Should be relevant to GoW PC as well. From 5/31, but hey, it's a German interview.

PCGH: You rescheduled the game to Q3 in 2007. Was one of the reasons behind this that you had to do some technical changes with the engine or that you found ways to improve your game technology?

Tim Sweeney: We didn't reschedule anything. UT3 has always been about being done when it's done. We're taking our time with the game because the UT franchise is very important to us and we want to get it right for this, the third generation in the series.

PCGH: You are using deferred shading. Will there be any chance to get FSAA working with DX9-Level-cards? What about DX10-cards?

Tim Sweeney: Unreal Engine 3 uses deferred shading to accelerate dynamic lighting and shadowing. Integrating this feature with multisampling requires lower-level control over FSAA than the DirectX9 API provides. In Gears of War on Xbox 360, we implemented multisampling using the platform's extended MSAA features. On PC, the solution is to support multisampling only on DirectX 10.

PCGH: Can you at this point of development tell our readers what kind of hardware will be required to play the game with all detail in 1024x768 (No FSAA/AF) and 1.600x1.200 (with 4xFSAA - if available - and 8:1 AF)? Will there be any fallback modes for gamers with older hardware like Shader 2.0 cards?

Tim Sweeney: Optimization is still ongoing, so these numbers change on a daily basis. In general, our Unreal Engine 3 games run quite well on DirectX9 class hardware that NVidia and ATI released in 2006 and later, and amazingly well on the high-end cards including DirectX 10 cards. We also support Shader Model 2.0 hardware with minimal visual difference.
