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: Liquid Detail

There are four options for the Liquid Detail setting.

  1. Low: Animated liquid textures, texture-based ripples, and no reflection
  2. Fair: Normal map liquid textures, texture-based ripples, and no reflection
  3. Good: Normal map liquid textures, procedural ripples, and screen-based reflection
  4. Ultra: Normal map liquid textures, procedural ripples, and full reflection.

The new liquid rendering system was added in patch 4.0.1, and it reflects (oof, terrible pun) a significant improvement to the way water looks in this game.

Liquid Detail: Low

The animated liquid textures and texture-based ripples are, despite Blizzard's efforts to make them look good, very non-interactive. Once you've seen the higher settings, you won't want to go back to Low detail here.

Liquid Detail: Fair

Adding the normal mapped liquid textures has a profound impact on the water's realism from a distance, even if the ripples are still very generic compared to the next step up in fidelity.

Liquid Detail: Good

The screen-based reflection added with Good quality liquid detail helps with realism close-up, as you no longer have what appears to be transparent water. The procedural ripples are pretty cool; when you run through a river or "buzz the surface" of a lake on your flying mount, you get ripples that trail you and dissipate outwards.

Liquid Detail: Ultra

Jumping up to Ultra quality liquid detail incorporates a full reflection. As you can see in the screen shot, the rocks and trees get reflected into the background lake. This is especially noticeable when you're flying and all of the environmental details are reflected back as you'd expect.

    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!

    i hate you so much tom's hardware ... now i have to go buy an intel proc instead of my phenom ii x4 :D ... and add a dx11 board on top of it ... oh well, there goes my santa's gift :P

    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.
