noob question

[attra]

This goes pretty off-topic but I write it anyways:

For me, on Vista: Games lag on lower graphics.
On XP: I put everything maxed out and they work lot better without any lag at all (or very very little).

For example I once downloaded Crysis demo to see how powerful my computer is.

Here is the result:

Vista: Everything at High no AA. FPS = 10-20
XP: Everything at High 8x AA FPS = 20-30

And this is not the only game. Every game that I've tried on both works smoother on my XP.

I like Vista because it's beautiful, but I play my games on XP.

cool well overture runs fine i can not see how i would have any issues with black plauge and requium
thanks for the help

oh and FYI run crysis in dx 9 settings on vista and it runs fine
