
