Quad core in xp

[FilluX]

Hello! i dont remember from where i heard this, but someone wrote/said that xp does not support quad core processors, that it can only use 1 core?

Is this only bull**** or is it true?

I'm pretty sure that mine recognices all four, because when i run some cpu stress tests and open everest it says that all four cores are running at 100%, i just want to be sure.

Thanx

XP SP2 (doesn't matter if it's Home or Pro) supports both dual and quad core.
I have heard though that Vista handles multi core processors better since it was written with multi core processors in mind.

Ok thanx for the info!

XP SP2 ...

Just curious -   what about pre-SP2 ?

Good question Willy...
There were performance issues with dual cores that was corrected with SP2.

That's interesting.

I see it also says:

... Additional updates are available to optimize performance and behavior on computers that are running Windows XP SP2. Without these updates, computers that are equipped with these power management-capable, mobile, dual-core processors may experience decreased performance or unexpected behavior.

and it looks like  "Download the WindowsXP-KB896256-v4-x86-ENU.exe package now."  is what that refers to.


OT side note:
I see another link there:
http://support.microsoft.com/kb/909944/
"Game performance may be poor on a Windows XP-based computer that is using a dual-core processor"
that looks like info that would often be useful to the gamer folks that frequent CH.



Thank you.

Just to clarify http://support.microsoft.com/kb/909944/ refers to a problem with 64 bit XP. 64 bit is actually a completely different codebase than 32bit so this problem is likely not to be applicable for 32 bit.

Nothing to see here, move along.

Only 64 bit?

Sorry, my brain seemed to have had a neuron misfire.

APPLIES TO
•   Microsoft Windows XP Home Edition
•   Microsoft Windows XP Professional
•   Microsoft Windows XP Professional x64 Edition

I have no idea how I came to the conclusion it was only for 64 bit...
I think I better log-off for today.

But the article is pretty old and the performance issue only occurs if the game programmers use a special function to calculate timing.
So I think it's pretty safe to assume most games released after 2005 aren't affected by this issue.

hahahaha
You see -  I saw that too,  along with the part above it that was about 64 bit.
I read.
I re-read.
I thought I was overlooking something somewhere.

Welcome to the human race.

Nah.   We're having too much fun.

Ah.
Ok.
Makes sense.
Thanks for that insight.
