Today, Ubisoft launched a new patch for the PC version of Assasin’s Creed. The patch will fix a couple of bugs in the game, among which the bug where Alt-Tab key combination would crash the game. The patch will also introduce post-effects improvements for cards with DX10.1 support and add support for x64 versions of Windows.

The thing that Ubisoft doesn't really say is that this patch removes the support for DirectX 10.1, and it causes up to 20 percent performance drop for all Radeon 38x0. Since Assasin’s Creed is Nvidia's The Way its Meant to be Played title as per Nvidia's request, the game somehow lost its ability to run better with DirextX 10.1.

It's one thing to choose not to support a feature such as DirectX 10.1 but removing it from the title that obviiously scores better on competitors' cards is immature and despicable, to say the least.  

In case you don't own a on 38x0 card, you can download the patch here and the complete list of fixes is as follows:

- Fixed a rare crash while riding the horse in Kingdom

- Fixed a corruption of Altair's robe on certain graphics hardware

- Cursor is now centered when accessing the Map

- Fixed a few problems with Alt-Tab

- Fixed a graphical bug in the final fight

- Fixed a few graphical problems with dead bodies

- Fixed pixellation with post-FX enabled on certain graphics hardware

- Fixed a small bug in the DNA Menu that would cause the image to disappear if the arrow was clicked rapidly

- Fixed some graphical corruption in Present Room with low Level Of Detail

- Character input is now cancelled if the controller is unplugged while moving

- Added support for x64 versions of Windows

- Fixed broken post-effects on DirectX 10.1 enabled cards

As you can see, Ubisoft, a publisher that likes to cow Nvidia for TWIMTBPlayed titles, comments on this issue as "Fixed broken post-effects on DirectX 10.1-enabled cards. " Good job, Nvidia and Ubisoft, for making a really big issue and losing face in front of millions.
