Tim Sweeney heeft weer een update gepost op de Unreal Tech page. De Unreal Tournament Direct3D/OpenGL demo bevindt zich op dit moment in terminaal test stadium. Wie had gehoopt op een snelle release lijkt bedrogen uit te komen, want het lijkt erop dat we nog enkele dagen moeten wachten :
Microsoft has released DirectX7. You can read about it and download it from Microsoft's DirectX Page and download it on their Download Page.
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.
What about OpenGL?
We're still maintaining OpenGL sypport, though it's not as much of a priority at the moment because texture management performance in GL on Windows is significantly behind Direct3D. It's still useful in NT4 and Linux of course. I've been advocating a GL extension which would enable the fine-grained control over texture management that has led to such an improvement in Unreal performance under Direct3D.
