Epic Games Forums have posted a thread translating an interview with Epic’s Tim Sweeney concerning Unreal Engine 3. Inside you will find interesting technical information regarding Unreal Engine 3 such as multi-core CPU support, DX10 support, lack of AA in DX9 but will support it in DX10, as well as some info that could possibly spell bad times ahead for the Radeon HD 2900 XT in Unreal Tournament 3 compared to the GeForce 8 series.
PCGH: How exactly are you utilizing the functions of Direct X 10? Epic: Unreal Tournament 3 will ship with full DX10 support, with multi-sampling being the biggest visible benefit of the new graphics interface. Additionally, with DX10 under Vista we have the possibility to use the video memory more efficiently, to be able to display textures with a higher grade of detail as it would be possible with the DX9 path of Vista. Most effects of UT3 are more bound to the fillrate than to basic features like geometry processing. That's why DX10 has a great impact on performance, while we mostly forgo the integration of new features.
Of course, we will hold off judgments until we actually play the game, but on paper this bolded comment sure makes us think since ATI has concentrated on geometry performance over texture/fillrate performance with the R600.
