Presumably because most (all? I didn't check) of the geometry is stored in display lists. These can be stored on-card and eliminate the need for per-frame vertex transfers across the AGP bus. In modern hardware bus bandwidth, and not processing power is the primary limitter of 3D performance. It's worth pointing out for Linux (and BSD) folks, though, that the DRI drivers for the Radeon don't yet support the on-card GPU. All vertex transformations are still done in the CPU; the graphics hardware is used for texturing only. Hopefully this will change soon. Andy -- Andrew J.
