Assassin’s Creed DX10 Faster Than DX9

Speaking with Charles Beauchemin, technical lead on the PC version of Assassin’s Creed, PCGH reveals that the game will be available in both DX10 and DX9 variants, with the former being faster on Windows Vista. Here’s the scoop:

PCGH: How much of a performance hit will the improved optics of DX 10 incur? With all details maxed out is a typical first gen DX 10 card already running at its limits?

Charles Beauchemin: No performance hit occurs, since no improved optics are implemented. However, when running on Vista, DirectX 10 version speed will be much faster than its DirectX 9 counterpart (also running on Vista).

He also points out that there will be no graphical improvements in the DX10 version, adding to its speed. However, real benchmarks are yet to be performed, so none can say if his claims are true. We will find out soon though, as the game will be released in a few weeks.
