D901C : Vista VS XP --- 3d mark and games

Hi all, after weird scores under 3d mark06 under Vista 64 bits i tried to run it with Win XP just to check.

Under Vista i had really different scores from 13100 to 14400....Drivers did not change the problem But everyone told me it was normal so i didnt worry.

But then under XP, BADABOOM lol 15021 and second 15040.....hum seems much better no ?

I have a unbranded Clevo D901C With 9800m GT SLI and a Q9550.

The other thing i noticed under XP with 3d mark06 is the FPS...it is much more constant than with Vista. For example i get 60 fps and almost nothing change in the scene, then VISTA plays like 54/55/58/60/54 when XP will play 59/60/58/60/59 etc etc..

Any idea why ? Im about to try Crysis Warhead under XP

 

Unfortunately this is the way it is with vista You get dx10 and with it some good lighting effects, (hard to see that much difference though) But the performance drops quite a bit..

Microsoft just made a statement that windows 7 will have much better performance numbers. And that it is a OS "revolution" Let's really hope that they are right. Probably not :/

 

Anyway i formatted my hard drive for dual booting so VISTA 64 will still be there if needed....Just need to buy a copy of XP pro if i really use it now i always got OEM before
