Core i7 Affinity

[Sydwayz]

Thank you all for your help.
I am also getting the best results from setting affinty for all accounts to all 8 cores.

Is there a way to set that in the config.wtf file like we used to?

What would be the processaffinity number for all 8 cores?

Thanks again

If the setting works as described in the link at the top of this thread, the number would be 255. You can test to see if it works by putting that number in the config file, starting WoW, opening Task Manager, selecting Processes, right-clicking WoW, selecting Set Affinity, and looking at the Processor Affinity window to see whether WoW has set itself to run on all CPUs.

(Those are instructions for Vista; XP might be a little different.)

255 worked for me, on a vista system :-)

I bought me a new q6600 and i set the config on "15", but now i get in Alterac over 85% CPU usage on all 4 cores - nearly all the time, can someone tell me if this is normal ??

This is normal

I just want to make sure I understand your other numbers. When you say 01234567, do you mean WoW1 is on 0 and 1, WoW2 is on 2 and 3, etc.?

Yes.

Yes, all instances are set to 0 and 1 if you just launch the clients in a normal fashion.

That's the same for me :-)

Could one of you check something? Launch four WoWs from scratch without setting the affinity manually in any way (including not in WoW's config file).

How do you do that? - the thing in bold! :-)

As for my performance in general. I am running around with 40 fps in Dalaran on the main (15 fps on slaves), full view distance, full spell details, and full environmental details!

System specs please!


So your getting 40+ on main and 15+ on each slave(4)? and in dalaran!????

I am now looking at setting affinity, I did search and found this thread.

Brilliant thread....great example of how good this community can be...I cannot imagine anywhere else that the combination of knowledge, experience and real-life testing would come together

Would be good to include some/all of this in the wiki

Thanks to all the contributors in this thread

So far as I know, Microsoft has never documented the thread scheduler's algorithm.

I don't remember what I was thinking when I wrote that but there is actually quite a bit of info about this in "Windows Internals," a standard reference book published by Microsoft Press. (Pages 391-450 of the fifth edition.)
