Q. Does Unreal Tournament 3 take advantage of over 512MB of video memory?
A. We're going to significant lengths to take advantage of 512MB video cards and PCs with lots of memory. On PC, we're shipping lots of 2048x2048 textures, a higher resolution than we can support pervasively on console platforms. However, PCs running 32-bit Windows XP or Vista run up against a glass ceiling pretty quickly above 512MB of video memory. Because of the way the OS maps video memory into the 32- bit address space, going beyond 512MB doesn't really increase the overall usable memory. Thus, we're not focusing on exploiting more than 512MB video cards.
That situation will change over the next few years as Windows Vista 64-bit adoption takes off, because the 64-bit OS eliminates the address space bottlenecks and enables video cards to scale way up in usable video memory. But, if you look at the latest data on what gamers are actually using, e.g. with Valve's excellent survey of gamer hardware ( http://www.steampowered.com/status/survey.html), it's clear that 64-bit Vista isn't taking off yet. Give the industry a couple years, and this will change.
