Quote: "DX9 and DX10 could just be switched between themselves with no slowdown. They are just basically different addresses in the computers memory. One folder could contain DX9 and another could contain DX10. Dll's are shared anyway so just give the DX10 dll's new names."
Ok let me try re-phrasing this a bit - DX10 will drive the entire look of Vista. Every button, every window, every icon, every drop-down menu, every input, sound, etc. Are we getting the bigger picture yet? Do you honestly believe you will be able to just rename some core system DLLs and have DX9 back again?!

Riiiight. Damn it, of course it's that simple. Just remove Aero and.. whoah, shit.. where's everything gone? Oh that's right, I removed the GUI from Windows.
Please, come on, use the common sense you were all born with?
Another thing worth considering is the system requirements of Vista.. they're huge if you want it to run well, so even if DX9 emulation is 20% slower I'd be surprised if you notice it unless you're running on the same old hardware. Vista is going to require a PC upgrade for loads of people, me included - I'm not putting it anywhere near my PC, and it's not that bad a rig, but without a processor upgrade to something either natively 64-bit or dual-core, forget it. It might run, but it won't be the way its intended.
