Users on Steam claim the PC version is poorly optimized and suffers from a wide range of problems, including poor frame rate, crashing, clipping, mouse lag on menus, freezing, poor rendering, and a general lack of graphics options.
Ubisoft has commented on the problems, noting that they seem to effect AMD users especially.
"We are aware that the graphics performance of Assassin’s Creed Unity on PC may be adversely affected by certain AMD CPU and GPU configurations," Ubisoft said on their forum. "This should not affect the vast majority of PC players, but rest assured that AMD and Ubisoft are continuing to work together closely to resolve the issue, and will provide more information as soon as it is available."
