Default Graphic setting to high.
Default graphics settings for this game are too high for should I say lower end systems like mine. Windows 10 Home 64 bit, Intel i5 2500k CPU, GTX 1060 6gb graphics card, 16gb DDR 3 ram. So I ran this game first on a GTX 960 2gb card and had lots of stutter and lockups so I purchased a new GTX 1060 6gb card and still had the stutters and lockups. After going back and forth to Ubi support they ask me for a screenshot of my graphics settings which were set to default for this card and they were set to Ultra. I lowered the setting to high and the stutters and lockups disappeared. From memory, the default settings for the 960 were set too high by default so if I had of lowered them to the lowest setting (you only have 3 choices) the stutters and lockups might have disappeared with that card. Anyway, I was thinking of upgrading my card. Cards are getting so expensive these days. I paid about 3 years ago $350 New Zealand for the 960 2gb card and paid $595 New Zealand for the 1060 6gb card. I'm just posting this in case it helps others with the same issue. :o
