After the Ostara recent install I have just in the last few days noticed an annoying stutter and the load icon appears. My game was fine I have played around with graphics setting. My deduction is that it is in the software, recent. I can not reinstall the whole 127 Gb again.
As I said, I believe it is a recent software issue. Look at history and see what the fixes were for earlier issues of this nature
Also a recent corrupt save data kept popping up and therefore was pointless playing. I read other posts and they didn't help
Please please just fix your software and please stop making us go through all these suggested hoops, when deduction shows its most likely changes that have been made on Ubisofts end

I can not play because any attempt to save a game, reload or reboot makes no difference. Seemed to start after latest Ostara festival
Its not divers, its not the system, its Ubisoft.
This is getting very frustrating
Would like to see Ubisoft fix this soon, without offering the usual mucking around options for the users to try
Obvious when your systems doesn't change and it worked before then this issues come from Ubisoft
