New rumours have appeared saying that Doom III will be launched on the 3rd of August.
This game is very important for Nvidia since this is where its rendering marchitecture will actually pay off. From NV30 upwards all Nvidia GPUs are able to render texture values without Z or Color information. The NV40, Geforce 6800 series has full 16 pipelines that can process one texture and can render as much as 32 textures without Z or Color info.
This means that in Doom 3, Nvidia's tech is likely to be much faster then ATI's R420. We heard as much as 50 per cent faster but we'll have to wait for the official release and do our own tests to verify that.
