And though this is a console port, Ubisoft blames AMD for the technical issues in Assassins Creed Unity. Kinda weird since all the consoles run an AMD APU eh ? AMD Radeon users report texture issues, low frame rates and overall glitching problems. Ubisoft claims the issues are related to select AMD CPU and GPU combinations, which points to a lack of testing on AMD hardware. So all of the sudden its AMD's fault ...
The main root cause of the issue isn't AMD or for that matter Nvidia who's mid-range products run into issues as well, it's Ubisoft. The DX11 game currently is pushing roughly 50,000 draw calls on the DirectX 11 API. DX11 is designed to handle ~10,000 peak draw calls. Mantle and DirectX 12 are designed to handle that number, but not DX11.
Ubisoft just started responding to this on their forums:
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. 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.
Really Ubisoft ? Next time spend some quality control on AMD Graphics cards with your multi-million investment ?? Simply put its once again a bad port for the PC Platform that is not rather well optimized title.
