Got another update on the Unreal Technology page following the release of DirectX7 yesterday. Looks like the D3D version of the demo is currently in final testing as we had all hoped/expected. Check it G:

Now that DirectX7 is available, we're doing final testing and tweaking on the upcoming Unreal Tournament demo with Direct3D and OpenGL support, coming in the next few days. One thing we've found on DirectX7 is that NVidia TNT2 performance is not fill-rate limited until you get to very high resolutions.  During testing, performance at 640x480 seemed a bit slow, but as we increased the resolution, the frame rate was hardly impacted at all.  So 1024x768 seems to yield the best overall experience on this card. I've enabled support for 32-bit color textures under Direct3D, which significantly improve the graphical quality, with a 10-15% frame rate impact.The Direct3D code now uses vertex buffers, which speeds up mesh and text drawing a bit
