UPDATE:

Ubisoft has a new forum post regarding the ongoing issues with Assassin's Creed Unity on PC:

"As previously reported on the Assassin’s Creed Live Updates Blog, our team is furiously working to resolve bugs and performance issues for Assassin’s Creed Unity on all platforms. On PC, some media outlets have misinterpreted a forum post indicating that we were working on resolving issues that were AMD-specific. We apologize for any confusion and want to be clear that we are working with all of our hardware partners to address known issues that exist across various PC configurations. We care deeply about a smooth and enjoyable Assassin’s Creed experience and we will continue to update customers as these issues are fixed via the AC Live Updates Blog."

Several users have reported technical issues with Assasin's Creed Unity on PC. 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."The developer has also invited people who have experienced issues to contact them as they continue to work out the bugs and problems.IGN's official review of Assassin's Creed Unity called it a "successful proof of concept" that doesn't quite do anything revolutionary.
