I got a chuckle this morning when I installed the Worldwide Telescope app.
Why? When you install it on a Vista machine you have to install DirectX 9. Thing is that Vista already comes with DirectX 10. So think about this: To get the richest interaction in a showcase app like WWT, you have to “downgrade” your graphics library. All I can say is: Make up your mind. Is DirectX 9 or 10 the state of the art?
If DirectX 9 makes sense in a topnotch app like WWT, then DirectX 9 should be in Vista.
Don’t get me wrong, as a developer I understand and appreciate what’s going on here. It’s just that during this transition period, it’s worthwhile to keep the spotlight on issues like this, so that things don’t get worse.
