Xp vs Vista? Will Vista ever be the winner?

[eyetrip]

It seems like there is pretty much nothing out there where Vista performs better than XP for gaming.

I thought the whole point of DX10 was to improve speeds. DX9 still seems to offer better performance than DX10.

Whats the problem here? Is it that Vista really is a step back in terms of gaming performance? Is it likely that MS will be able to improve this?

Is it a driver/software issue? Are games developers implementing DX10 badly? Or is it the GPU manufacturers not getting out solid drivers?

Just wondering.

Well, thats kind of the thing I don't get about DX10. Its supposed to be faster, yet anything they add as a DX10 only option usually cripples performance.

I don't get the point of that. It eithers offers nothing noticeable, or something noticeable which renders games near unplayable.

Take Crysis for example. I would expect it work work like this:
High settings has exactly exactly the same visual quality on both DX9 and DX10, but DX10 runs better.

Or perhaps I am just not getting the idea of what DX10 is supposed to offer.
