World Of Warcraft: Cataclysm--Tom's Performance Guide

By Chris Angelini
published

Ready for the launch of Blizzard's World of Warcraft: Cataclysm expansion tomorrow? Is your PC? We test 24 different graphics cards from AMD and Nvidia, CPUs from AMD and Intel, and compare DirectX 9 to DirectX 11, showing you which settings to use.

Effects: Shadow Quality

There are five options for the Shadow Quality setting.

  1. Low: Low-resolution terrain shadows, blob shadows for units
  2. Fair: Low-resolution terrain shadows, low-resolution dynamic shadows near player
  3. Good: Low-resolution terrain shadows, high-resolution dynamic shadows near player
  4. High: High-resolution environment shadows, high-resolution dynamic shadows near player
  5. Ultra: High-resolution dynamic shadows for the entire scene

Shadow Quality: Low

The blurry shadow of the tower to my left is a good example of low-res terrain shadows. And the fact that you don't even see the shadow of my mount is a good indication that we're using the Low setting here.

Shadow Quality: Fair

The tower still creates that blurry shadow, but now there's at least a low-res dynamic shadow under the drake.

Shadow Quality: Good

It's difficult to see the difference between low-res and high-res dynamic shadows cast by my mount when I'm up in the air, but if you compare the blown-up versions of this shot to the previous one, you do see the shadow becoming crisper.

Shadow Quality: High

Of course, the difference between High quality and Good is most apparent from the tower's low-res (blurry) shadow giving way to a much sharper high-res version. We've certainly seen more realistic shadow implementations (at such a distance, shadows aren't usually so sharp). But this is an MMORPG, after all, and it's hard to knock the realism of a fantasy world.

Shadow Quality: Ultra

    Kind of unfortunate to see if I had gone with an i5 750 instead of a 955 I'd be seeing more fps. Although the money I saved for the same frames in most other games leaves me happy.

  • WOW only uses 2 cores by default. However youc an configure it to "quasi" use more cores. you have to manually edit your config.wtf and change the variable: SET processAffinityMask "3" (3 is the default meaning 2 cores) to the following values for respective processors:

    i7 Qudcore with Ht- 85
    Any Quadcore chips with no HT - 15
    i5 Quadcore which does not have HT as far as I know - 15
    i5 Dualcore with HT- 5
    Dualcore with HT- 5
    Dualcore without HT - 5
    AMD tricore - 7

    There used to be a blue post explaining the settings and how to calculate it for different cores. But the old forums got wiped.

    not a that big fan of wow, but still happy to see that they do keep in mind that people also have low end hardware too.

    I'm impressed, if Chris went to all that trouble to benchmark the new expansion for a mmorpg in such great detail it can me only 2 things:
    1. Chris is a closet WoW-player
    2. Really bored
    With that said, i really do hope to see more of these articles, albeit with a more demanding title on the bench, even if it's from a "lesser" developer/publisher combo.

    PS: I do hope ppl appreciate my sense of humor :P

    Damn fine job Mr. Angelini, the most comprehensive hardware guide i've ever seen for WoW. This will save me hours, if not days of time when talking to players about their systems. Much appreciated.

    The Intel CPU scaling part was lacking...i7 980X at 3.7GHz? For WoW? Really?

    And why only Corei CPUs? Where are all the Core2s? 75% of Intel users still use Core2s and 775s!

    Simply astounded by the time and effort that must have went into this piece. It also makes me greatly look forward to my new Maingear desktop arriving on the 23rd just in time for Christmas. Dual OC gtx580s in sli with a corei7 FTW. Ultra everything here I come!

    It's a little easier to talk about WoW since I've been playing it for way too long, but I definitely want to see us doing more comprehensive coverage of demanding titles on launch day. It's all a matter of trying to convince the software guys to give a hardware site early access to the game. That's the hard part :)

    With hardware-accelerated cursor now enabled, OpenGL has finally become usable in WoW; was there any testing done on that? Not only does it sometimes give a boost to Nvidia cards, it's also the 'default' setting for Linux players - incidentally, the ones who were asking for the feature for a while.
