Assassin's Creed - First DX10.1 Title?

@ 2008/04/18

The impact that DX10.1 has is quite frankly greater than expected. A 20% improvement in AA performance is very impressive. GPU refreshes have been built around lesser gains. Based on the game's behavior it's possible that Ubi are doing their own Custom Resolve in order to get HDR correct AA, and are also taking advantage of the full access to MSAA buffers DX10.1 brings in order to get both better quality and better performance, but without an official statement we'd rather refrain from speculating further.

Having me here basically means that I’ll be giving you updates on what’s going on with Assassin’s Creed and the first bit of news I have is that we’re planning to release a patch for the PC version of Assassin’s Creed that addresses the majority of issues reported by fans. In addition to addressing reported glitches, the patch will remove support for DX10.1, since we need to rework its implementation. The performance gains seen by players who are currently playing Assassin’s Creed with a DX10.1 graphics card are in large part due to the fact that our implementation removes a render pass during post-effect which is costly.

so far for the DX10.1 performance boost.

Now put XP DX9 render path performance next to it; would be interesting
