    I'm a bit confused... Here you said to set for an I5 w/o HT to 15, but on wowwiki says 15 to use all the cores and 7 to optimal?
    Which one should i use?

    The idea of high FPS is not to simply get the max, going from 80 to 100 for example. You want to increase the low end of your FPS (think raid/battleground with tons of spells characters) that is where you will notice the FPS increases.

    Pretty amazing how you can provide us first with useful info, and then put this nonsense up

    Great guide, but I have to nitpick here, since it's a pet peeve whenever someone starts talking about how many "FPS" the human eye can see. Our eyes, in fact, do not see in "frames," but in continuous light. From a biological perspective, there's no known limit to how many FPS we can therefore detect. Personally, I can notice the difference between 60 and 100 FPS (on a 120hz screen, of course.) But my best friend says he can't really tell a difference between 30 and 60. It's all subjective.

    As for Xeons... they're a really weird chip, and I found out quickly that I don't know enough about them to give proper advice, other than telling you to seek details here:
    http://en.wikipedia.org/wiki/Xeon

    I saw something in there about quad Xeon still only accepting single CPU operations or something like that, so I don't know if it actually behaves the same as today's quad cores, and same goes for their HT. You'll probably have to do more reading about it yourself...
    If it's actually like having two quad core HT processors then that would make make 16 threads... There's probably no need to allocate WoW to the last few threads because the whole point of this stuff is to just get the game off the threads that the OS would be using, not to stick wow at the highest number threads. You could probably just pick a number that works for single quad cores with (84 or 252) or without HT (14) and it might still effectively mask the first core so that game avoids it.
    I'm sorry, but I actually went and read AMD specs for my processor and did not find any info on HT.
    Which i should have known means they have no such thing, that was the only thing I was missing.
    15 it is.

    BTW great thread! I will go and check my TCP settings also, I play a lot of PvP and I was disappointed at how low FPS I have even though my PC is so strong.

    Quick thing. I have W7 and DX 11. I tried adding that line you posted and sure enough my fps went up a few notches but now I cant see any water unless it's on low. I used to have it on ultra. Any idea what's going on? Yes, I had the water working right before I added the line.

    Thank you

    You have your binary / cores backwards.
    Binary is read right to left generally (easier to start big and work down), but that doesn't mean the numbers are written backwards;
    Base2
    2^0 2^1 2^2 2^3 .. 2^7
    1 2 4 8 16 32 64 128
    (1 byte)

    for cores 3/4 - CVAR value 80

    |C(v)4|C4| |C(v)3|C3| |C(v)2|C2| |C(v)1|C1|
    0 1 0 1 0 0 0 0
    So 0101 is actually 2 + 16 which would be 18.
    To get 80 its the inverse;
    00001010

    So really your cores pan out;
    C1|C1v|...|C4|C4v
    As originally stated

    This bugged me too, only because there have been practical studies which put the minimum refresh rate of a display necessary for the human eye to accept what they see as "real" much higher than this number the guy pulled out of thin air with no basis.

    It's true that we see basically a continuous exposure but Showscan was developed by Doug Trumbull in the late 70s based on biometrically measuring a viewer's response to changes in frame rate. Refresh rates higher than 72fps are where no change in response was measurable in the viewer. And that's objective data.

    Of course not responding in a measurable way does not equal an inability to perceive (though it is an odd concept). It's pretty easy to conclude, however, that refresh rates above those we actually respond to are practically irrelevant while refresh rates below those we actually respond to aren't insignificant, like the author seems to think.

    I have a question about the SET processAffinityMask "84"

    After everytime I open warcraft I look back into the config folder and my value has been reset to 0, so I can change it back to 84, open and close wow and it is already back to 0. Any ideas?

    Do I just type in a new CVAR of "SET processAffinityMask "5" " myself?
    Yes you can do that.

    However, if you dont have a dual core with HT / quad / hex core this will not help you much as WoW will already be running over both of your available cores by default.

(See post #19)

    If you upgrade to more cores someday the line to add to the bottom of your config.wtf file is:
    SET processAffinityMask "84"

    I would appreciate it greatly!

    As far as I can tell none of these AMD processors have any type of hyperthreading technology. Which means they just have the four (quad)/ six (hex) logical cores.

    So, for the phenom x4, you would use 15.

    Same as the "i5 Quadcore which does not have HT " in the OP.

    For the record, WoWWiki suggests setting 85 for Core i7 w/ HT.
    In short, it is not recommended to run anything specifically over the "virtual" cores. Virtual being the hyperthread cores.

    You will see no significant gains by running anything over the HT cores, and if anything can actually cause the CPU to bottleneck, which will actually hinder performance.

    I did FPS tests with a setting of 255 and actually saw a drop in fps.

    That is a really really good question.

    I do not believe this will apply in Mac. As you said, since Leopard GCD handles the majority of application threading, not sure if you can over ride that at all.

    I am also not sure if WoW is written to take advantage of GCD. You have to block the code of an application for GCD.

    That part would be a really good question to ask perhaps on the Blizz technical forums. Kind of curious what the answer would be.

    What OS are you using for your dual quad set up?

    I am not sure where they are getting 7 from. But that doesn't appear logical.

    The values for the i5s have been tested, and proven to function as expected.

    Perhaps that page should be edited, proven out.

    Very true. Except in my specific case my system does not dip below 75fps, and that is only because I have vertical sync enabled which limits your fps to the refresh rate of your monitor which in my case is 75hz.

    That was how I had originally placed the cores, and that seemed logical and correct to me.

    When this guide was originally posted on guild forums before bringing it here, someone suggested that was incorrect and to reverse it.

    Interesting.

    I wish it were possible to edit the OP. Lots of corrections / additions I would like to make to it.

    I don't think they are insignificant.

    I was mostly speaking from personal experience, and I do not have super eyes.

    The human eye is actually, and obviously, not perfect. Even for those of us who have 20/20 vision.

    In any event. I would remove that line if possible since it seems to be aggravating some people.

    start / run / regedit

    Once inside registry editor hold down cntrl + f (control key and f key at the same time). Alternatively you can click the edit button at the top left of the window and click on find.

    This will open a small dialogue box copy and paste that string value 0cc5b647-c1df-4637-891a-dec35c318583 into the find box.

    The rest should be simple.

    Nope.

    The dx11 mode is only experimental anyway, and with dx10 you will see no benefit.

    You need dx11 installed on your os, which you should have with windows 7, but you also need a dx11 capable gcard to take advantage of it.

    Strunker,

    Could you please clarify this for me - you recommend leaving the primary core unused and at the same time in the post above you said "So, for the phenom x4, you would use 15."
    Looking at the graph posted on page #1 the number for "Quad-core, non-primary core" is in fact 14. Which number would be optimal then.

    Cheers,
    Krs

    I noticed some asking right value for processAffinitymask with phenom 2 x4 965 BE, and i saw it says that use "15" but im kinda supprised since fps on Stormwind mass is 45 with "15" and of course I read first post and it says that "15" or "84", I tried to put "84" but it keep changing it to "0" when I launch wow.

    The point of setting the affinity mask is to have wow run on whatever cores you specify. In my specific case, I have wow running over physical cores 2,3,4. So that if I am multitasking while playing, and running other things I dont have to worry about any cpu bottle necking.

    For most people, none of these tweaks are "necessary". It is mostly just for those who like to run as optimally as they can. Efficiency is a quality we breed in people here, and I carry it over to every aspect of life.

    ---------- Post added 2011-01-10 at 03:40 PM ----------

    Yes. Wow does have three main cores now as of 3.0 I believe, or 3.3. One of those patches split the game into 3 main threads, with a bunch of other filler threads.

    I did a bunch of tests when I first wrote this article last year on my guild's website.. Below is a quote from the thread...

    I dont see any reason to run wow over the virtual cores. In fact, in most cases, it is recommended to not run anything over the virtual cores and let the software (OS) dictate what processes are scheduled for them. In the below test I actually had lower overall fps with 255 than when I forced it over the last 3 physical cores.

    Test | Mask Value | Avg FPS in Dal
    _________________________________
    1) 80 19

    2) 85 23

    3) 84 24

    4) 255 21 ( not recommended)

    ________________________________

    80= Forces wow to run on physical cores 3/4, cores 1/2 are not used by wow. Total cores used 2.

    85= Forces wow to run on all physical cores 1/2/3/4. Total cores used 4

    84= Forces wow to run over physical cores 2/3/4. Total cores used 3. This is what I am predicting to be the best option. As it will leave core 1 open(which is the default core most windows application run over) for other windows functions meaning the system will remain stable while the other 3 cores handle all the wow processes. Since wow has tri-core support and a main thread isnt going to be going over the 4th core it seems almost wasteful to give the game access to anymore than 3 cores.

    255= Forces wow to run on all physical cores plus all of the HT cores 1/1a/2/2a/3/3a/4/4a. Total cores used 8.

    _____________

    I would go with either 84 or 85. Both seemed pretty solid and I noticed a substantial increase in load time with 84 so that is what I am sticking with.

    ---------- Post added 2011-01-10 at 03:44 PM ----------

    And yes there is no tcpack in vista/7, perhaps I should have specified that in the post.

    However, there is TCPnodelay.

    Tcpnodelay is directly related to the Nagle algorithm, and disabling Nagle is still a huge huge decrease in MS latency. I highly recommend everyone does it manually, or use the Leatrix tool from wowinterface.com
    Just what I needed to know, I will be using 84. I'm at work, so you are saying the config file all we have to change is the CVAR to 84 or do we have to include the binary stuff?
