I posted an entry down in the thread Battlefield 2 poo performance
On an X1900XTX, I'm seeing slower performance under Vista than I am under
XP. Some of the performance drops are Major (like 30% in HL2 and FEAR) other
performances are only a few hundred points in benchmarks like 3dMark05 and
06.
I'm of course, still tweaking with my system, so maybe I'll find something
that ups\helps the performance at some point, but right now, Vista in
general and the beta drivers from both Nvidia and ATI are probably not very
polished and probably won't get the same level of attention as XP until
around new years, ot a few months before Vista is actually going to be
released.
I've included my numbers from the other posts for your viewing pleasure.
Here's a list of benchmarks I've ran so far with the X1900XTX, using the
beta Vista drivers from ATI and Vista RC1 (build 5600).

Under Battlefield 2, the performance seemed fine at first, but as I starting
playing, I noticed alot of stuttering and drops from a normal steady 99-100
fps to 50 fps.
