Aside from the widespread issues affecting the console versions of Assassin's Creed: Unity, the PC version is also being hit by apparent performance concerns.
Ubisoft has said that those running either an AMD processor and graphics card are having trouble sustaining decent framerates at decent settings. There have also been reports of lag, crashing and freezes.
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,” the publisher said on its forums.
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.”
It's worth noting that some Nvidia GPU owners have also bemoaned the performance of the game. The general consensus is that it's more dependent on a user's CPU than a GPU, so those with high-end Intel processors are apparently getting better results.
There has been much in the way of bad news for AMD CPU owners in recent months. There was a time ahead of the release of PS4 and Xbox One when some were arguing that AMD's multi-core CPUs, which closely mirror the architecture of both consoles, would provide better results for multiplatform titles.
This was an especially appealing narrative as AMD's CPUs are considerably cheaper than their Intel equivalents.
However, what we've seen is that the vast majority of recent releases continue to offer far better performance on Intel chips.
