BeyondUnreal has conducted an interview with Tim Sweeney of Epic Games, as he talks about Epic's new Unreal Engine 3. Here is a taster:
BU: UT2004 required 5.5 gigs of hard drive space to install. This has got to be a strain a lot of people's systems. So you're talking 2048 x 2048 texture sets, what kind of system and memory is this next game going to take?

TS: Well, we are aiming at the kind of PC that we think will be mainstream in 2006. We will also be able to scale it down. Basically DirectX 9 cards will be minimum spec, so any DirectX 9 shipping today will be capable of running our game, but probably at reduced detail. If you only have a 256 meg video card you will be running the game one step down, whereas if you have a video card with a gig of memory then you'll be able to see the game at full detail.
