Quake 3 / Vista

> Hello,
>
> I encountered a problem in gaming experience while using Windows Vista
> Ulitmate 32bit.
> I noticed a framedrop of more then 200 fps, this framedrop can be reduced by
> setting the graphics lower.
> My default settings on winxp for this game are: 1280x1024 32bit (quality
> settings maximum).
> On Windows XP Pro i will get over 250 fps. (since no more is allowed, capped
> at 250).
> On windows Vista Ultimate with exactly the same settings i will get about 50
> fps.
>
> Specs:
> AMD Athlon(tm) 64 Processor 3200+ (2.20 GHZ)
> 1023 RAM
> Radeon x800 GTO

> Question:
> 1. Is Microsoft aware of this problem?
> Since this will not be the only O.S/Game problem yet to come.
>
> 2. Am i correct when i say this is not mainly Microsoft but Radeons problem?
> Since MS is not responsible for the power a grphxcrd can give.
>
> 3. Can i expect this to be fixed within the time to buy new hardware anyways.
> Theory meaning: after 2 years everybody is bound to buy new hardware anyways
> so why bother fixing it.

> The answers to these questions do mean alot to me, and im sure to many other
> people aswell as this will affect all financial and IQ-rated thinking of
